▼ Carbazole-bis(oxazoline) (Czx) lanthanide dialkyl, CzxLn(CH2SiMe3)2, and dichloride CzxLnCl2(THF)n, complexes were synthesized by protonolysis and salt metathesis protocols. The X-ray crystal structures of CzxLn(CH2SiMe3)2 (Ln = Er and Yb) and CzxLnCl2(THF) (Ln = Y, Er and Yb) were determined. The carbazole-bis(oxazoline) ancillary ligand provides high stability but relatively low activity in some reactions for the corresponding lanthanide complexes, possibly due to steric crowding caused by the dimethyl groups on the oxazoline ring. The synthesis of a series of divalent ytterbium monohalide complexes, CzxYbX(THF)2 (X = I, Cl) or CzxYbI(DME) was achieved by salt metathesis or sodium amalgam reduction methods. The salt metathesis reaction of CzxYbI(THF)2 with Li(CHSiMe3)2 or NaN(SiMe3)2 gave the corresponding divalent ytterbium alkyl and amide complexes, CzxYb[CH(SiMe3)2](THF) or CzxYb[N(SiMe3)2](THF), respectively. The solution behaviour of CzxYbI(THF)2 was investigated via variable temperature NMR spectroscopy and supported a dynamic process involving dissociation of THF at, or above, 280K. Similar dynamic solution behaviour was found in other divalent ytterbium complexes as well. Reaction of 2,2’-bipyridine with CzxYbI(THF)2, afforded a trivalent ytterbium complex with a coordinated bipyridyl radical anion illustrating that the divalent complex is a strong, one electron reducing agent. Despite this, treatment of CzxYbI(THF)2 with LiCH2SiMe3 gave a trivalent ytterbium dialkyl complex, CzxYb(CH2SiMe3)2, also prepared by salt metathesis starting from CzxYbCl2(THF) and LiCH2SiMe3. Reaction of the trivalent ytterbium dialkyl complex, CzxYb(CH2SiMe3)2, with a primary aryl phosphine, ArPH2, (Ar = Mes, Is), unexpectedly formed the divalent ytterbium secondary phosphides, CzxYb(PHAr)(THF)2. The same ytterbium phosphide complexes were also prepared by salt metathesis starting from either the divalent CzxYbI(THF)2 or the trivalent CzxYbCl2(THF) complexes. Non-reducible lanthanide dichloride complexes, CzxLnCl2(THF) (Ln = Sc, Y, Er) reacted with sodium aryl phosphides (NaPHAr) to generate the lanthanide mono(secondary phosphide) complexes, CzxLnCl(PHAr)(THF).

▼ The purpose of this research is to synthesize new compounds containing lanthanides. Using slow diffusion crystallization methods and solid-state synthetic techniques, different families of compounds comprising lanthanides were synthesized and characterized by X-ray diffraction methods. Magnetic susceptibility measurements were also employed to characterize a new zirconium compound and to study the magnetic behavior of a family of isostructural reduced lanthanide-bromide clusters. Four different families of compounds were synthesized by slow diffusion using trinuclear lanthanide complexes supported by TDCI (1,3,5-tris(dimethylamino)-1,3,5- trideoxy-cis-inositol), [Ln3 (TDCI)2 (H2O)]6]³⁺, and metallocyanates as linkers. The combination of [Cr(CN)6]³– and trinuclear complexes having the lanthanide ions Gd³⁺, Tb³⁺ and Dy³⁺ results in a family of compounds that features 1D-chains. [Fe (CN)6]³– couple with trinuclear complexes containing Gd³⁺ - Er³⁺ yields a family of compounds featuring 2D-networks. Using [Co(CN)6 ]³–, a new family of compounds characterized by 1D-chains is obtained when the trinuclear cluster has the lanthanide ions Ho³⁺, Er³⁺ and Y³⁺. The last family of compounds was discovered when utilizing tetracyanometallates, [M(CN)4]²– (M = Ni, Pd and Pt); this new family of compounds is composed of two trinuclear complexes and three linker units. The solid-state synthesis using lanthanide bromides resulted in clusters with the Y6 I10Ru-type structure, Ln6Br10Co (Ln = Gd, Tb and Er) and Tb6Br10Ni. Magnetic susceptibility of the Ln6Br10Co compounds, with 17e^– per cluster, revealed that these compounds exhibit intracluster ferromagnetic coupling while the compound Tb6Br10Ni, with 18e^– closed-shell configuration, does not. The encapsulation of C resulted in three new isostructural compounds adopting the form of Gd10C4Cl18, Ln10Br18 (C2)2 (Ln = Gd, Ho and Y). A new reduced zirconium compound, [Zr6MnI12]4[MnI4]3, was obtained by solid state synthesis. This new compound has Mn atoms in two different environments, as interstitial and in tetrahedral cavities, and has three axial iodides. These features are not known for other zirconium-cluster compounds or the lanthanides. Computational methods were employed to obtain the energies and the frontier molecular orbitals of three different spin patterns of a dinuclear gadolinium complex. The involvement of the f-orbitals of the gadolinium ions help to understand the observed magnetic behavior. A structural optimization of Zr6MnI12 was also performed using DFT methods, and a reasonable structure and its frontier orbitals were obtained. In conclusion, the lanthanides have shown to be very versatile in the synthesis of new compounds. Using slow diffusion crystallization, we synthesized four different families of compounds having trinuclear lanthanide complexes and metallocyanates; by solid-state synthetic methods, we obtained reduced lanthanide clusters and a new reduced zirconium iodide compound, which were characterized by X-ray diffraction methods and… Advisors/Committee Members: Hughbanks, Timothy R (advisor), Dunbar, Kim R (committee member), Son, Dong Hee (committee member), Naugle, Donald G (committee member).

▼ Time-resolved, Luminescence Resonance Energy Transfer (LRET) imaging using lanthanide probes was shown to be a faster and more sensitive means to visualize dynamic interactions of proteins in living cells when compared to conventional steady state imaging of Förster Resonance Energy Transfer (FRET). This dissertation provides a theoretical description of LRET imaging with lanthanide probes as well as experimental results showing: i) syntheses of luminescent terbium complexes that bind specifically and stably to Escherichia coli dihydrofolate reductase (eDHFR) fusion proteins; ii) that terbium complexes can be delivered into the cytoplasm of living cells; and iii) that intracellular interactions between transgenically expressed eDHFR fusion proteins (labeled with terbium complexes) and transgenically expressed GFP fusion proteins can be imaged by detecting terbium-to-GFP LRET with a time-resolved fluorescence microscope. This dissertation also describes detailed protocols for practical implementation of the experimental methods. Time-resolved LRET microscopy was used to detect interactions between two epithelial tight junction protein domains: the first PDZ domain of ZO-1, fused to eDHFR and the cytoplasmic, C-terminal YV domain of claudin-1, fused to GFP. Interactions were detected in single microscope images at sub-second time scales, and a highly significant (P < 10-6), six-fold difference between the mean, donor-normalized LRET signal from cells expressing interacting fusion proteins and from control cells expressing non-interacting mutants was observed. The results show that time-resolved, LRET microscopy with a selectively targeted, luminescent terbium protein label affords improved speed and sensitivity over conventional FRET methods for a variety of live-cell imaging and screening applications.

