▼ This thesis focuses on the synthesis of functional materials composed of ligands that possess a methylene hinge – a flexible link between two coordinating groups – and the capacity to form a six-membered chelate ring with transition metals that moderates structural flexibility. A significant portion of this work characterises and explores the properties of a class of functional materials called metal-organic frameworks (MOFs). By utilising methylene-hinged ligands, MOFs are designed that contain intrinsic flexibility and consequently interesting guest exchange and gas adsorption properties. The first methylene-hinged ligand described, di-2-pyrazinylmethane, exhibited an exceptionally rich coordination chemistry with silver(I). Appropriate conditions led to the crystallisation of three isostructural 3-D silver(I) MOFs with large 1-D channels. Although these materials lacked permanent porosity, they possessed the ability to undergo guest-induced structural contraction and expansion. This remarkable solid-state behaviour was related to the chemistry of the guest. The theme of structural flexibility is continued in subsequent chapters which describe the structural flexibility and gas adsorption properties of several MOF materials composed of Cu(II), Co(II), Ni(II), or Mn(II) and the ligand bis(4-(4-carboxyphenyl)-1H-pyrazolyl)methane or bis(4-(4-carboxyphenyl)-3,5-dimethyl-1H-pyrazolyl)methane. Some of the work reported in chapter 3 that deserves particular attention is the exceptional CO₂/N₂ selectivity of a Cu(II) MOF. This material undergoes post-synthetic structural contraction to achieve pore dimensions capable of discriminating between CO₂ and N₂ based on their respective kinetic diameters. Another noteworthy material is described in chapter 4; a flexible Mn(II) MOF capable of quantitative post-synthetic metal binding with preservation of single-crystallinity. The framework flexibility of this material allowed elucidation of the primary coordination sphere of the grafted metal ion and subsequent solid-state transformations by X-ray crystallography. A large portion of this thesis demonstrates and emphasises the positive impact of structural flexibility in MOFs as functional host materials. Chapters 5 and 6 describe methylene-hinged compounds from the viewpoint of synthetic precursors to more complex ligands that contain a fused pyrazino[2,3-b]indolizine or indolizino[2,3-b]quinoxaline core. The synthesis, metal complexes, and corresponding solid-state structures of a series of these ligands are described.

▼ Porous metal-organic materials (MOMs) are assembled through coordination between two types of building units, metal or metal-containing nodes and organic linkers. Metal-organic frameworks (MOFs) have 3-D infinite structures and are especially known for high porosity and enormous surface area, leading to diverse applications such as selective gas separation, gas storage and catalysis. In contrast, metal-organic polygons/polyhedra (MOPs) as discrete molecular coordination assemblies are soluble in certain solvents, allowing us to study their solution-chemistry. In the first project, a microporous MOF with 1-dimensional (1D) bridging helical chain secondary building units (SBUs) shows facile transition from micro- to mesoporosity upon activation conditions. The quickly activated MOF shows permanent microporosity while the slow removal of coordinated aqua ligand results in formation of the mesopores in the microporous MOF. Second, a strategy to introduce not only the functional groups but also functionalized meso-cavities into microporous MOFs through metal-ligand-fragment coassembly has been studied. With this functionalization, the interior of the MOFs can be tuned by a wide range of functional groups on the ligand fragments, including polar and ionic ones. Depending on the functional groups on the ligand fragments, the introduced cavities can be extended to mesopores in a controllable manner. Third, a MOF constructed from dicopper paddlewheels and a predesigned ligand bearing carboxylate, pyridine, and amide groups enables selective adsorption of CO2 over CH4 and high H2 adsorption. The cooperative catalytic activity in a tandem one-pot deacetalization-Knoevenagel condensation was demonstrated. In the fourth and fifth section, an optically and thermally switchable azobenzene was introduced into a MOF and MOPs, respectively. The freshly synthesized MOF adsorbed a significant amount of CO2. Upon light irradiation, the adsorbed gas molecules were squeezed out of the MOF due to the change of conformation of the azobenzene groups inside the pores. The adsorbent returned to its original state when allowed to stay with gentle heating. In addition, solubility of srMOPs was optically controlled by trans-cis isomerization of the azobenzene moieties. Interestingly, guest molecules were trapped during cis to trans isomerization and released in the trans to cis conversion. This srMOP can be applied to uses requiring stimuli responsive capture and release of guest molecules, such as in controlled drug delivery systems. Finally, an organic linker with multiple conformations was used to synthesize both single and core-shell molecular squares, whose formations were controlled by reaction temperatures. Intriguingly the core-shell structure assembly was successfully employed as a template to prepare a heterobimetallic assembly, in which the metal substitution occurred exclusively in the core. This work might pave the way for the exploration of enzyme-mimicking molecular catalysts.

▼ The theme of this work is the observation and understanding of the effects of pore functionalization on adsorption properties of stable Metal-Organic Frameworks (MOFs). Over the first two sections of this work, sets of materials with representative pore sizes and functional groups are studied for adsorption properties. Observed trends are used to identify the best pore properties achievable via functionalization for adsorption systems. The third section of this work provides perspective on MOF materials and proposes target pore features for an efficient adsorbent for carbon dioxide capture from flue gas. First, the highly stable UiO-66 series of materials was selected for a pure-component adsorption study. The selectivity and capacity for CO2 can be best enhanced with the smallest, most polar functional group, such as an amino group, but significantly enhance water adsorption. Large, non-polar groups do not yield a completely hydrophobic material, but may be useful for humid gas separations as pore filling with water is inhibited. Next, a breakthrough study was conducted using CO2:CH4 and CO2:N2 mixtures on a set of stable MOFs. UiO-66-NH2 and UiO-66-DM, where DM=dimethyl, outperform predictions based on published isotherms and have dynamic CO2:CH4 selectivity comparable to zeolite NaY. UiO-66-DM may be a good candidate for further study due to the combination of partial hydrophobicity and good selectivity. Finally, by combining a review of literature with observations made in this work, a perspective on MOFs as efficient humid gas separation materials is provided. The presence of water vapor prevents use of current high performance adsorbents, but several MOF pore features show promise for these separations. The designable nature of MOFs allows for targeted design of size-matched pores and single-molecule traps which can selectively or cooperatively adsorb CO2 in the presence of water. Also, many MOF materials would be well suited for advanced pressure swing adsorption cycles and engineered sorbents, which enables greater material utilization and system efficiency.

