▼ Abstract Ionic liquids (ILs) are organic salts with melting points at or below 373 K. As the physicochemical properties of ionic liquids can be modulated according to need, they are also called “designer” solvents. A comparative study of the intermolecular dynamics of a nonpolar molecular solute CS2 in a series of monocationic ILs, 1-alkyl-3-methylimidazolium bis(trifluoromethane-sulfonyl)amide ([CnC1im][NTf2] for n = 3-5) and their dicationic equivalents, 1,6-bis(3-methylimidazolium-1-yl) alkane bis(trifluoromethane-sulfonyl)amide ([(C1im)2Cn][NTf2]2 for n = 6, 8 and 10) was done as a function of concentration using optical heterodyne-detected Raman-induced Kerr effect spectroscopy (OHD-RIKES). The OHD-RIKES data indicate that CS2 molecules experience a stiffer potential in dicationic ILs as compared to monocationic ILs. The effect of cation symmetry on the solvation of solute molecules in imidazolium-based ILs was investigated by comparing the OKE spectra of CS2 in asymmetric ILs, ([CnC1im][NTf2] for n = 3, 5 and 7) to those of CS2 in same number of alkyl chain carbon atoms, symmetric ILs ([(Cn)2im][NTf2] for n = 2-4) using OHD-RIKES. The OKE results indicate that the CS2 molecules experience stiffer potential in shorter chained symmetric IL C2C2, than in asymmetric IL, C3C1. But in longer alkyl chain length, CS2 molecules experience similar stiffness of potential irrespective of symmetry of the alkyl chains. Two series of aromatically functionalized ILs containing common cations 1,3-dibenylimidazolium and 1-(2-naphthylmethyl)-3-methylimidazolium, but with varying anions were successfully synthesized and crystallized. Determinations of single X-ray crystal structures indicate that variation of anions has an effect on hydrogen bonding and π-stacking interactions in the crystalline states of these ILs. In addition, these two series of ILs that differ in symmetry due to the position of the phenyl rings had different patterns of packing of ions in the crystal lattice. Understanding how cation structure determines physicochemical properties of ILs helps in further tuning and designing ILs for a specific application. The densities of the homologous series of branched ILs and their linear counterparts with a given number of alkyl carbon atoms N, were measured as functions of temperature. This study showed that branching of alkyl chains does not affect the densities of ILs.

▼ In the past decades, ionic electroactive polymers (i-EAPs) have become attractive transduction materials due to their relatively large electromechanical actuations that can be generated under low voltages (~ a few volts) and many other advantages, such as flexibility and light weight. These i-EAP actuators hold promises for applications including artificial muscles, robots, micro-electromechanical systems (MEMS), nano-electromechanical systems (NEMS), and energy harvesting. On the other hand, one critical issue in utilizing i-EAPs for those applications is how to significantly improve the electromechanical performance, including the actuation speed, actuation strain level and efficiency. Particularly, extremely low efficiency is the major drawback of current i-EAP actuators. This dissertation discusses the physics in ionic polymer composite actuators and develops solutions to improve the actuation strain, speed, and efficiency. One general approach through the entire dissertation is to electrically and electromechanically analyze ionic polymer composite actuators to identify the limiting factors, and design a strategy to guide material selection or device fabrication for better performance. Two types of ionic polymer actuators will be discussed: (i) ionic polymer conductive network composite (IPCNC) actuators that consist of an ionic liquid (IL) containing polymer membrane and large surface area composite electrodes, referred to as the “IPCNC actuator”; and (ii) IL containing ionic polymer membranes with planar Au electrodes, referred to as the “ionic polymer membrane actuator”. While the composite electrodes in the IPCNCs provide large specific capacitance for ion storage which enhances the bending actuation, the ionic polymer membrane actuators offer a simple structure for device modeling and material analysis. IPCNC actuators are fabricated and discussed first. IPCNCs with disordered CNC nanomorphology (nanoscale morphology), mostly made with conducting nanoparticles, are discussed in Chapter 3, while IPCNCs with ordered CNC nanomorphology, in which vertically aligned carbon nanotubes (VA-CNTs) are implemented, are discussed in Chapter 4. In these chapters, electrical and electromechanical models are established to analyze the performance of IPCNC actuators. Firstly, electronic equivalent circuits are developed to model the complex frequency-dependent impedance and explain the initial response (t<10s) of ionic polymer composite actuators. It is found that the low frequency responses of these actuators indicate Warburg diffusion (semi-finite diffusion). When there is no CNC or when CNC is very thin (tens of nm), a simple equivalent circuit, which only consists of Warburg impedance AW, bulk resistance R, and electric double layer capacitance Cdl can be used, where Cdl and AW dominate the fast and slow responses of the actuator, respectively. When the CNC is thick (several µm), the aforementioned equivalent circuit is no longer adequate; therefore, the de Levi transmission line is introduced to model the CNC layer,…