▼ This project involved utilising the Brønsted basic nature of polar organometallic compounds DyCp3 and [Fe{N(SiMe3)2}2], to deprotonate organic compounds that contain an acidic H-N bond to form low co-ordinate compounds that can then aggregate together to form polynuclear cage compounds. Using DyCp3 in a reaction with BtaH, a dimer formed, [(η5-Cp)2Dy(µ-Bta)]2. This dimer is a single-molecule magnet. [(η5-Cp)2Dy(µ-Bta)]2 was compared to a previously reported compound [(η5-Cp)2Dy{µ-N(H)pmMe2}]2 which, despite having a similar structure to [(η5-Cp)2Dy(µ-Bta)]2, is not a SMM. Synthesis of a chlorine- bridged dimer [(η5-Cp)2DyCl(THF)]2 and subsequent magnetic measurements confirmed that [(η5-Cp)2DyCl(THF)]2 is a SMM. Removal of the THF ligand from [(η5-Cp)2DyCl(THF)]2 was achieved via sublimation. The product of this sublimation was a mixture of two different polymorphs of the same compound, [(η5-Cp)2DyCl]2 and [(η5-Cp)2DyCl]∞. [(η5-Cp)2DyCl]2 was shown to be a SMM, and [(η5-Cp)2DyCl]∞ was shown to display SMM behaviour. [(η5-Cp)2DyCl]∞ had the largest energy barrier to relaxation of magnetisation for any known homospin dysprosium(III) compound. Using [Fe{N(SiMe3)2}2] in a reaction with HppH resulted in the formation of [{Fe{N(SiMe3)2}(hpp)2}2Fe]. [{Fe{N(SiMe3)2}(hpp)2}2Fe] displayed anti-ferromagnetic exchange between the iron(II) centres which resulted in a ground spin state of S = 2. Reacting [Fe{N(SiMe3)2}2] with BtaH resulted in the formation of [{(Me3Si)2NFe}4Fe(Bta)6]. Despite repeated attempts [{(Me3Si)2NFe}4Fe(Bta)6] could not be re-synthesised. An alternative “one pot” synthetic method was attempted, this resulted in the formation of [Fe{N(SiMe3)2}2(LiBta)]2. The structure of [Fe{N(SiMe3)2}2(LiBta)]2 was described using ring-ladder principles and magnetic studies revealed weakly anti-ferromagnetically coupled iron(II) centres which displayed a large zero-field splitting. Extension of the one-pot synthetic route to the use of tin halides was conducted. Using SnCl2 in the one-pot synthetic route resulted in the formation of [{(Me3Si)2N}8Sn8Li8Cl4(Bta)12]. Whilst using SnBr2 resulted in the formation of the compound [{(Me3Si)2N}8Sn8Li8Br4(Bta)12]. The charge separated compound [{(THF)2Li(Bta)}3{Li(THF)}]2[SnI4] was the result of using SnI2 in the one-pot method.

▼ The structural chemistry and the resultant properties can be exquisitely controlled in the f-block elements because in both the 4f and 5f series the decrease in ionic radii is extraordinarily systematic. The 4f and 5f ions can be coordinated with six to twelve oxygen atoms yielding a vast range of coordination geometries. Structure-property correlations of lanthanide-containing materials are being heavily investigated owing in part to their potentially useful applications in magnetism, ion exchange, fluorescence, and optical properties. For actinides, the electronic configurations and magnetic properties are difficult to ascertain particularly because of orbital hybridization, relativistic effects, and narrow bandwidths. Exploration of this field is filled with multiple opportunities but also challenges. Furthermore, owing to the similarities in ionic radii and coordination environments between lanthanides and actinides, it is interesting to compare the chemistry of the f-block elements using solid-state chemistry techniques. In this present work, we probe the structural chemistry of f-block elements using tellurite as the ligand to address the aforementioned questions. The reason tellurite was chosen as the ligand in this study is due to the presence of stereochemically active lone-pair electrons on the TeIV centers and the large variability in the coordination environments that the tellurite anions play in the crystalline architecture of this family of compounds. Tellurite anions can be further interconnected to form dimers, trimers, and polymeric structures, which enable a variety of unusual structures to form. Hydrothermal reactions were conducted in the synthesis of f element-containing tellurite compounds. Single crystal X-ray diffraction and powder X-ray diffraction studies were performed to elucidate the structure of the novel products. A superconducting quantum interference device (SQUID) magnetometer was used for the magnetic behaviour studies. Energy-dispersive X-ray spectroscopy (EDS) techniques were utilized for the elemental analysis. Spectroscopic techniques like UV-vis-NIR were also applied to identify the oxidation states and electronic transitions for f elements. This dissertation is focused on crystal chemistry, structure-property relationships, and possible applications of the f-block element containing materials. More than 120 new lanthanide or actinide containing compounds were synthesized in this study. Lanthanide and actinide tellurites show remarkable structural diversity from a crystallographic point of view and atypical physical properties of these compounds were discovered. Materials with special physical properties, for example magnetic behavior (Chapter 2, 4) and electronic properties (Chapter 3, 5), are discussed. Cationic frameworks materials (Chapter 6, 7) with potential anion exchange abilities are also presented. Besides the physicochemical property studies, structural comparison between 4f-block compounds (Chapter 8), as well as between 4f and 5f compounds… Advisors/Committee Members: Edward J.