▼ The research presented in this thesis investigates the use of metal carboxylates as permanently porous materials called metal-organic frameworks (MOFs). The project has focused on three broad areas of study, each which strives to develop a further understanding of this class of materials. The first topic is concerned with the synthesis and structural characterization of MOFs. Our group and others have found that the reaction of metal salts with carboxylic acids in polar solvents at elevated temperatures often leads the formation of crystalline MOF materials that can be examined by single crystal X-ray diffraction. Specifically, Chapter 2 reports on some of the first examples of magnesium MOFs, constructed from formate or aryldicarboxylate ligands. The magnesium formate MOF, [Mg3(O2CH)6] was found to be a permanently porous 3-D material capable of selective uptake and exchange of small molecules. Once the synthesis and structures of some of these materials was known, their physical properties were studied. The magnesium formate MOF, [Mg3(O2CH)6], was found to be permanently porous and able to reversibly adsorb both N2 and H2 gas. Furthermore, the material was also capable of taking up a variety of organic molecules to form new inclusion compounds that were characterized by XRD studies. Size exclusion was shown for cyclohexane and larger molecules. Chapters 3, 5, and 6 attempt to build off of the synthetic findings reported in Chapter 2. Specifically, the ability of these materials to take up guest molecules is expanded by the attempted synthesis of porous, homochiral MOFs using enantiopure carboxylic acids in the synthesis. It was found that under the appropriate synthetic conditions, both L-tartaric acid and (+)-camphoric acid were robust linkers for the formation of homochiral MOFs. Of the compounds synthesized, the most interesting were the set of compounds, [Zn2(Cam)2(bipy)ÌÄ"¡3DMF] and [Zn2(Cam)2(apyr)ÌÄ"¡2DMF]. These compounds formed isoreticular cubic networks in which the pore size was dependent on the size of the linker molecule (bipy or apyr). Additonally, the compounds [Zn2(Cam)2(bipy)ÌÄ"¡3DMF] and [Zn2(Cam)2(apyr)ÌÄ"¡2DMF] were found to be capable of guest exchange. Due to their chiral nature, these materials were screened for the enanatioselective separation of racemic alcohols. No selectivity was seen with either MOF, likely owing to factors such as large pore size and disorder in the chiral camphorate ligand. [Zn2(Cam)2(bipy)ÌÄ"¡3DMF] contained large voids and preliminary studies showed that free-radical polymerization of methylmethacrylate could take place within the channels of the material. The amino group of the apyr ligand in [Zn2(Cam)2(apyr)ÌÄ"¡2DMF] was able to be functionaled with acetaldehyde by treatment of the porous MOF with the bulk organic reagent. A further area of study detailed in this work deals with a central question in MOF chemistry, concerning the assembly process of these extended materials from solution. Chapter 3 reveals that the trimeric… Advisors/Committee Members: Kenneth W. Henderson, Committee Chair, Slavi. C. Sevov, Committee Member, Robert Nelson, Committee Chair, W.

▼ A growing field of research has evolved around the design and synthesis of a variety of porous metal-organic framework (MOF) materials. Some of the most promising areas for which these materials are potentially useful candidates include gas-separation, heterogeneous catalysis, and gas-storage, and all of these applications involve placing the MOF under pressure. There is clearly a need to understand the structural response of MOFs to applied pressure. Nevertheless, hitherto there are very few published investigations dedicated to determining the behaviour of porous hybrid materials under pressure. Through the use of high-pressure single-crystal X-ray diffraction studies, a series of MOF materials have been studied. Here we present the effect of pressure on a series of MOFs. In chapter 2, the effect of pressure on the prototypical MOF called MOF-5 was studied experimentally from ambient pressure to 3.2 GPa. Here, application of pressure was driven by the hydrostatic medium being forced into the pores of the MOF, which altered the mechanical properties of MOF-5, in particular, medium inclusion delayed the onset of amorphization. Complementary computational analysis was also performed to elucidate further the effect of medium inclusion on compressive behaviour. Detailed structural data was also collected as a function of pressure on the MOF Cu-btc. Application of pressure caused solvent to be squeezed into the pores (like MOF-5) until a phase transition occurred, driven by the sudden compression and expansion of equatorial and axial Cu–O bonds. High-pressure post-synthetic modification of a MOF is reported for the first time. On application of pressure of 0.2 GPa to the Cu-based MOF called STAM-1, a ligand exchange reaction takes place resulting in a change in pore size, shape, and hydrophilicity of the resulting pores. Here, we also demonstrate the ability to force hydrophilic molecules into hydrophobic pores using pressure, counteracting the hydrophobic effect. A high-pressure combined experimental and computational study has been carried to probe the effect of pressure on ‘breathing’ mechanisms in a zeolitic imidazolate framework (or ZIF) called ZIF-8. The penetration of guest molecules and the accommodation of pressure are shown to be inextricably linked to the rotation of methylimidazolate groups in the structure. Finally, the application of pressure to the MOF Sc₂BDC₃ and the nitro functionalized derivative Sc₂(NO₂-BDC)₃ was also studied. Here, the effect of chemical modification of the organic ligand, whilst maintaining framework topology, has been investigated as it pertains to compressibility. Directionality of compression is observed and this is rationalized with respect to the framework topology and medium inclusion/exclusion.