Room Temperature Ionic Liquids (RTILs) are a new class of solvents receiving increasing attention for their possible use as alternative solvent/electrolyte to conventional electrolytes in electrochemical setups. Due to their wide electrochemical window, appreciable conductivity, ability to dissolve wide range of organic and inorganic substrates, low vapour pressure, high chemical and thermal stability and above all ability to stabilize transient species, RTILs are considered as excellent media for ecofriendly, innovative and sustainable electrochemistry. Besides all the advantageous features RTILs do have, their wide spread use for electrochemical investigations and applications is yet to be realized. Some practical concerns associated with use of RTILs in electrochemical setups and a lack of complete understanding about their role as solvent/electrolytes in electron transfer and the associated reactions are the main reasons that currently hamper their use for electrochemical investigations and applications. In this regard some fundamental aspects related to RTILs, like equilibrium and transport properties of pure RTILs and alteration of these properties through use of cosolvents or variations in experimental parameters, specialities of electrode/RTIL interfaces over that of the electrode/conventional electrolyte solution interfaces, impact of RTIL specific effects on heterogeneous electron transfer and associated chemical reactions need some detailed investigations. Work presented in this thesis is an attempt to have a better understanding about some of these challenges one comes across, while working with RTIL based electrochemical setups. Electrochemistry of model redox systems was explored to test the validity of established theories in RTILs and to realize the potential advantages of RTILs over conventional solvents. Solvent dynamic control over transport, charge transfer processes and ion pair effects are discussed. The advantageous aspects due to solvent specific effects of RTILs over thermodynamic, kinetic and mechanistic aspects of heterogeneous electron transfer and associated reactions are also discussed.

As part of an ongoing program in the area of green chemistry, we have considered the synthesis of room temperature ionic liquids and their application as reaction medium in organic transformations. The efforts and contribution towards the preparation and application of ionic liquids have been summarized in the form of this thesis. The thesis entitled ?Synthesis of ionic liquids: Application to Wittig, reduction and aromatic nucleophilic substitution reactions? is divided into five chapters. CHAPTER-I: Introduction to ionic liquids This chapter deals with the 12 principles of green chemistry, ?E? factor, atom efficiency, possible alternative solvents and their applications, ionic liquids, and a few examples on the application of RTILs in organic synthesis. CHAPTER-II: Synthesis and characterization of citronellal based chiral ionic liquids Chapter 2 deals with the preparation and characterization of a series of chiral ionic liquids starting from the chiral pool citronellal. Several new chiral ionic liquids were prepared starting from both the isomers of citronellal with dialkyl amine as the amine source. The Schiff base, thus obtained, was reduced and further reacted with alkyl halides to give ionic liquids. The strategy could begeneralized with several dialkyl amines to design chiral ionic liquids.

Most of the ionic liquids prepared in this series were found to be liquids at room temperature. CHAPTER-III: Application of ionic liquids in the Wittig reaction and synthesis of lacidipine using ionic liquids Chapter 3 deals with the application of ionic liquids in the Wittig reaction.