▼ Metallacrowns (MCs) are highly tunable complexes which have seen a wide range of research application including single-molecule magnets, host-guest studies and Ln-luminescence. The first near-infrared (NIR) emitting MC was a lanthanide-zinc metallacrown (LnZn16) which can image human HeLa cells. Recently these MCs have expanded to include systems with gallium. This thesis focuses on the development of new structure types for GaMCs and the systematic modification of existing gallium based metallacrowns via alterations to the hydroximate ligands which act as antenna for lanthanide sensitization. A new LnGa6L9 complex is described that has a higher antenna to Ln ratio compared to previously reported GaMCs to explore the relationship between the number of hydroximate ligands and Ln sensitization. This is important since the luminescence intensity (brightness) of the Ln emission is the product of the molar absorption and the quantum yield (QY). The structure contains six Ga(III) with a single Ln(III) encapsulated within a framework that matches a [3.3.1] organic cryptate. This metallacryptate sensitized Pr3+, Nd3+, Sm3+, Tb3+, Ho3+, Er3+, and Yb3+ emission, and increased the molar absorbance to 4.5.104 M-1.cm-1. However, the QYs tended to be lower than previous GaMCs due to the proximity of high energy N-H oscillators, so the brightness of each series was similar. Slow magnetic relaxation was also studied and observed for Nd3+, Dy3+ and Yb3+; however, only Dy3+ exhibited a real relaxation barrier (Ueff = 12.7 K). These complexes could allow preparation of dual addressable “smart materials” which take advantage of both the luminescent and magnetic properties of Ln ions. New GaMCs prepared with 5-iodosalicylhydroximate and/or 5-iodoisophtalate ligands were investigated for three objectives. First, ring substitution on the hydroximate led to red shifted maximum absorbance from 310 nm to 325 nm π-π* bands. Second, iodide could enhance intersystem crossing (ISC) which might aid lanthanide sensitization. Enhanced sensitization efficiency is observed when iodide is on carboxylate ligands in the case of Er3+, but the cause is not yet known. Third, X-ray attenuation by these heavy atoms could yield bimodal MC based luminescent/computed tomography (CT) contrast agents. Both monomeric and dimeric gallium 12-MC-4 complexes were made, and diffusion ordered spectroscopy (PGSE-DOSY) showed that only the dimeric complexes were solution stable. So, three combinations were made which had 4, 8, or 12 iodides on the MC. A positive correlation between quantum yield of Ln emission and iodide content was observed in the case of Sm3+ and Er3+ (up to 3.35% and 1.82.10-2% respectively), suggesting a relationship between enhanced ISC and Ln emission. The brightness of these complexes were similar to a reported analog with no iodides. The ability to attenuate X-rays in DMF solutions was demonstrated, showing that these metallacrowns could be used as bimodal agents.

▼ Understanding the behaviour of actinide species is of importance when removing and processing all nuclear waste. Examples include the safe clean-up of contaminated waste ponds and aspects of the TALSPEAK (Trivalent Actinide-Lanthanide Separation by Phosphorus Reagent Extraction from Aqueous Komplexes) process.The chemistry of the ponds and the TALSPEAK process has been studied by probing the aqueous solution behaviour of Ln(III), Am(III), Cm(III) and Th(IV) ions in the presence of organic (EDTA4- (ethylenediamine tetraacetate), DTPA5- (diethylenetriamine pentaacetate) and lactate) and inorganic (CO32- (carbonate) and OH- (hydroxide)) ligands by a variety of techniques including Nuclear Magnetic Resonance (NMR), Ultra Violet-Visible (UV-Vis) and luminescence spectroscopies, as well as potentiometry.Various ternary complexes have been shown to exist, including [M(EDTA)(CO3)]3-(aq), (where M = LnIII, AmIII or CmIII) and [Th(EDTA)(CO3)2]4-(aq), which form approximately over the pH range 8 to 11, and also [M(EDTA)(lactate)]2-(aq) (where M = Ln(III) or Am(III)) and [Th(EDTA)(lactate)]-(aq), which predominantly occur over the pH range 4 to 6. The nature of lactate interaction with [M(DTPA)]2-(aq) complexes (where M = Ln(III) or Am(III)) is unclear, as it may be possible that lactate can coordinate directly to the metal ion or to the acetate groups of DTPA5- (via a H-bonding interaction). The knowledge gained in this research has given a deeper insight into the nature of lanthanide and actinide coordination chemistry in mixed-ligand environments. For example, the increasing solubility of actinide metal ions in the contaminated waste ponds is probably due to the ability of organic ligands present in the ponds to solubilise metal ions at high pH, and also under TALSPEAK conditions of pH 3.5, there is likely to be minimal interaction of lactate with the [Ln(DTPA)]2-(aq) complexes.The determination of metal ion speciation using a combination of NMR, UV-Vis and luminescence spectroscopies, coupled with potentiometry, could be applied to new characterisation challenges faced in the future of the nuclear industry.

▼ The current “gold standard method” of detecting cancer relies on microscopic examination by specialised pathologists.33 However, there are risks associated with surgery and biopsies and so the ability to diagnose cancer and other diseases in a non-invasive manner is highly attractive. There are many imaging techniques suitable for this, each with their own advantages and disadvantages, which can be improved by the use of contrast agents.12, 34-37 The incorporation of targeting vectors allows for the specific imaging of desired tissues.12, 38-41 Further to this, the incorporation of more than one contrast agent into one imaging agent allows for multi-modal imaging of cancerous tissue and other diseases. This allows for the advantages of different techniques to be used simultaneously and is an emerging field.37 The methods for the synthesis of these drugs can be synthetically demanding and low yielding due to linear synthetic strategies. The use of multi-component reactions would be a major benefit and the Ugi reaction is particularly attractive due to the incorporation of four components and the biocompatible bis-amide motif of Ugi products.42, 43This work serves as an extension to previous work based on Ugi reactions of metal complexes, which showed that amine and carboxylic acid appended lanthanide and carboxylic acid appended d-metal complexes can be used as stable building blocks in the formation of mono-metallic complexes.1, 2 This work presents the synthesis of aldehyde appended lanthanide complexes and their use in Wittig and Ugi chemistry in the synthesis of mono-metallic complexes. The previously synthesised amine appended lanthanide complexes1, 3, 4 were also synthesised to be used as a feedstock in subsequent Ugi reactions. A number of carboxylic acid appended d-metal complexes and cyanine dyes were synthesised according literature procedures.1, 13, 14, 44-49 Both the bis-acid appended d-metal complexes and cyanine dyes were used unsuccessfully in the Ugi reaction. However, the mono-acid d-metal complexes were used successfully in the Ugi reaction in keeping with previous reports.1 These were used as the third feedstock for the synthesis of trimetallic complexes along with the aldehyde and amine appended lanthanide complexes via the Ugi reaction.In addition, a number of Ugi reactions were performed on organic compounds. The use of p-toluic acid gave five Ugi compounds, which were characterised and gave the expected results. However, the use of biotin as the carboxylic acid component gave four compounds that were complex to characterise and suggested that the incorporated biotin may not serve as a viable targeting vector. One of the p-toluic acid Ugi products was reacted further and a biotin moiety was incorporated with a (CH2)6 spacer. Spectroscopic evidence suggested that the biotin would still act as a viable targeting vector.Overall, this work serves to set the scene for the synthesis of targeted tri-metallic multi-modal imaging agents using stable metal complexes as building blocks in the Ugi reaction.