▼ Flexible Metal-Organic frameworks that exhibit a gate-opening (GO) adsorption mechanism have potential for gas separations and gas storage. The GO phenomenon occurs when molecular gates in the structure expand/contract in response to the activation/de-activation of a system variable e.g. temperature, pressure or gas. Sharp discontinuities in the isotherm leading to S-shapes and large adsorption-desorption hysteresis are typical of this phenomenon. This study investigates the kinetics and thermodynamics of the GO behavior by combining adsorption measurements and analytical modeling of adsorption kinetics and capacity as a function of adsorbate, GO pressure, and temperature. Basic understanding of GO mechanism will help harness GO-MOF‘s as adsorbents for gas separations and storage. Experiments were performed on two precharacterized MOFs with verified GO behavior. These are (1) Zn2(bpdc)2(bpee), which expands from a relative amorphous to crystalline structure and (2) Cu[(dhbc)2(4,4‘-bpy)]H2O, a mutually interdigitated 2-D structure (bpdc = biphenyldicarboxylate, bpee = 1,2‐bipyridylethene; DMF = N,N-dimethyl formamide, dhbc= 2,5-dihydroxybenzoic acid, bpy=bipyridine). Both sub- and super-critical adsorption data were collected using three adsorption units: a standard low-pressure volumetric adsorption unit, a commercial high-pressure gravimetric analyzer and a custom-built high-pressure differential volumetric unit. Collected laboratory data were combined with published adsorption rate and isotherm data for analysis to broaden the range of data collection. The accuracy of the high-pressure differential unit was improved by over 300-fold by changing analytical methods of processing data to establish a reliable null correction. A pronounced effect of the allowed experimental time was found at cryogenic temperatures on (1). Tightening the stability criteria used by the adsorption equipment to determine equilibration increased the experimental time from the order of minutes to >60 hours, and this in turn, led to a ~300 fold increase in capacity, convergence of capacities at similar reduced temperatures (critical temperature being the reducing parameter), discontinuities in the isotherms, lowering of gate-opening pressures, changes in the isotherm shapes as well as width of hysteresis loops. Although an experimental time effect was also seen for H2 adsorption at 77K, H2 showed no discontinuity in the adsorption isotherm, adsorption-desorption hysteresis was much less pronounced, and equilibration required significantly less time. The significant difference in rates of adsorption by different gases was attributed to an activated configurational diffusion regime in which the diffusing species moves through a corrugated surface potential when the diameter of the adsorbate approaches that of the pore. A concentration-dependent diffusion model coupled with insufficient equilibration time provides an alternate explanation to describe the stepwise adsorption behavior in GO-MOFs and the changes in capacities. A sigmoid shape of…

▼ As the culprit of global warming, the emission of carbon dioxide has gradually become one of the most severe and environmental concerns haunting the human beings for several decades. These emissions are mainly generated from the combustion of fossil fuels - the main energy resources for our daily life, economic growth and industrial development (Chen, Kim, & Ahn, 2012). In order to prevent global warming deteriorating, it is urgent for all humankind to seek effective and feasible methods to capture and store carbon dioxide. Undoubtedly, Porous solid materials such as metal-organic frameworks (MOFs) are very promising candidates for this application due to their extraordinary capability of capturing Carbon dioxide and excellent regenerative ability as compared to other materials. The study is to explore the feasibility of a method to synthesize layered MOFs by introducing new organic linkers into amorphous state precursors.; Recently, metal-organic frameworks (MOFs) composed of metal ions and organic linkers to form various dimensional structure, emerge as the cost-effective materials for carbon dioxide capture and separation. Due to the desirable pore property like high surface area, excellent uniformity, and tunable pore size, the MOFs attract a great deal of researchers fixating on solving carbon dioxide issue. On the one hand, by replacing the original organic linkers with the specific organic linkers, the MOFs properties can be modified to make the particular application in the certain field. On the other hand, the selection of multiple metal ions such as some transition metals also make the configurations of MOFs diverse.; The purpose of the study is to search for a feasible and cost-reducing process to form new metal-organic frameworks (MOFs) by hypothetically introducing new organic linkers such as BPBDC (Biphely-4,4-Dibenzoic acid), BDC (Terephthalic acid), DABCO (1,4-diazabicyclo[2.2.2]octane) into the amorphous state of original metal-organic frameworks. Meanwhile, by altering the reaction conditions (reaction time, reaction temperature, the polarity of the solvent, sample preservation state, air condition, the number of organic linkers), the crystallinity and morphology of new layered MOFs can be optimized in the study.

▼ Metal Organic Frameworks (MOFs) are highly porous, crystalline frameworks composed of an organic linker and a metal oxide cluster. Covalent Triazine Frameworks (CTFs) are a subclass of MOFs and similarly are highly porous crystalline frameworks, but unlike MOFs, are composed of purely organic building units. Since the initial reports of a successful synthesis and characterization of MOF-5 in 1995, the interest in these frameworks has exploded. The ability to design the MOF properties and functionality by simply selecting the starting precursors make MOFs optimal materials for a multitude of fields. However, even with all of the research being conducted, there are many MOF applications yet to be discovered. In the first part of this thesis we explore the application of MOFs as templates for the synthesis of metallic nanostructures based on the size and the shape of the MOF pores. The limitless number of MOF structures with different pore shapes and sizes allow for the synthesis of nanostructures with any desired shape or size. It is shown that by using MOF-545 with one dimensional pores, well aligned, ultra-thin gold and platinum nanowires are grown. The nanowires inside the MOF pores are confirmed by imaging the focus-ion beam cross-section of the metal loaded MOF-545 using a transmission electron microscope. In the second part of this thesis, the use of MOFs as a precursor to fabricate nitrogen and metal co-doped carbons is discussed. MOF-545 is an excellent precursor for one-pot synthesis of metal and nitrogen co-doped carbon wires. Two different annealing methods are studied, either under pure argon or argon mixed with air impurities, and the resulting carbon wires are tested as an electro-catalyst for oxygen reduction reaction (ORR). Surprisingly, the air treated carbon wires show much higher ORR activity, comparable to that of platinum in basic electrolyte. Finally, the last part of this thesis will discuss controlling the surface area and porosity of carbon frameworks fabricated from CTFs. By using three different precursors, 12 carbon networks are synthesized and analyzed for porosity, surface area and capacitance. By varying the precursor composition and ratio, as well as the temperature, we are able to control the average pore size distribution between 1-17 nm, while the samples treated at 900ï¿½C show the best capacitance of 130 F/g.