Research Doctorate - Doctor of Philosophy (PhD)

Molecularly Imprinted Polymers (MIPs) are selective recognitions elements that have biological, chromatographic and sensory applications. While methods exist to reproducibly form MIPs with high affinity for a wide range of target molecules, improvements in production efficiency and selectivity are constantly being sought. Room Temperature Ionic Liquids (RTILs) represent a reasonably novel class of ‘green solvents’ which have been widely utilised for polymerisation reactions, resulting in enhanced polymerisation rates and polymer yields. In this study, the performance of imprinted polymers prepared in RTILs compared against equivalent formulations prepared using conventional organic solvents (Volatile Organic Compounds, or VOCs) is reported. RTILs were found to greatly improve reaction efficiency compared to VOCs whilst maintaining reasonable levels of selectivity. The effect of variables such as RTIL structure, polymerisation temperature and solvent volume on the efficiency and structure of a cocaine-imprinted MIP were investigated and were found to affect polymer properties such as surface morphology, swelling, zeta potential, degree of crosslinking as well as selectivity for the template. Imprinting factors as high as 2.2 were observed for RTIL-prepared MIPs under initial rebinding conditions when using [bmim]BF₄ as polymerisation solvent, compared with the highest imprinting factor of 1.6 for the polymers prepared in CHCl₃. Optimisation of rebinding conditions resulted in ~26% improvement in selectivity for both RTIL and VOC-prepared polymers when using DCM as rebinding solvent. Molecular modelling and NMR analysis of R, S-propranolol-imprinted polymers indicated some interaction between the RTIL anion and the template and monomer, although this was not found to prevent template/monomer associations in the RTIL [bmim]PF₆. [bmim]PF-₆prepared polymers showed good selectivity (imprinting factor of 2.3) and affinity for the template over other compounds, although binding capacity was lower than for the VOC-prepared polymers. The binding capacity for the RTIL-prepared polymers was enhanced through the use of RTILs of increased alkyl chain lengths as polymerisation solvent and by optimisation of rebinding conditions, with the highest imprinting factor of 3.8 observed when rebindings were conducted in methanol.

▼ Wind power is one of the fastest growing power sources worldwide. Large installations of wind power generation are prominent in Asia, Europe and the United States. The gear boxes and bearings of large wind turbines continue to be huge liabilities and fail well short of their 20 year design life. These mechanical failures impose long and expensive repairs. The reliability of wind turbine drive systems may be improved through advances in lubrication. Furthermore, increasing environmental regulations and public policy have ushered in the need for development and implementation of environmentally friendly lubricants. Over the past decade, ionic liquids have emerged as high performance fluids and lubricant additives due to their unique characteristics. Ionic liquids have the ability to form stable ordered layers in liquid state and have been shown to have the potential to be used as high-performance lubricants; however, most of the ionic liquids currently used in lubrication are composed of halogen-containing anions. It is well known that these anions will decompose in presence of water, liberating highly toxic and corrosive species. There is an urgent need to design halogen-free and hydrolytically stable ionic liquids to avoid this negative effect. In this study, the tribological behavior of two phosphonium-based ionic liquids, is investigated as additives of a commercially available bio-oil in steel-steel contact. One of the ionic liquids is halogen-free and will be compared to an ionic liquid that contains halogens. Bio-oil and ionic liquid mixtures containing 0.5 ,1 and 2.5 wt.% of both ionic liquids are studied using a pin on disk tribometer and compared to a commercially available, fully formulated lubricant over a range of three speeds. Results showed, that under the fastest speed tested, At the optimal concentration of 1% [THTDP][NTf2], a wear reduction of 74% was achieved with respect to the base Biotelex. A 66% reduction was observed with respect to the Mobilgear. Similarly, the optimal concentration of 2.5% [THTDP][Phos] displayed a 68% wear reduction compared to the base Biotelex and a 58% reduction compared to the Mobilgear.