Les complexes luminescents d'ions lanthanides(III), de par leurs caractéristiques spectroscopiques, sont des alternatives intéressantes aux fluorophores organiques usuels pour des applications dans le domaine de la bioanalyse et de l'imagerie cellulaire. Les propriétés photophysiques de ces types de complexes sont notamment exploitées en tant que donneur de FRET en temps résolu permettant d'améliorer la sensibilité et la spécificité de la détection. Des développements récents ont aussi permis d'obtenir des sondes luminescentes pour le pH physiologique, pour divers analytes endogènes ou pour des compartiments cellulaires. Dans ce cadre, l'enjeu est d'obtenir des luminophores plus brillants pour une détection plus performante. Pour ceci, nous avons souhaité, par deux approches, apporter des modifications à une plateforme nonacoordinante pyridinophane présentant trois antennes pyridine et possédant trois bras acétate. D'une part, les bras complexants ont été diversifiés soit par d'autres motifs monodentes, soit par des motifs potentiellement bidentes, de manière à protéger l'ion lanthanide de la coordination de toute molécule d'eau qui limiterait l'efficacité de luminescence. La mesure des propriétés photophysiques des complexes d'europium ou de terbium a montré que l'introduction d'un bras coordinant phosphonate permettait de diminuer le degré d'hydratation des complexes, et que, par ailleurs, l'introduction d'un bras coordinant picolinate, portant la coordinance du ligand à 10, conduisait à des complexes exempts d'eau. D'autre part, il a été envisagé de modifier les chromophores pyridine de manière à rapprocher la longueur d'onde du maximum d'absorption de la fenêtre de transparence des milieux biologiques, et à augmenter le coefficient d'absorption molaire de l'édifice. Sur la base de travaux précédents, le motif chlorine a été choisi, synthétisé, et fonctionnalisé en vue de son couplage à un des noyaux pyridine du macrocycle pyridinophane.

Lanthanide luminescent complexes are, through their spectroscopic properties, interesting alternatives to organic fluorophores for bioanalyses or cell imaging. Their photophysical properties are in particular used as time-resolved FRET donors that can improve the detection sensitivity and specificity. Recent developments afforded luminescent probes for physiological pH, several endogenous ions or for cell compartments. In this context, developing brighter luminophores is a major stake for a more efficient detection. Following this goal, we envisioned two approaches in order to modify a nonacoordinated pyridinophane platform bearing three pyridine antennae and three acetate pendant arms. First, the pendant arms have been modified, either by other monodentate moieties or by potentially bidentate moieties, in order to shield the lanthanide ion from any water molecule that could limit the luminescence efficiency. Europium or terbium complexes photophysical measurements showed that the introduction of a phosphonate coordinating arm decreased the number of coordinated water…

▼ A range of lanthanide compounds incorporating soft bridging ligands or alkoxide ligands have been synthesised and their magnetic properties investigated. These two classes of compound have shown promise as single molecule magnets but have not been widely studied; this thesis aims to expand on this area of research. Softer bridging ligands are found to slightly increase superexchange interactions between metal centres compared to harder bridging ligands. The introduction to this thesis covers the basic properties of the lanthanides, paying special attention to their chemistry with soft donor ligands and alkoxide ligands. Also included is an introduction to the field of single-molecule magnetism and the role of lanthanide complexes in the study of this behaviour. In Chapter 2, four complexes are reported: the phosphine adducts [Cp'3Ln(H2PMes)] and the phosphide-bridged trimers [(Cp'2)Ln(μ-PHMes)]3 (Ln = Er, Gd). Their structures and magnetic properties are characterised. In Chapter 3, the novel dodecametallic thiolate-bridged lanthanide macrocycles [(Cp'2Ln)3({μ-SCH2}3CMe)]4 (Ln = Dy, Y, Gd) are reported and characterised by X-ray crystallography, NMR spectroscopy and magnetometry. [(Cp'2Dy)3({μ-SCH2}3CMe)]4 is shown to be a single-molecule magnet with Ueff = 69 cm-1. In Chapter 4, the novel thiolate-bridged lanthanide dimers [Cp'2Ln(μ-SCH2{C4H7S2})]2 (Ln = Dy, Y, Gd) are reported, showing sulfur-sulfur bonding leading to ring cyclisation of the bridging ligand [MeC(CH2S)3]3-. These complexes are characterised by X-ray crystallography, NMR spectroscopy and magnetometry. Extra NMR spectroscopic studies were performed to investigate the mechanism of ring closure on the bridging ligand. [Cp'2Dy(μ-SCH2{C4H7S2})]2 is shown to be a single-molecule magnet with Ueff = 87 cm-1. In Chapter 5, four new lanthanide siloxide clusters incorporating alkali metals are reported: the trigonal bipyramidal [Dy2K3(OSiMe3)9]; the octahedral [Dy2K4(OSiMe3)10]; the bi-capped cuboid [Y4K6O6(OSiMe3)12]6-; and the [Dy3K8O3(OSiMe3)12]- 'burger' cluster. All clusters are structurally characterised by X-ray crystallography and [Dy2K4(OSiMe3)10] is magnetically characterised. The synthetic rationalisation for formation of these diverse structures is investigated.