▼ The focus of this research is to investigate the synthesis of novel mixed linker metal-organic frameworks (MOFs) composed of pyrozolate and imidazolate based linkers through a mixed-ligand co-assembly process. In MOF synthesis, judicious selection of metal containing nodes combined with symmetric ligands can provide a modicum of predictability to the ultimate structure of the framework. Traditionally, carboxylate ligands have been heavily utilized for the construction of porous materials; however, nitrogen based ligands have not been as frequently used. Of the MOF family, zeolitic imidazolate frameworks (ZIFs) have been the most widely studied material composed of nitrogen-based ligands; however, these frameworks have primarily been constructed from only tetrahedral building units with zinc and cobalt metal nodes, which severely limits the diversity of such frameworks. After an introduction of MOF materials and high throughput synthesis, we investigate the synthesis of new MOFs through mixed-linker co-assembly. An uncommon Pyrazole3Cu3OL3 building unit is observed in two new MOFs, PCN-351 and PCN-352. The first MOF, PCN-351 exhibits three distinct channels and small pores. PCN-352 is composed of molecular polyhedral cages and exhibits enhanced porosity and surface area. Additionally, high-throughput synthesis will allow for the systematic study of MOF formation under varying reaction conditions. Structural predictability is often limited, due to the many kinetic and thermodynamic factors that contribute to MOF formation including metal selection, ligand selection (connectivity, bonding angles, solubility, etc.), solvent selection, modulating agents, and pH values. This project will use a Chemspeed SLT-Swing robotic synthetic platform to exploit combinatorial chemistry methods in MOF synthesis. Utilizing the robotic platform, solvothermal reactions can be screened to optimize MOF formation through selection of solvent, determination of optimal reactant concentrations (metal to ligand ratios, modulation reagents, etc.), and determination of appropriate reaction temperature. This project builds upon the previously discover mixed-linker MOFs using ligand co-assembly. Ligand extension has often been used to study reticular chemistry for the formation of MOFs with enhanced porosity. Herein, we will explore the effect of linker length in the formation and symmetry of MOFs. A series of MOFs have been synthesized using the mixed linker co-assembly procedure and exhibit tuneable surface area and porosity. Finally, we explore the use of porphyrin linkers in the synthesis of mesoporous MOFs (PCN-228, PCN-229 and PCN-230). Porphyrin linkers are highly conjugated systems that have been shown to eliminate interpenetration of MOFs. In this work a series of elongated porphyrin linkers with Zr6 metal nodes have been studied and show enhanced porosity and stability. We build upon the synthesis of porphyrin MOFs, using high-throughput synthesis and the mixed ligand co-assembly method, to construct a copper based porphyrin MOF… Advisors/Committee Members: Zhou, Hong-Cai J (advisor), Dunbar, Kim R (committee member), Banerjee, Sarbajit (committee member), Sue, Hung-Jue (committee member).

▼ Metal-organic frameworks (MOFs) are crystalline materials composed of metal clusters and organic ligands. MOFs that exhibit photoluminescence are promising materials for a broad range of applications. Due to their structural tunability and crystalline nature, luminescent MOFs also provide an excellent platform for studying structure–property relationships of materials. The photophysical properties of three anthracene-dicarboxylic acids – 1,4-anthracene dicarboxylic acid (1,4-ADCA), 2,6-anthracene dicarboxylic acid (2,6-ADCA) and 9,10-anthracene dicarboxylic acid (9,10-ADCA) – were studied in a series of polar aprotic solvents using steady-state absorption, steady-state emission spectroscopy and time-correlated single photon counting (TCSPC) emission lifetime spectroscopy. The addition of carboxylic acid functional groups on the anthracene ring alters photophysical properties to varying degrees depending on the location and protonation state. Density functional theory (DFT) calculations reveal that the lowest-energy ground-state structures of both 2,6-ADCA and 1,4-ADCA have dihedral angles between the carboxylic acids and aromatic planes of θ = 0°, while the same dihedral angle increases to θ = 56.6° for 9,10-ADCA. Time-dependent DFT calculations suggest that the carboxyl groups of 1,4-ADCA and 2,6-ADCA remain coplanar with the anthracene ring system in the excited state. In contrast, the calculations reveal significant changes between the ground and excited geometries for 9,10-ADCA and puckering of the anthracene moiety of is observed. The three anthracene dicarboxylic acids were then incorporated into zirconium-based MOFs. The MOF structures were characterized using powder X-ray diffraction (PXRD) and scanning electron microscopy (SEM). The steady-state absorption and emission spectra as well as the fluorescence lifetimes of the MOFs were compared to that of the corresponding ligand in solution. The MOFs comprising 9,10-ADCA and 2,6-ADCA formed highly crystalline octahedral shaped crystals and were found to be isostructural with the well-known UiO-66 and UiO-67 frameworks. However, incorporation of the 1,4-ADCA ligand resulted in large rod-shaped crystals. The absorption spectra of the MOFs are broadened and redshifted compared with that of the corresponding free ligands. The emission spectra of the MOFs constructed from 9,10-ADCA and 1,4-ADCA display emission bands that resemble that of the free ligand in acidic solutions, but are slightly broadened and redshifted in the MOF. Little difference is observed between that of 2,6-ADCA within the MOF and in acidic solution. The broadening and redshift observed in the absorption and emission is indicative of intermolecular interactions between anthracene units and/or with the Zr4+ clusters. The fluorescence lifetimes measured for the anthracene-based MOFs show a long component, comparable to the lifetime of the free ligand, along with shorter component. This may also suggest intermolecular interactions between chromophores in the MOFs. Altogether, derivatization of… Advisors/Committee Members: Morris, Amanda (committeechair), Morris, John R.