▼ The purpose of this research is to investigate the physical properties of ionic liquids (ILs) confined inside nanopores of different materials and morphologies. We are interested to study the effect of pore material, morphology and addition of organic solvents on the properties of confined ILs. Understanding the behavior of ILs inside nanopores is relevant to potential applications of these systems in electrochemical double layer capacitors (EDLCs) and dye sensitized solar cells (DSSCs). Such a fundamental understanding is also crucial to optimize the synthesis of hard-templated 1D nanostructures (nanorods, nanotubes, nanowires) based on organic salts, which may be imparted properties (e.g., magnetic, optical) that are desirable for different applications (magnetic hyperthermia cancer treatment, medical imaging, sensors). In this work we have used molecular dynamics (MD) simulations to investigate systems of representative ILs, [BMIM+][PF6-] and [EMIM+][TFMSI-], inside several model materials (e.g., slit-shaped graphitic and titania pores, carbon nanotubes). Formation of different layers of ions was observed for the confined ILs irrespective of variations in pore size, shape, material and amount of solvent. In all cases, change in pore loading leads to lower densities of ions in the center of the pore. The cations close to the pore walls tend to align with their imidazolium rings parallel to the pore surface in the case of carbon materials, and multiple preferential orientations are observed in the case of titania pores. For all porous materials studied, the dynamics of the ions depend strongly on their location with respect to the surface; bulk-like dynamics are generally observed for the ions in the center regions of the pore, with the dynamics becoming slower as the ions get closer to the pore surfaces. Addition of acetonitrile solvent also shows similar layering behavior for ILs and solvent near the pore wall with less variation in the center of the pore. Preferential orientations of the ions remain unaffected and solvent molecules tend to align flat near the pore surface. The dynamics of the ions and molecules increases linearly with increase in IL molar concentration both near the wall and in the center of the pore.

▼ Gas sensors have been applied for a wide variety of applications in environmental and occupational health and safety (OHS) sectors. Current commercial amperometric gas sensors often suffer from short lifetime due to evaporation of electrolyte (e.g. H2SO4/H2O mixtures or organic solvents such as acetonitrile or propylene carbonate). Non-volatile ionic liquids (ILs) are promising electrolytes which provide a pathway to solve the evaporation problem in amperometric gas sensor. However the IL-based amperometric gas sensor suffers from low sensitivity and slow response time as a result of intrinsic high viscosity of IL. This thesis focuses on the development of IL-based amperometric gas sensor using microelectrode arrays prepared by microcontact printing (μCP) of a passive layer of self-assembled monolayer (SAM) onto gold electrodes to obtain enhanced mass transport in ILs. Thus the thesis is consisted of following content:i) The stability of SAMs such as 1-hexadecanethiol (HDT) and 11-mercaptoundercanoic acid (MUA) at gold and platinum electrodes are established in protic and aprotic room temperature ionic liquids (RTILs). SAMs in ILs show wider potential window compared to that in aqueous solution. Interestingly, it is found that the SAMs prepared by using ionic liquid as solvent are electrochemically more stable than that prepared from organic solvents.ii) An oxygen sensor system has been designed and established using microelectrode array fabricated by μCP of HDT on gold electrodes. The micropatterned gold electrode is immersed into a thin layer of hydrophobic IL electrolyte (e.g. 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [BMIM][NTf2]). The results demonstrate that the microelectrode array sensor has better sensitivity and higher current density compared to macroelectrode-based gas sensor.iii) Finally, a high performance IL microarray gas sensor is developed using individual IL microdroplets as sensing units for oxygen sensing. Benefiting from non-volatility of ILs, small volume of droplet size (short diffusion distance), large surface-to-volume ratio, the new sensor design demonstrates significantly enhanced sensitivity and response time, compared to a conventional macroelectrode based gas sensor.