▼ A series of rhodium and iridium organometallic complexes supported by 1-cyclopentadienyl-1,1-bis(4,4-dimethyl-2-oxazolinyl)ethane (MeC(OxMe2)2(C5H4); BoMCp) and 1-fluorenyl-1,1-bis(4,4-dimethyl-2-oxazolinyl)ethane (MeC(OxMe2)2(C13H8); BoMFlu) are described. Metalation of BoMCp readily occurred through salt metathesis from a thallium intermediate or protonolysis with appropriate metal precursors. In contrast, metalation of the more basic BoMFlu ligand required in situ generation of a potassium carbanion with potassium benzyl and salt metathesis with appropriate metal precursors. The piano-stool complexes of BoMCpM (M = Rh or Ir) were unreactive to substitution chemistry and forcing condition required for C–H activation reactions resulted in decomposition of catalysts prior to successful reactions. However, the two-electron oxidation of BoMCpRh(C2H4)2 with Br2 results in BoMCpRhBr2, a new RhIII species. BoMFluM (M = Rh or Ir) complexes readily underwent substitution chemistry. In addition, BoMFluRhL2 (L2 = C8H12 or C16H12) displayed unique electrochemistry of two reversible 1-electron oxidations. The RhII species could be generated in solution with life time greater than 24 hours for L2 = C16H12. A series of lanthanide organometallic complexes, Ln{C(SiHMe2)3}3 (Ln = La, Ce, Pr, Nd) were activated by the abstraction of Si–H with 1 and 2 equivalents B(C6F5)3 to generate Ln{C(SiHMe2)3}2HB(C6F5)3 and Ln{C(SiHMe2)3{HB(C6F5)3}2 respectively. The addition of AlR3 (R = Me or iBu) to Ln{C(SiHMe2)3}3 resulted in the complexation of the weaker lewis acid rather than Si–H abstraction. The hydridoborate alkyl complexes, with AliBu3 co-catalysts, are active in butadiene polymerization. Neodymium and cerium were shown to be the most active and all lanthanides showed a ~50:50 selectivity for cis-1,4:trans-1,4 insertions, with exception of lanthanum which showed a slightly higher selectivity for trans-1,4. Further studies with precatalysts Nd{C(SiHMe2)3}3 indicate a polymerization with living character with respect to reaction time but also showed a dependence of molecular weight on Nd:AliBu3 ratio supporting the proposed chain transfer mechanism. Polymerization in saturated hydrocarbon solvent (heptane) improved cis-1,4 selectivity to nearly 90% with Nd{C(SiHMe2)3}3 pre-catalyst. Nd{C(SiHMe2)3{HB(C6F5)3}2 with 10 equivalents AliBu3 was >95% selective in the polymerization of isoprene to cis-1,4 polyisoprene with good activity in toluene. In contrast, Nd{C(SiHMe2)3}2HB(C6F5)3 was less active in the polymerization of isoprene and displayed a lower selectivity yielding ~40% trans-1,4 polyisoprene. The activation of Nd{C(SiHMe2)3}3 in toluene with different protocols containing the organochloride Ph3CCl were also successful for cis-1,4 selective polymerizations of isoprene. In addition, activation protocols with Ph3CCl improved the cis-1,4 selectivity of polybutadiene to 90% and above. Attempts to utilize Ph3CCl based activations in heptane resulted in highly reactive polymerization ultimately isolating gelled polybutadiene.…

▼ Oxidative stress, or the imbalance of reactive oxidative species and antioxidants, is implicated in a wide variety of physiological functions and diseases. Currently, little is known about the biological concentrations and the exact roles of individual species. In particular, the cellular concentration of hydroxyl radical and the etiology of this reactive oxygen species in disease states are unclear. The photophysical properties of luminescent lanthanide-based imaging agents and the magnetic properties of fluorinated contrast agents make them favorable candidates to monitor oxidative species in biological environments. Luminescent lanthanide-based probes for hydroxyl radical are presented. These probes utilize aromatic acid pre-antennas that sensitize terbium emission upon hydroxylation. The ability of hydroxylated and non-hydroxylated aromatic acids including benzoate, benzamide, isophthalate, isophthalamide, trimesate, and trimesamide to sensitize Tb DO3A was evaluated by time-delayed luminescence spectroscopy. The formation of a weak ternary complex between hydroxytrimeasamide and Tb-DO3A was confirmed by temperature-dependent titrations. The luminescence response of the bimolecular Tb DO3A and trimesamide probe to hydroxyl radical generated by the photolysis of hydrogen peroxide was investigated. The system exhibits excellent selectivity for hydroxyl radical over other biologically relevant reactive oxygen and nitrogen species. Next, fluorinated magnetic resonance imaging contrast agents responsive to hydroxyl radical are described. The 3,5-difluorobenzoic acid probe is water soluble and ratiometrically responds to hydroxyl radical. Upon hydroxylation, a fluoride ion is released. The relative signal intensity of the product and that of the unreacted contrast agent can then be used to monitor the analyte in a ratiometric manner by 19F NMR and 19F MRI. The selectivity of the system towards hydroxyl radical compared to other reactive oxygen and nitrogen species is also measured. Paramagnetic, lanthanide-based contrast agents incorporating the sensing moiety are also evaluated for increased sensitivity of detection compared to the diamagnetic analogs. Additionally, a family of lanthanide-based luminescent complexes based on a macrocyclic core featuring different sensitizing antennas and variable pendant arms are investigated in terms of their biological compatibility. The cellular uptake of Tb-DOTA complexes containing hydroxyisophthalamide (IAM), methoxyisophthalamide (IAM(OMe)), or phenathridine (Phen) antenna were comparable despite their differences in hydrophobicity. The luminescence quenching of Tb-DOTA-IAM(OMe) was also investigated in cell lysate by time-delayed spectroscopy. Pendant arms varying in hydrophobicity and charge were used to evaluate the effect of structural and electronic properties on cellular viability and cell association as measured by a MTT assay and ICP-MS, respectively. Regardless of the amide substituents, complexes based on Tb-DOTAm-IAM(OMe) core exhibited low…

▼ Chemical sensors are important in a wide range of applications. However, there is no commercially available molecularly imprinted polymers (MIPs) based sensor. Thus, the design and development of sensors utilizing imprinting technique have been an area of active research. In Chapter 1, first a brief introduction to imprinting techniques is given. Then we provide a short review of progresses in design of MIPs sensors using multi-functional monomers. Multi-functional monomers (multi-FMs) are high affinity monomers towards target molecules and are able to introduce other functionally active groups for sensing and catalysis. Two classes of multi-FMs will be reviewed and discussed. Then, new advances which we have achieved and strategies which we have developed will be discussed at the end of this chapter. A new method of verifying and characterizing the imprinting efficiency of molecularly imprinted polymers (MIPs) was developed and tested. In the new polar solvent titration (PST) method, a series of MIP and non-imprinted polymers (NIPs) are prepared with increasing concentrations of a polar solvent. The templation and monomer aggregation processes can be systematically disrupted by the polar solvent additives. The changes in the binding capacities of the polymers in each series provide a measure of the relative magnitudes of the imprinting effect and monomer aggregation effects. The new method was tested using three different urea functional monomers that had varying degrees of templation and monomer aggregation self-assembly. Diphenyl phosphate anion was used as template for these polymers. The new MIP characterization method can differentiate differences in binding capacity arising from templation and monomer aggregation. To independently verify the new characterization method, the MIPs were also characterized using the traditional binding isotherm analysis. The two methods appeared to give consistent conclusions. However, the results from the PST method provided more information about the presence and relative magnitudes of the templation and processes that influenced the binding properties of the polymers. In Chapter 3, first we studied the importance of monomer aggregation for molecular imprinting. Monomer aggregation can improve the imprinting effect by suppressing the number of background binding sites. Then, the effects of crosslinking degree were evaluated using MAA and EA9A system. High crosslinking degree was required for imprinting effects. Higher crosslinked polymer exhibits greater imprinting effect. The relative magnitudes of the effect of crosslinking degree are estimated using urea functional monomers and phosphate template system. The effect of decreasing 13% of crosslinking degree was estimated to reduce 24% of the binding… Advisors/Committee Members: Ken D Shimizu.