▼ The objective of this work was to develop a molecular simulation method with the capacity to represent the synthesis of metal-organic framework (MOF) structures to the extent of being able to accurately predict the MOF structures that form under specified reaction conditions. MOFs are a class of porous, crystalline solids composed of metal-ion vertices coordinated by organic linker molecules. MOFs are created in a self-assembly process in which the building blocks (reactants) retain their integrity. Under different experimental synthesis conditions, a particular combination of building blocks can react to form differing MOF structures. The structure of MOFs confers a large degree of tunability, allowing almost limitless potential for the materials to be designed with the capacity to fulfil the requirements of a specific application. Consequently, MOFs have shown promise for a variety of applications including gas storage, separation and catalysis. Thus, the ability to accurately predict the MOF formed by specifying reaction parameters such as temperature, pH and the concentrations of reactants has great potential because, upon identification of a promising hypothetical structure for a particular application, the synthesis conditions ascertained via the simulation method could be used as the basis for the determination of an experimental synthesis procedure. In addition, a simulation method with the capacity to predict MOF structures affords the opportunity to gain a fundamental understanding of the influence of the experimental synthesis conditions on the structures formed, so as to enable progress towards the rational design of MOFs. In this work, the experimental synthesis of MOFs via self-assembly is modelled using a kinetic Monte Carlo approach. Ideally, simulation of the self-assembly of the building blocks would be modelled atomistically with all atoms in the reactant and solvent molecules represented explicitly. However, due to the prohibitive computational requirements of such a simulation, in this work a “potential-of-mean-force” (PMF) approach was used to represent the solvent implicitly by encompassing the solvent-mediated behaviour in the interactions between building blocks, thereby reducing the computational cost. The PMF approach to the implicit representation of the solvent involved the utilisation of effective pairwise interactions between the constituents of the reactant species. Following extensive testing to ensure that the explicit-solvent behaviour of the reactants could be replicated using the PMF method, this approach allowed computationally efficient implicit-solvent simulations of the synthesis of MOF materials to be performed. Thorough assessment of a method developed to simulate the synthesis of MOFs required investigation of a system which, under different reaction conditions, forms differing structures. In this respect, the cobalt succinates represent an unparalleled test because under different reaction temperatures, reactant concentrations, pH and reaction time, seven different phases…

▼ El trabajo descrito en esta tesis se enmarca en el ámbito de los polímeros de coordinación (PC). Estos sistemas representan un área importante dentro de la Química de los Materiales, siendo principalmente interesantes sus aplicaciones en catálisis, electrónica y óptica. Su origen data de principios de los años 60, donde se produjo la primera revisión de estructuras de compuestos inorgánicos que formaban cadenas.1 Los PC están formados por ligandos orgánicos y metales enlazados por enlaces de coordinación que se extienden infinitamente en 1, 2 o 3 dimensiones. En cuanto a su versatilidad química, las estructuras y propiedades varían en función de los metales o ligandos utilizados. Así pues, la variable naturaleza de los ligandos orgánicos junto con la diversidad de metales posibles dan lugar a un abundante número de potenciales topologías y arquitecturas que pueden ser ingeniadas mediante un diseño químico apropiado. Los PC dan lugar a redes regulares con una tremenda estabilidad química, aunque también pueden formar sólidos flexibles que responden a estímulos externos de interés. Uno de los hallazgos más interesantes dentro de este campo de los PC ha sido el hecho de constatar que muchos PC con estructuras flexibles presentan cierto dinamismo2 que está directamente relacionado con la flexibilidad del ligando3 o con la habilidad que poseen los centros metálicos de coordinación para aceptar/intercambiar moléculas coordinadas. Estos materiales dinámicos son capaces de desarrollar cambios estructurales de forma reversible, siendo excepcionalmente útiles para la preparación de sofisticados materiales multifuncionales con propiedades físicas modulables. Esto resulta de particular interés en materiales magnéticos, ya que sus propiedades físicas son extremadamente sensibles a pequeños cambios estructurales provocados por un estímulo externo. Los polímeros magnéticos de coordinación (PMC) son una clase de materiales magnéticos especialmente interesantes debido a sus potenciales aplicaciones en el desarrollo de materiales magnéticos de baja densidad, sensores magnéticos y materiales inteligentes o multifuncionales.4 El magnetismo tiene su origen en los portadores de espín, que son centros metálicos paramagnéticos o ligandos orgánicos radicales. Dependiendo del origen del acoplamiento entre estos portadores, podemos distinguir entre dos tipos diferentes de PMC: i) los PMC que presentan ordenamiento magnético; y ii) los PMC basados en complejos de transición de espín.

▼ With carbon dioxide emissions from the combustion of coal, oil and natural gas comprising nearly 80% of worldwide emissions, and with total global emissions on the rise, the need for high-performance, low-cost sorbent materials is ever growing. Solids adsorbents have garnered much interest as CO2 adsorbents as they offer the ability to reduce the regeneration penalty that plagues modern amine scrubbers due to their much lower heat capacities. One class of solid adsorbents is metal-organic frameworks (MOFs). These inorganic-organic hybrid materials have shown promise for a wide range of applications in adsorption separations and catalysis, owing to their high surface areas, vast selection of metal sources and organic linkers, and tunable chemical properties. The development of the chemical intuition necessary for targeted experimental synthesis of novel structures would revolutionize the field of adsorption and allow access to the enormous array of chemical and structural properties of these materials. In this dissertation, an investigation on the effects of synthesis solvent and acid gas adsorption on the structure and gas adsorption properties of several MOF structures was performed. The study of MIL-53(Al) revealed that synthesis solvent plays an important role in the structure and CO2 adsorption properties of the framework, a finding that can be leveraged for modification of these properties for specific applications. A comprehensive investigation of the effects of acid gas adsorption on MIL-125 allowed the determination of the degradation mechanism in the presence of water and SO2. This study provided an experimental and computational pathway for the determination of acid gas degradation effects in other MOFs. Finally, a mixed MgAl oxide was explored as a beneficial binding material to increase the adsorption of composites formed with UiO-66 and provide an avenue for future studies of increased adsorption in MOF composites.