▼ Tantalum is a tough, ductile, refractory metal that is highly corrosion resistant. The corrosion resistance of tantalum is evident in diverse conditions, including high temperature and severe chemical environments. Application of a tantalum layer onto other metal substrates would be a beneficial corrosion-resistance technique. The method investigated for application of tantalum onto various metal substrates was via electrodeposition from ionic liquid electrolytes. The use of ionic liquids allows the electrodeposition process to be performed at lower temperatures (less than 200 degrees Celsius) than the mainstream process of deposition at higher temperatures (750-800 degrees Celsius) from molten salt electrolytes. The lower operating temperature ultimately protects the substrate from increased rates of corrosion as well as strength loss through annealing. Recently published literature on the electrodeposition of tantalum onto other substrates formed the basis for this research. This investigation attempted to determine whether previous research could be expanded upon through the variation of type of ionic liquid, the addition of organic solvents or alkali metal salts, and destabilization of tantalum-halide clusters. An electrochemical cell was constructed that utilizes a tantalum foil anode and a steel or nickel cathode. The electrolyte contained tantalum salts dissolved in various ionic liquids, with or without various organic solvents. The cell was protected from water vapor and oxygen by being placed into a glove box containing an ultra-high purity nitrogen atmosphere. The actual plating process was conducted galvanostatically, and the applied current and electrolyte composition were varied to determine the effect on the deposition process. Electrodeposits formed during experimental trials were analyzed through the use of scanning electron microscopy (SEM) with energy-dispersive x-ray spectroscopy (EDS). This study represents particular advancements in the body of knowledge on electrodeposition of tantalum from ionic liquids. Individual ionic liquids were evaluated that had not been previously investigated as refractory metal electrolytes. Additionally, the thickest known tantalum electrodeposits, and electrodeposits with the highest reported concentrations of tantalum were produced in this study.

▼ Continuous monitoring and real-time detection of gas molecules in the environment is very important in every aspect of modern society. There is an increasing demand to develop robust amperometric gas sensors with extended lifetimes and enhanced overall performance (sensitivity, selectivity, response time and limit of detection. Current commercial amperometric gas sensors often suffer from short lifetime due to evaporation of conventional electrolyte (e.g. aqueous or organic solvents). Even though membranes were introduced in gas sensor design to reduce the evaporation rate of the electrolyte, but it is unable to solve the problem completely.In this thesis, we described strategies to fabricate robust and “membrane-less” electrochemical gas sensors with improved overall performance, using ionic liquids (ILs) as substitute electrolytes. First, microcontact printing was utilised to fabricate IL-based microchannels electrode gas sensors. The fabricated sensor was firstly applied for carbon dioxide sensing and compared with ionic liquid-based macroelectrode gas sensor. The enhanced performance of the IL-based microchannels electrode gas sensors was observed by using long-term chronoamperometry technique for carbon dioxide sensing. The IL-based microchannels electrode gas sensor is then further studied for toxic gases detection including ammonia and hydrogen chloride. On the timescale of the electrochemical experiments, no unusual behaviour or detrimental effects were observed on the Au modified microchannels electrode. Two different electrochemical techniques, linear sweep voltammetry (LSV) and chronoamperometry been utilised for toxic gas sensing with two different IL. Very low LODs were obtained from 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C2mim][NTf2]) by LSV (4.1 ppm for ammonia and 3.6 ppm for hydrogen chloride). The [C2mim][NTf2]-based microchannels electrode sensors not only demonstrate a fast response (t90: 15-30 s) but also excellent linearity in real-time sensing with a sensitivity of 1.8 nA ppm−1 (for ammonia) and 25.5 nA ppm−1 (for hydrogen chloride), respectively. Furthermore, the IL-based microchannels electrode gas sensor was electrodeposited with platinum nanoparticles (PtNPs) and demonstrated for hydrogen gas sensing for the first time. A linear trend line and a ultrafast response (less than 2 s) were achieved in [C2mim][NTf2] using the proposed sensor design to measure hydrogen gas in the range from 10-100% and 1-10% with a sensitivity of 1.2 × 10−7 A %−1 and 2.1 × 10−7A %−1, respectively. Moreover, the IL-based microchannels electrode was also electrodeposited with copper nanoparticles (CuNPs) and presented for carbon dioxide sensing. Benefiting from non-volatility of ILs, a small volume of droplet size (short diffusion distance), large surface-to-volume ratio, more electroactive sites on Cu nanoparticles, this IL-based CuNPs-microchannels gas sensor demonstrates improved sensitivity and response time (about 10-20 s faster) for CO2 sensing, compared to IL-based microchannels gas… Advisors/Committee Members: Zhao, Chuan, Chemistry, Faculty of Science, UNSW.