▼ A range of lanthanide compounds incorporating soft bridging ligands or alkoxide ligands have been synthesised and their magnetic properties investigated. These two classes of compound have shown promise as single molecule magnets but have not been widely studied; this thesis aims to expand on this area of research. Softer bridging ligands are found to slightly increase superexchange interactions between metal centres compared to harder bridging ligands.The introduction to this thesis covers the basic properties of the lanthanides, paying special attention to their chemistry with soft donor ligands and alkoxide ligands. Also included is an introduction to the field of single-molecule magnetism and the role of lanthanide complexes in the study of this behaviour.In Chapter 2, four complexes are reported: the phosphine adducts [Cp’3Ln(H2PMes)] and the phosphide-bridged trimers [(Cp’2)Ln(μ-PHMes)]3 (Ln = Er, Gd). Their structures and magnetic properties are characterised.In Chapter 3, the novel dodecametallic thiolate-bridged lanthanide macrocycles [(Cp’2Ln)3({μ-SCH2}3CMe)]4 (Ln = Dy, Y, Gd) are reported and characterised by X-ray crystallography, NMR spectroscopy and magnetometry. [(Cp’2Dy)3({μ-SCH2}3CMe)]4 is shown to be a single-molecule magnet with Ueff = 69 cm-1.In Chapter 4, the novel thiolate-bridged lanthanide dimers [Cp’2Ln(μ-SCH2{C4H7S2})]2 (Ln = Dy, Y, Gd) are reported, showing sulfur-sulfur bonding leading to ring cyclisation of the bridging ligand [MeC(CH2S)3]3-. These complexes are characterised by X-ray crystallography, NMR spectroscopy and magnetometry. Extra NMR spectroscopic studies were performed to investigate the mechanism of ring closure on the bridging ligand. [Cp’2Dy(μ-SCH2{C4H7S2})]2 is shown to be a single-molecule magnet with Ueff = 87 cm-1.In Chapter 5, four new lanthanide siloxide clusters incorporating alkali metals are reported: the trigonal bipyramidal [Dy2K3(OSiMe3)9]; the octahedral [Dy2K4(OSiMe3)10]; the bi-capped cuboid [Y4K6O6(OSiMe3)12]6-; and the [Dy3K8O3(OSiMe3)12]- ‘burger’ cluster. All clusters are structurally characterised by X-ray crystallography and [Dy2K4(OSiMe3)10] is magnetically characterised. The synthetic rationalisation for formation of these diverse structures is investigated. Advisors/Committee Members: Winpenny, Richard.

▼ Lanthanide ion luminescence can be sensitized when coordinated by a ligand or antenna to give intense and characteristic color emission. Eu(III) and Tb(III) being the most thoroughly studied due to their intense emission in the visible region of the spectrum, the near-infrared emitting ions Yb(III), Nd(III) and Er(III) are gaining interest due to applications in telecommunications and bioimaging. The syntheses of derivatives of pyridine-2,6-bis(oxazoline) and of their lanthanide ion complexes was accomplished. These complexes have potential application as probes in biology and biochemistry, as well as serving as building blocks for polymers for lighting and display applications. Two paths of derivatization were explored, which are the functionalization of the para-position of the pyridine ring and of the á-position of the oxazoline rings. It was found that derivatizing the pyridine-2,6-bis(oxazoline) ligands at the para-position affected the photophysical properties of the resulting complexes very little. Complexes of these ligands display a highly diverse solution and solid state speciation. Among the para derivatives, two water-soluble ligands were described that sensitize Eu(III) and Tb(III) as well as the near-infrared emitting lanthanide ions Yb(III), Nd(III) and Er(III) very efficiently in aqueous solutions. Derivatization of pyridine-2,6-bis(oxazoline) at the oxazoline rings resulted in ligands with different coordination ability, complexes with large ranges in solubility and interesting speciation. The efficiency of the quantum yields was also greatly affected. While moderate to good emission efficiencies were obtained in some cases and significant circularly polarized luminescence was observed in the case of a complex with an asymmetric ligand, another ligand failed to even coordinate to the metal ions.The synthesis and structural and photophysical characterization of the ligands and their lanthanide ion complexes are discussed in detail throughout the presented work.

Les orthophosphates de lanthanides dopés avec des Terres Rares (TR) (LnPO4) sont considérés comme des luminophores intéressants pour des applications optiques. Les luminophores sont des matériaux luminescents qui transforment certains types d'énergie (rayons X, ultraviolet, visible, infrarouge) principalement en lumière visible.

Les échantillons ont été caractérisés par diffraction des rayons X (DRX), spectroscopie infrarouge de Transformée de Fourier, analyse thermogravimétrique (TG), spectroscopie Raman, microscopie électronique à balayage (MEB), microscopie électronique à transmission (MET), et spectroscopie de luminescence (spectres d’émission, d’excitation, rendements quantiques et déclins de fluorescence). En particulier, des nanofils et des nanoparticules de GdPO4:Eu3+, GdPO4:Tb3+ ont été élaborés, ainsi que des poudres de YPO4:Tb3+ avec des phases monoclinique, hexagonale ou quadratique. Il a été mis en évidence une influence significative de la structure cristalline et de la morphologie des luminophores sur leurs propriétés optiques. Des poudres avec une morphologie différente ont été utilisés comme charges pour la préparation de films composites polymère/luminophores. En jouant sur la formulation des orthophosphates et la nature des ions dopants, des luminophores fournissant une lumière proche du blanc idéal sous excitation UV ont pu être élaborés. L’ensemble de ce travail montre clairement les potentialités d’applications de ces matériaux dans des dispositifs basés sur une source d’excitation plasma ou sur la technologie des diodes électroluminescentes.