▼ Metal–organic frameworks (MOFs) are newly emerging inorganic–organic hybrid porous materials with diverse crystalline structures, high surface areas, and tunable pores. This dissertation primarily focuses on design and synthesis of MOFs as well as the development of synthetic methodologies to target stable MOFs with desired functionalities. In the second section, a linker exchange strategy was developed as a route to functionalize a mesoporous MOF, PCN-333, through thermodynamic control. This strategy allowed a facile incorporation of a variety of functional groups into the mesoporous MOF without compromising integrity of the parent MOF. In the third section, a dual-exchange method was studied using a sequential linker exchange and metal metathesis on PCN-333(Fe) to achieve a chemically robust mesoporous Cr-MOF with desired functional group. Dual exchange showed the potential of this method to be a general approach to highly stable Cr-MOFs with desired functional groups upon selection of appropriate MOF template. In the fourth section, a new Zn-MOF, SO-PCN, was designed and synthesized as a host of two dye linkers. SO-PCN showed energy transfer between the 2D porphyrinic photosensitizer layer and the photochromic switch pillar in the framework. Using photochromic reaction of the linker in SO-PCN, a reversible control of singlet oxygen generation was demonstrated. The catalytic activity of SO-PCN was also studied for photooxidation of 1,5-dihydroxynaphthalene. In the fifth section, a new synthetic strategy to incorporate multiple functional molecules within the MOF nanoparticles was demonstrated for control of 1^O2 generation for PDT. This strategy was developed to improve several inherent limitations from SOPCN in the previous section. First, a Zr-MOF nanoplatform showed much improved stability in aqueous media, compatible under physiological conditions. This strategy allows for tuning of the ratios between the photosensitizer and the switch molecule within the Zr-MOF nanoparticles, thus enabling maximization of the 1^O2 generation controllability. As a result, MOF nanoparticle formulation showed an enhanced PDT efficacy with superior 1^O2 control compared to that of homogeneous molecular analogues. In the sixth section, size-controlled synthesis of Zr-based porphyrinic MOF nanoparticles was studied through a bottom-up approach. The study provided mechanistic insights about the size control of the porphyrinic Zr-MOF nanoparticles. Size-dependent cellular uptake and ensuing PDT efficacy were also investigated to optimize the size of the MOF nanoparticles for PDT. Additionally, folic acid modification on the Zr6 node in the MOF showed further enhanced PDT efficacy via active targeting, demonstrating multifunctional MOF nanoplatform. In summary, methodologies to allow functionalization of highly stable MOFs have been designed and studied. Conceptual utilizations of MOF nanoparticles for biomedical applications have also been demonstrated with stable MOF nanoparticles, showing the advantages of the MOF… Advisors/Committee Members: Zhou, Hongcai (advisor), Balbuena, Perla (committee member), Hilty, Christian (committee member), Wooley, Karen (committee member).

▼ Considerable efforts have been made to develop the supramolecular systems being capable of selectively binding and recognizing specific chemical species. Within this context, particular has been put towards nuclear waste remediation, environmental chemistry, and biology. Calix[4]pyrroles are non-conjugated tetrapyrrolic macrocycles capable of binding anions and neutral substrates via concerted and directional hydrogen bonding. Moreover, functionalization of the calix[4]pyrrole meso position allows the incorporation of additional binding sites for both cations and anions. Due to the ease of preparation and functionalization, elaborated calix[4]pyrroles have been employed as various anion and ion pair receptors as well as potential extractants for species present in high-level liquid waste (HLLW) and transporters for biological important ions in connection with therapeutic aims. These studies reported herein are primarily focused on the discovery in meso-substituted calix[4]pyrrole-functionalized extended molecular systems and applications for environmental concerns. Chapter 1 provides a brief overview regarding the historical perspective and inherent properties of calix[4]pyrroles, as well as outlines recent contributions for capturing, extracting and sequestering chemical species with environmental concerns. Chapter 2 describes the extraction of the sulfate anion via bipyrrole-strapped calix[4]pyrroles. Through these studies, we have discovered such cryptand-like receptors could extract the highly hydrophilic sulfate anion into an organic solvent from aqueous solutions when A336Cl was used as a coextractant. Chapter 3 depicts a novel meso-functionalized calix[4]pyrrole-based three dimensional networked molecular cage. Interestingly, upon treatment of fluoride, the resultant framework could be disassembled, which serves to release the inner molecules. Moreover, multiple lone pairs and hydrogen bonding donors provided by the calix[4]pyrrole building units allow for a highly selective adsorption for CO2 over other gaseous guest, such as N2, O2, H2 and CH4. Chapter 4 describes two novel calix[4]pyrrole-based uranyl complex cages, cage-1 and -2. The transformation from a tripodal cage (cage-1) to a tetrapodal system (cage-2) was achieved by a sunlight induced photochemical oxidation or via simple addition of hydrogen peroxide. Chapter 5 details the synthetic procedures and characterizations of all compounds used in these studies. Advisors/Committee Members: Sessler, Jonathan L. (advisor), Anslyn, Eric V.