▼ Molecular dynamics (MD) simulations of various room temperature ionic liquids (RTILs), RTIL/lithium salt mixtures, and RTIL/lithium salt/organic solvents mixtures have been conducted using a well-established polarizable force field which demonstrated unprecedented accuracy and transferability in simulations of liquids, electrolytes, and polymers. The influence of inclusion atom polarizability on the accuracy of properties predicted from MD simulations of RTILs has been systematically investigated. Simulations of RTILs in which the atom-based polarizability was set to zero for all atoms (nonpolarizable model) resulted in changes in thermodynamic and dynamic properties from those predicted by the polarizable force field (polarizable model). Investigation of structural and dynamical correlations using both the polarizalbe and nonpolarizable model allowed us to obtain a mechanistic understanding of the influence of polarization on dynamics in the RTILs investigated. MD simulations of N-methyl-N-propylpyrrolidinium(pyr13) bis(trifluoromethanesulfonyl)imide(Ntf2) ionic liquid [pyr13][Ntf2] mixed with [Li][Ntf2] salt have been conducted at 363 K and 423 K. Mixture simulations with lithium salt mole fractions between 0% and 33% at 363 K and 423 K yield densities, ion self-diffusion coefficients, and ionic conductivities in very good agreement with available experimental data. The concentration dependence of Li+ solvation structure, conductivity, and diffusion mechanism has been successfully investigated. The organic solvents acetonitrile (ACN) and ethylene carbonate (EC) wereivadded into the [pyr13][Ntf2]/[Li][Ntf2] mixtures at two concentrations (20 mol% and 40 mol%). Ion mobility was found to be improved in the diluted electrolytes. In addition, EC and ACN molecules were found to be able to influence the coordination structure and diffusion mechanism of Li+ cations. The interfacial structures of the mixtures near charged and uncharged graphite electrode have been exposed as well, using an electroactive interface molecular dynamics simulation methodology. Multilayer structures were observed near the atomically flat graphite electrodes. The orientations of the components in the mixtures near the charged and uncharged surface were discussed thoroughly.

Οι ζεόλιθοι είναι μικροπορώδεις αργιλοπυριτικές κρυσταλλικές ενώσεις οι οποίες αποτελούνται απο τετράεδρα SiO4 και AlO4 που σχηματίζουν κρυσταλλικά πλέγματα σε μία, δύο ή τρείς διαστάσεις. Εξαιτίας των μοναδικών φυσικοχημικών ιδιοτήτων τους, οι ζεόλιθοι σήμερα χρησιμοποιούνται σε ένα μεγάλο πλήθος εφαρμογών τόσο σε βιομηχανικό όσο και σε εργαστηριακό επίπεδο. Από την άλλη μεριά, ώς ιονικά υγρά ορίζονται οι ιοντικές ενώσεις (άλατα) εκείνες οι οποίες στη θερμοκρασία δωματίου βρίσκονται στην υγρή φάση. Η αμελητέα τάση ατμών, το χαμηλό σημείο τήξεως και οι εξαιρετικές ηλεκτρικές ιδιότητες τους έχουν οδηγήσει στην ολοένα και πιο ευρεία εφαρμογή τους. Ο σκοπός της παρούσας διατριβής είναι η μελέτη του εγκλωβισμού Ιονικών Υγρών σε ζεόλιθο και ο χαρακτηρισμός των παραγόμενων σύνθετων υλικών. Στο πρώτο μέρος της παρούσα διατριβής συνετέθησαν δύο διαφορετικοί ζεόλιθοι και πιο συγκεκριμένα NaY-FAU και BEA με τρείς διαφορετικές αναλογίες Si/Al (250, 50 και 25). Οι παραγόμενοι ζεόλιθοι χαρακτηρίστηκαν με Φασματοσκοπία Περίθλασης Ακτίνων-Χ (XRD), Ηλεκτρονική Μικροσκοπία Σάρωσης (SEM) και φυσιορόφηση Ν2. Στο δεύτερο μέρος της παρούσας διατριβής έγινε μελέτη του εγκλωβισμού ΙΥ σε ζεόλιθο. Πιο συγκεκριμένα μελετήθηκε ο εγκλωβισμός του 1-Η-3-μεθυλιμιδαζολο τριφθορομεθανοσουλφόνυλο ιμιδίου στο ζεόλιθο NaY-FAU. Tα προκύπτοντα σύνθετα υλικά ΙΥ/Ζ τόσο ως προς τις φυσικοχημικές αλλά και ως προς τις ηλεκτροχημικές τους ιδιότητες. Πιο συγκεκριμένα, μελετήθηκαν 2 διαφορετικές μέθοδοι εγκλωβισμού του ΙΥ στο ζεόλιθο NaY-FAU: απευθείας προσθήκη του ΙΥ στον απαερωμένο ζεόλιθο (Μέθοδος 1) και με διάλυση αρχικά του ΙΥ σε MeOH και προσθήκη του ζεόλιθου στο διάλυμα (Μέθοδος 2) και μελετήθηκε η επίδραση της αρχική αναλογία ΙΥ/Ζ και της επίδρασης της διάρκειας της εκχύλισης Soxhlet στη ποσότητα του ΙΥ που παραμένει εγκλωβισμένο και στη δομή του τελικού προϊόντος. Τέλος τα προκύπτοντα συστήματα ΙΥ/Ζ χαρακτηρίστηκαν ως προς την ιοντική τους αγωγιμότητα με Φασματοσκοπίa Σύνθετης Αντίστασης (Α. C. Impedance Spectroscopy).