Rare earth (Re) doped lanthanide orthophosphates (LnPO4) are considered like promising phosphors for optical applications. Phosphors are luminescent materials which convert certain types of energy (X-ray, ultraviolet, visible, infrared) mainly into visible light. In this research Eu3+ (europium), Ce3+ (cerium), Tb3+ (terbium), Er3+ (erbium), Tm3+ (thulium) and/or Yb3+ (ytterbium) doped LuPO4 (lutetium orthophosphate), YPO4 (yttrium orthophosphate), GdPO4 (gadolinium orthophosphate) and/or GdxY1-xPO4 (yttrium-gadolinium orthophosphate) were synthesized by solvothermal process. By varying the synthesis conditions, the crystalline phase, particle size and morphology were controlled by the synthesis conditions these parameters affect the photoluminescent properties. The samples were characterized by means of X-ray Diffraction (XRD), Fourier transform Infrared (FT-IR), Thermogravimetric Analysis (TGA), Raman Spectroscopy, Scanning Electronic Microscopy (SEM),…

▼ Le frittage est une étape clé de l’élaboration des pastilles de combustible nucléaire de type UOx et MOx (oxyde mixte (U,Pu)O2) utilisées dans les réacteurs à eau pressurisée. Le premier stade de ce procédé, qui consiste en l’élaboration de ponts entre les grains et conduit à la consolidation des matériaux, est jusqu’à présent principalement abordé par simulation numérique. Les modèles utilisés pour la description théorique de cette étape du frittage sont alors généralement constitués deux grains sphériques en contact. Afin de réaliser les premières observations expérimentales du stade initial du frittage de matériaux céramiques d’intérêt pour le cycle du combustible électronucléaire et d’en compléter les approches numériques, des poudres d’oxydes de lanthanides (CeO2) et d’actinides (ThO2 et d’UO2) de morphologie contrôlée ont été étudiées par microscopie électronique à balayage en mode environnemental lors de traitements thermiques à haute température (MEBE-HT). Dans un premier temps, des protocoles conduisant à la synthèse de microsphères d’oxydes de lanthanides ou d’actinides ont été développés, et les poudres obtenues entièrement caractérisées. Il a ainsi été possible d’obtenir pour l’ensemble des composés étudiés des systèmes similaires à ceux modélisés. Par la suite, le MEBE-HT a été utilisé comme principal outil d’investigation pour le suivi in situ de ces composés. Ainsi, l’étude de l’évolution morphologique de microsphères isolées a tout d’abord confirmé leur caractère polycristallin. Le traitement thermique conduit alors à une diminution progressive du nombre de cristallites sous l’effet de différents mécanismes (réarrangement mécanique, diffusion) dont l’énergie d’activation a été évaluée. Pour les systèmes constitués de deux microsphères de CeO2 ou de ThO2 en contact, les micrographies collectées ont permis d’observer l’évolution de paramètres tels que la taille du pont, la taille des grains et la distance entre leur centre au cours du traitement thermique. Des procédures de traitement d’images ont ensuite été appliquées pour aboutir à des données cinétiques quantitatives. Les mécanismes mis en jeu, tels que le réarrangement des plans cristallins et la diffusion de matière, ainsi que les énergies d’activation correspondantes, ont en outre été identifiés. De plus, la loi de croissance des ponts, qui permet de décrire les cinétiques d’avancement du frittage, a été utilisée pour déterminer le mécanisme de diffusion prépondérant lors du traitement thermique. L’influence de différents paramètres sur l’avancement du frittage a enfin pu être mise en évidence. A titre d’exemple, l’effet de la polycristallinité des grains sur les mécanismes et les cinétiques de frittage a été étudié en travaillant en parallèle sur des grains poly- et monocristallins, puis en comparant les données expérimentales avec celles issues de modélisation. Enfin, la méthodologie développée pour l’étude de CeO2 et ThO2 a été transposée au composé d’intérêt UO2. Dans ce cas, les données précédemment décrites ont également été complétées par… Advisors/Committee Members: Clavier, Nicolas (thesis director), Podor, Renaud (thesis director).

Le zinc et le cuivre sont à la fois essentiels et toxiques pour les organismes vivants, c’est pourquoi ils sont très finement régulés. Pour comprendre le rôle et les flux de ces métaux, il est nécessaire de pouvoir les imager, notamment à l’aide de sonde fluorescente. Les sondes développées sont basées sur des sites de liaison de métalloprotéines et un complexe de lanthanide pour l’émission en temps résolu.Le principe de la sonde à cuivre(I), inspirée de la chaperonne CusF, repose sur la formation d’une interaction cation-pi entre le cuivre(I) et la chaîne latérale du tryptophane. Cette interaction modifie les propriétés du tryptophane et conduit à l’augmentation de la luminescence du terbium. L’étude du mécanisme spectroscopique a montré que l’interaction cation-pi augmente le croisement intersystèmes et donc la population de l’état triplet du tryptophane, ce qui permet de transférer plus d’énergie au lanthanide. Cette sonde est sélective de Cu+ parmi les cations physiologiques mais s’allume également en présence d’argent(I). Cette sonde a été modifiée dans le but d’améliorer ses propriétés (constantes d’affinité, sélectivité, contraste, longueur d’onde d’émission). L’une des sondes dérivées est capable de différentier entre Cu+ et Ag+, ce qui est unique.Le principe de la sonde à zinc, basée sur une séquence à doigt de zinc, repose sur la modulation du transfert d’énergie entre le lanthanide et son antenne par une modification de la distance. La sonde s’allume sélectivement en présence de zinc. La sonde a ensuite été modifiée, premièrement pour incorporer un second complexe de lanthanide et obtenir une sonde ratiométrique, et deuxièmement pour décaler les longueurs d’onde d’excitation et d’émission respectivement vers le spectre visible et le proche infra-rouge. Sur ce dernier point, une nouvelle antenne a été découverte pour la sensibilisation du néodyme.

Zinc and copper are essential and toxic for living organisms, so they are tightly regulated. To understand, at cellular level, the role of the kinetically exchangeable pool of these metals and their fluxes, we have designed peptidic luminescent probes based on the binding site of metalloproteins and on a lanthanide complex as time-resolved emitting moiety.The copper(I) probe, which is inspired by the chaperone CusF, rely on the formation of a cation-pi interaction between copper and a tryptophan side chain to turn on the luminescence of a terbium ion. Detailed spectroscopic characterizations, including time-resolved spectroscopy, have shown that the cation- pi enhances intersystem crossing and thus population of the tryptophan triplet state, which transfers energy to the lanthanide. This probe is selective for Cu+ among physiological cations but is able to detect silver(I) also. This probe was modified to change its properties (binding constants, selectivity, contrast, emission wavelength). Among derived probes, one of them is able to discriminate between Cu+ and Ag+, a property that has not been reported so far for copper or silver probes.The zinc probe is…