▼ The purpose of this dissertation is to explore the applicability of Metal-Organic Frameworks (MOFs) to the adsorption of trace level of volatile organic compounds (VOCs) from the gas phase. The adsorption of VOCs on high surface area materials is an important process for many applications including purification and gas sampling (preconcentration). These applications often involve the complete removal of often toxic compounds that can be present at a wide range of concentrations (ppt-ppm). An effective adsorbent in applications such as gas sampling must often have the following properties: 1) complete capture of the targeted analytes without ???breakthrough???, 2) chemically inert to prevent changes in the composition of adsorbed analytes, 3) unaffected by the presence of humidity and other common gas stream components, 4) moderate interactions to allow for easy desorption and/or reactivation, and 5) sufficient chemical and thermal stability. All of the traditional microporous adsorbents which could be effectively applied to gas sampling applications (e.g. zeolites, silica gels, activated carbons, porous polymers) have limitations in one or more of the above criteria and there is an important need for novel adsorbents with improved performance. MOFs are an exciting class of crystalline nanomaterials which have been frequently explored for roughly the past decade. There is a large library of MOF materials which have been synthesized representing a wide variety of geometrical, chemical, and mechanical properties. In addition, the synthesis of MOFs allows for the capability of a priori designability of new structures possessing desired properties. MOFs are an ideal material for many adsorbent applications due to their well-defined geometries and chemistries combined with their extremely high surface areas. In addition, many MOFs show extreme thermal and chemical stability and most MOFs typically have lower heats of adsorption than other adsorbents. Despite their suitability to gas sampling applications, very little is known about the ability and mechanisms for VOC adsorption in MOFs. First, initial experiments were done investigating the applicability of zero-length column (ZLC) equilibrium and temperature-programmed desorption (TPD) applications to the characterization of VOC adsorption in MOFs. It was determined that significant complications are present in the applicability of both of these established techniques for VOC adsorption in MOFs. The analysis of TPD data in porous materials is an impossibly complex combination of competing mass transfer and equilibrium processes, and therefore it was determined that TPD was not a suitable technique for rapid screening of adsorption properties. The suitability of ZLC equilibrium studies is more promising to VOC adsorption in MOFs, however, the technique has some complications and presents no advantage over traditional chromatographic analysis. In the second part of this work, an inverse-gas chromatography (IGC) was employed to study the adsorption of a wide… Advisors/Committee Members: Masel, Richard I. (advisor), Masel, Richard I.

▼ This dissertation is centered on two areas: (i) rational design and synthesis of robust porous metal-organic frameworks using well-defined building blocks and (ii) synthesis of crystalline and amorphous coordination polymers based upon traditional organic chemistry. For the rational design and synthesis, we demonstrated how to achieve maximum interpenetration by fine tuning the size of the organic spacer using the Secondary Building Units (SBUs) approach, and how to avoid interpenetration using almost the same size of organic spacer via a pillared-layer strategy. For synthesis based on organic chemistry, we have developed a complementary and alternative covalent-based synthetic strategy for the synthesis of new coordination compounds in an effort to incorporate a wider range of compounds in the family of coordination materials. We synthesized a 4-fold mixed parallel/diagonal interpenetrating cubic metal-organic framework using octahedral zinc carboxylate Zn4O(OOC-)6 SBUs as nodes and a long and narrow organic ligand, 1,4-(4-carboxylic-phenyl) butadiyne, as linkers. Despite the maximum 4-fold interpenetration, it contains large void space and high specific surface area. We synthesized two pillared-layer metal-organic frameworks using infinite 2D tetragonal grid lattices and kagomé lattices as Supramolecular Building Blocks (SBBs), respectively. The interpenetration was forbidden in these two frameworks by judicious choice of impenetrable 2D SBBs. Both pillared-layered frameworks possess unprecedented levels of porosity. The pillared-layer architecture paradigm we demonstrated in this dissertation points to a design strategy for the synthesis of large microporous, even mesoporous metal organic frameworks (MOFs). We modified discrete SBUs, synthesized coordination polymer gels and crystalline coordination polymers by using common organic coupling reactions including Huisgen 1, 3-dipolar cycloaddition and homo-alkyne coupling reactions. We modified coordination nanospheres with long hydrocarbon chains by esterification reactions. The new covalent- based synthetic method can provide a wider range of coordination materials.

La détection de faibles quantités de petites molécules volatiles, qu’elles soient polluantes, utilisées comme armes chimiques ou encore explosives présente un intérêt sociétal certain. Les polymères de coordination poreux (PCPs) ou ’Metal-Organic Frameworks‘ (MOFs) sont des solides poreux qui peuvent être décrits par l’association de ligands organiques et de briques inorganiques interagissant par liaisons fortes et définissant une structure cristalline avec des pores de différentes tailles et formes. La large gamme d'application de ces solides (séparation, stockage, biomédecine...) repose sur leurs diversités chimique et structurale. Par exemple, il est possible de synthétiser des MOFs luminescents en utilisant un ligand organique lui-même luminescent. Le coeur tétrazine et ses dérivés sont des bons candidats pour cet objectif, puisqu'ils présentent des propriétés de fluorescence remarquables : émission dans le visible (λem~560 nm), bon rendement quantique. De plus, cette fluorescence peut être modifiée par la présence de molécules riches en électrons, ce qui laisse envisager son utilisation comme capteur moléculaire. Nos travaux se sont de plus focalisés sur des métaux à haut degré d'oxydation (Al(III), Zr(IV)) susceptibles de conférer aux solides une stabilité en milieu aqueux adéquate pour les applications envisagées. Deux acides carboxyliques à base de tétrazine, adaptés à la préparation de MOFs, ont tout d'abord été synthétisés. Le premier a été utilisé pour préparer un MOF à base de zirconium.La structure du solide, et entre autres son caractère flexible, ainsi que ses propriétés optiques ont été étudiées. Particulièrement, ses performances en tant que capteur d'amines aromatiques et de phénol ont été évaluées. La réactivité du second ligand avec les ions lanthanides a aussi été explorée et plusieurs solides ont été isolés, leur structure, caractérisée. Leurs propriétés optiques ont été évaluées, afin d'établir des relations entre la structure du MOF et la fluorescence de la tétrazine. Ensuite, avec ce même ligand, une stratégie de synthèse à ligand mixte a été adoptée pour incorporer la tétrazine dans des MOFs. Il s'agit de partir d'une structure aux propriétés avantageuses (stabilité, porosité) et de substituer une partie de ses ligands organiques ‘inactifs’ par des tétrazines. Ceci peut s'effectuer pendant la synthèse ou via un traitement post-synthétique. Les propriétés optiques des solides obtenus ont été enfin étudiées et leur efficacité en tant que capteur évaluées.