Zeolites are microporous crystalline compounds that are cosntituted by SiO4 and AlO4 tetrahedra thus forming crystalline structures in one, two or three dimensions. Due to their unique physicochemical properties zeolites are widely used in industrial and laboratory applications. On the other hand, Ionic Liquids are liquids that are liquids at room temperature. Their negligible vapour pressure, the low melting point and their unique electrochemical properties have caused their extensive use in different applications. The scope of this thesis is to study the encapsulation of Ionic Liquids into zeolite structure and the characterization of the obtained composite materials. The first part presents the synthesis and characterization of two different zeolites: NaY-FAU and BEA with three different Si/Al ratio (250, 50 and 25). The obtained zeolites were characterized using X-Ray Diffraction Spectroscopy, Scanning Electron Microscopy, N2 physisorption and Thermogravimetric Analysis.

Os resultados obtidos com líquidos iônicos foram comparados com os obtidos por método convencional já desenvolvido em nosso laboratório, e demonstraram grande melhora nos tempos reacionais e manutenção dos bons rendimentos. Os líquidos iônicos também foram utilizados em reações de enoléteres com acilantes menos reativos como cloreto de acetila e cloreto de benzoíla, provando ser bons meios catalíticos neste tipo de reação. Os líquidos iônicos foram utilizados como meio para a síntese de trifluoro[cloro]metil β-enaminonas a partir de 1,1,1-tricloro(fluor)-3-alquen-2-onas. Também foi avaliada a reutilização dos líquidos iônicos (recarga) após as reações mencionadas. Em todos os casos, após a recarga os tempos reacionais foram mantidos sem perda significativa nos rendimentos.

The results obtained in the presence of ionic liquids were compared with those obtained in the conventional condition already developed in our laboratory, and they demonstrated great improvement in the reaction times, with maintenance of the good yields. Ionic liquids also were used in the reactions of enolethers with poor reactive acylants, as acetyl chloride and benzoyl chloride, proving its efficiency as catalytic media in this reaction type. The ionic liquids were still used as medium in the synthesis of β-enaminones bearing a trifluoro[chloro]methyl starting from the 1,1,1-trichloro(fluoro)-3-alken-2-ones. It was also evaluated the reutilization of the ionic liquids (recharge) after the reactions mentioned above. In all of the cases of recharge there was the maintenance of the times reacionais without significant loss of yield.