Le ciblage spécifique des infections virales et bactériennes revêt une importance majeure pour le diagnostic précoce de nombreuses maladies. Le galactofuranose (Galf) est absent chez l'homme mais se trouve en tant que fragment de glycoconjugués dans un grand nombre d'agents pathogènes pour les Hommes (Aspergillus, Leishmania, Trypanosoma, Mycobacterium), offrant ainsi la possibilité de cibler ce sucre dans des applications biotechnologiques utilisant des enzymes impliquées dans son métabolisme (UDP-galactose), mutase (UGM), galactofuranosyl transférase (GalfT), galactofuranosidase (Galf-ase). Récemment, la première enzyme spécifique du Galf de Streptomyces spp. et son gène codant ont été rapportés.Ce travail de thèse se concentre sur Galf-ase et se compose de trois parties principales. La première partie concerne la caractérisation de cette enzyme, y compris le sous-clonage, la surexpression, la purification et la cinétique (kcat, KM, kcat,/KM), la détermination de l'activité optimale (pH et température) et de la stabilité au stockage.La deuxième partie consiste à appliquer une technologie d'ingénierie enzymatique (mutagenèse dirigée par site) pour générer des néolectines (protéines de reconnaissance des sucres) à partir du type sauvage. Plusieurs enzymes Galf-ase mutantes ont été surexprimées, purifiées et caractérisées cinétiquement (kcat, KM, kcat,/KM) pour leur potentiel d'utilisation en tant que néolectines et thioglycoligases pour la synthèse de furanothioglycosides.La troisième et dernière partie porte sur les procédures à suivre pour créer des nanoparticules luminescentes destinées à contenir des complexes de lanthanides et à lier les néolectines de Galf-ase à sa surface. Les conjugués luminescents résultants ont été testés en tant que sondes dans l'imagerie optique proche infrarouge de Galf située à la surface de microorganismes.

Specific targeting of viral and bacterial infections is of major importance for early diagnosis of many diseases. Galactofuranose (Galf) is absent in humans but is found as glycoconjugate moiety in a large number of human pathogens (Aspergillus, Leishmania, Trypanosoma, Mycobacterium) thus offering possibilities to target this carbohydrate in biotechnological applications using enzymes involved it its metabolism (UDP-galactopyranose mutase (UGM), Galactofuranosyl transferase (GalfT), Galactofuranosidase (Galf-ase). Recently, the first Galf-specific enzyme from Streptomyces spp. and gene encoding it has been reported.This thesis work focuses on Galf-ase and consists of three main parts. First part is groundwork characterization of this enzyme including subcloning, overexpression, purification and kinetic characterized (kcat, KM, kcat,/KM). Also, determination of optimum activity (pH and temperature) and storage stability conditions.Second part consists of applying enzyme engineering technology (site-directed mutagenesis) to generate neolectins (carbohydrate-binding proteins) from the wild-type. Several mutant Galf-ase enzymes have been overexpressed, purified and kinetically…

Nesse trabalho é apresentado a síntese hidrotermal, estudo estrutural e as propriedades espectroscópicas de três polímeros de coordenação baseados nos lantanídeos (Eu3+, Tb3+ e Gd3+) e o DPA como ligante (DPA= 2,6- dipicolinato). A determinação estrutural do [Eu(DPA)(HDPA)(H2O)2.4H2O] evidencia a presença de clusters de água auto organizados com dímeros e hexâmeros intercalando as diferentes cadeias e o respectivo papel na estabilização da estrutura supramolecular tridimensional. Através dos estudos espectroscópicos foi evidenciado a baixa eficiência quântica (η = 12.7%) como reflexo da larga contribuição das taxas não-radiativas que controlam o processo de relaxação, devido ao acoplamento vibrônico com as moléculas de água. Os polímeros de coordenação [Tb(DPA)(HDPA)] e [Gd(DPA)(HDPA)] são iso-estruturais e permitiram a investigação do processo de transferência de energia. No caso do composto [Tb(DPA)(HDPA)], os dados de luminescência mostraram elevado rendimento quântico da emissão (≈ 50%) devido ao ligante DPA se um bom sensibilizador e a ausência de moléculas de água coordenadas ao metal.

In this work is presented the hydrothermal synthesis, the structural studies and spectroscopic properties of three coordination polymers based on lanthanides ions (Eu3+, Tb3+ and Gd3+) and DPA as ligand (DPA= 2,6- dipicolinate). Structural study of [Eu(DPA)(HDPA)(H2O)2.4H2O] displayed the presence of self-assembled dimeric and hexameric water clusters fit in the linear chains and the respective role on the stabilization of supramolecular strucuture. The spectroscopic investigations show the low quantum efficiency (η = 12.7%) caused by large contribution of non-radiative decay rates governing the relaxation process due to vibronic coupling with water molecules. The coordination polymers [Tb(DPA)(HDPA)] and [Gd(DPA)(HDPA)] are isostructurals and allowed the investigation about energy transfers processes. In the case of [Tb(DPA)(HDPA)] compound, the photoluminescence data shown the high quantum yield of emission (≈ 50%) due tho the DPA ligand to be a good sensitizer and the lack of water molecules coordinated directly to metal.

▼ The aims of this thesis were twofold: A) To use high internal phase emulsion (HIPE) templated materials to produce a chromatographic stationary phase for the size separation of engendered nanoparticles (NPs). B) To produce well characterised lanthanide doped polymer NPs with a potential use as analytical standards.Initially, silica materials were prepared from oil-in-water HIPEs by a two stage acid/base catalysed sol gel process. As well as presenting the expected macroporosity typical of HIPE templated materials, it was also found that micro- and meso-porosity could be influenced by surfactant choice and reaction with iron (III) chloride or copper (I) chloride which had been included in the HIPE. However, the resulting silica materials were deemed inappropriate for the desired chromatography. Monolithic columns were prepared from HIPE templated polymers (polyHIPEs) and incorporated into a HPLC system. Poly(styrene-co-divinylbenzene) and poly(ethylene glycol dimethacrylate) polyHIPE columns were able to separate sub-micron polystyrene latexes, detected by UV absorption, and dysprosium doped polystyrene latex particles and gold nanoparticles detected by inductively coupled plasma mass spectrometry (ICP-MS).Dysprosium, gadolinium and neodymium doped polystyrene NPs were prepared by micro-emulsion polymerisation. Particle size was controlled (over a 40 – 160 nm range) by tailoring of surfactant and initiator concentrations. Particles were characterised by dynamic light scattering, differential centrifugal sedimentation, transition electron microscopy and hydrodynamic chromatography (HDC)-ICP-MS. Also, particle surface change, lanthanide content and solids content were analysed. The latter two appear related to particle size.As far as the author is aware there are no cases of the use of polyHIPE columns size separation in the literature. Nor are there any cases of encapsulation of metals within polymer nanoparticles by micro-emulsion polymerisation reported. Advisors/Committee Members: Budd, Peter.