Detection of low concentrations of small organic molecules, which can be hazardous, polluting or used as chemical weapons, represents a societal problem worth addressing. Metal-Organic Frameworks (MOFs) are a class of porous crystalline materials that can be described as an association of inorganic subunits and organic ligands defining an ordered structure with accessible cavities of various size and shape. The wide range of potential applications for these materials (biomedicine, gas separation, catalysis...) relies on their chemical and…

▼ This thesis describes the synthesis, characterisation and catalytic testing of multifunctional immobilised metal nanoparticle in metal-organic framework (MOF) materials. Combining the activity of metal nanoparticles with the porosity and Lewis acidity of metal-organic frameworks provides a single catalytic material which can perform multi-step reactions. Strategies to immobilise the metal nanoparticles within the metal-organic frameworks have been investigated. Immobilisation has been achieved by applying three different methodologies. First, deposition of metal nanoparticle precursors within mesoporous MOFs is discussed. Chapter 3 shows the effectivity of the double solvents deposition technique to achieve dispersed and small nanoparticles of around 2.7 nm. The best system combined Pd nanoparticles with MIL-101(Cr). This system was further investigated in tandem reductive amination catalysis, discussed in Chapter 4, to investigate the activity and selectivity provided by these multifunctional catalysts. Another immobilisation technique was performed by coating Pd decorated SiO₂ spheres with a MOF layer. Using this technique, MOF was grown cyclically in solution, providing tuneable shell thicknesses of MOF on the metal nanoparticle decorated oxide spheres. While the homogeneity of the MOF shell needs more optimisation, it was determined that the surface charge on the spheres played an important role in the growth of MOF in the desired location. Finally, the third immobilisation technique is the core-shell growth of MOF on colloidal metal nanoparticles. Polymer-capped metal nanoparticles with well-defined shapes were synthesised and characterised. From here, the optimisation of conditions for core-shell growth of UiO-66 and MIL-100(Sc) were investigated. Conditions which provided the desired core-shell morphology were found for both MOF types. These materials were then subsequently used in tandem reductive amination catalysis and a more straightforward styrene hydrogenation. It was shown that the metal nanoparticles remain active catalysts within either MOF shell and the MOF shell stabilises the metal nanoparticle and acts as a Lewis acid catalyst.

▼ Esta tesis doctoral resume nuestros esfuerzos por contribuir al desarrollo de nuevos catalizadores heterogéneos basados en compuestos Metal-Orgánico estructurados (MOFs). Para ello, y con el fin de cubrir un amplio espectro de posibilidades en el diseño de catalizadores basados en MOFs, se han considerado distintos materiales en los que los centros catalíticos se encuentran situados en los nodos metálicos, en los ligandos orgánicos o encapsulados en el interior del sistema poroso del material. En consecuencia, los resultados presentados se organizan en tres bloques, en función de dónde se localizan los centros activos dentro del material. A lo largo de este estudio se ha prestado especial interés en evaluar el verdadero potencial de los MOFs con respecto a otros catalizadores homogéneos y heterogéneos existentes, así como en determinar su estabilidad y reusabilidad, ya que se trata de las dos objeciones más importantes que se plantean al considerar el uso de los MOFs para aplicaciones catalíticas. En el primer bloque de resultados se ha evaluado la actividad catalítica de varios MOF con iones Cu2+ en los nodos metálicos en reacciones que pueden ser catalizadas por otros catalizadores homogéneos y heterogéneos que contienen este mismo tipo de centros. En particular, varios MOFs de cobre han demostrado ser catalizadores heterogéneos activos, selectivos, estables y reusables para la oxidación aeróbica de alquenos activados (Capítulo 1), acoplamiento oxidativo C-O por activación directa de enlaces C-H (Capítulo 2), síntesis regio-selectiva de triazoles por adición “click” de azidas a alquinos (Capítulo 3), así como para la síntesis de propargilaminas y derivados heterocíclicos mediante reacciones de acomplamiento de multicomponentes. (Capítulo 4). Para completar este bloque de resultados, en el capítulo 5 se evalúa el comportamiento de MOFs con oxo-agregados de Zr con propiedades semiconductoras como fotocatalizadores para la generación de H2 por disociación de agua . En el capítulo 6 se describe el desarrollo de un nuevo método de modificación post-síntesis que permite convertir los grupos amino libres en los ligandos de un MOF en especies quelante tipo oxamato, lo que nos permite introducir centros catalíticos metálicos adicionales directamente anclados a las paredes del MOF. El potencial de esta estrategia se demuestra a través de la introducción de iones Cu2+ y el estudio de la actividad catalítica de los materiales resultantes en reacciones típicas catalizadas por los nuevos centros, como las ya descritas en los Capítulos 3 y 4. Como último bloque de esta tesis, en el Capítulo 7 se describe la preparación de nanopartículas de Pd encapsuladas en el interior de MOFs de Zr (UiO-66 y UiO-67) mediante adsorción en fase gas de un precursor de Pd seguida de descomposición/reducción mediante irradiación con luz UV. La localización de las nanopartículas metálicas exclusivamente en el interior de las cavidades estructurales confiere al material propiedades de selectividad de forma, como demostramos para la reducción… Advisors/Committee Members: Corma Canós, Avelino (advisor), Llabrés i Xamena, Francesc Xavier (advisor).