▼ This study focuses on the effects of surface heterogeneities on the behaviour of ionic liquids. Ionic liquids have shown great promise as both electrolyte replacements and as lubricants in industrial applications. Previous studies have focused on ionic liquid behaviour on flat substrates. Understanding the behavior of ionic liquids (ILs) either confined between rough surfaces or in rough nanoscale pores is of great relevance to extend studies performed on ideally flat surfaces to real applications. This work is comprised of three sets of experiments to determine the effects of nanoscale roughness and chemical surface properties on IL static and dynamic behavior. The first is an extensive investigation of the structural forces between two surfaces with well-defined roughness (<9 nm RMS) in 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([HMIM] Ntf2) by atomic force microscopy. Statistical studies of the measured layer thicknesses, layering force, and layering frequency reveal the ordered structure of the rough IL-solid interface. The second was a study of the frictional forces in [HMIM] Ntf2 on surfaces of varying roughnesses, both with and without confinement. These experiments focused on speed and load dependence of the friction force. The third investigated the effect of plasma treatment vs. UV ozone treatment of silica surfaces, in both [HMIM] Ntf2 and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM] Ntf2), on friction forces and adhesion. These experiments were completed without confinement. This work shows that the equilibrium structure of the interfacial IL strongly depends on the topography of the contact. Most broadly an increase in layering is seen with confinement, as expected, but the layer size and push out forces are largely dependent on surface roughness. It is observed that the flat substrate shows a distinct layering pattern from the rough substrates; however notably layering is present on even the roughest surfaces. This work also showed that the decrease in ordering due to the presence of roughness leads to a decrease in friction forces, both unconfined and confined. The presence of roughness also appears to decrease the speed dependence of the friction response. This decrease in friction is likely due to an increase in liquid-like behavior of the IL on the rough surface. Last this work showed an increase in adhesion and friction force due to plasma treatment for [EMIM] Ntf2 with time but not for [HMIM] Ntf2. This reveals that while both ILs are hydrophobic they have different time-dependent responses to the more hydrophilic surface rich in silanol groups. Overall this work illuminates the importance of studying systems closer to real applications as it clear that roughness and surface chemical modifications play an important role in IL surface behavior. It also suggests that IL may become more liquid-like than previously thought in rough pores, or between rough surfaces increasing their viability as both electrolyte replacements and lubricants.

Research Doctorate - Doctor of Philosophy (PhD)

Ionic Liquids (ILs) are a subset of molten salts distinguished by melting points below 373 K. ILs are unusual among solvents in that they are composed entirely of ions, with no neutral species present. Over the last decade or so, ILs have emerged as an attractive class of solvents for a range of chemical applications, mostly due to their ‘green’ characteristics and remarkable liquid properties. Understanding the ion arrangements in ILs is important as many of these applications and properties are related to their (bulk or interfacial) solvent structure. Historically, ILs were considered structurally homogeneous solutions of freely dissociated ions or ion pairs. Whilst these concepts are adequate for molten salt melts, IL ions can participate in a range of attractive interactions (van der Waals, π-π, hydrogen bonding, or solvophobic) in addition to Coulombic forces. Notably too, ion-ion interactions in ILs are tuneable, because changes in anion/cation size, shape or functional groups alter the balance of inter-ionic forces. These features suggest different solvent structures may be present in ILs compared to molecular solvents or molten salts. Further, many IL ions (usually the cation) are amphiphilic with both charged and uncharged groups. This means that there is potential for self-assembly in a fashion similar to aqueous surfactant dispersions, microemulsions or liquid crystals, but on much smaller length scales. Recent experimental and theoretical research has tested this hypothesis for aprotic ILs. The results show that aprotic ILs are heterogeneous on the nanoscale, forming polar and apolar domains in the bulk liquid due to clustering of charged and uncharged molecular groups. In this Thesis, the nature of protic IL structure in the bulk phase is examined using model fits to neutron diffraction data. It is shown that protic ILs are nanostructured solvents and that the solvent structure can be controllably varied. Secondly, aprotic IL structure at the Au(111) electrode interface are elucidated using atomic force microscopy. This provides fundamental insight to the IL electrical double layer structure that will underpin future IL-based electrochemical technologies.

▼ Ionic liquids have been studied as a possible solvent in a carbon capture process to reduce the CO2 emissions from coal-fired power plants and to replace conventional aqueous amine solvents. This study examines the reactive properties of amine functionalized ionic liquids and their use as a solvent for absorbing CO2. A post-combustion absorber is normally operated around 40°C and a pre-combustion process could be operated at even higher temperatures. Therefore, this work determines how the ILs behave at temperatures above room temperature in the presence of CO2. Aprotic heterocyclic anion (AHA) ILs are promising solvents to capture CO2 due to their ability to react equal molar with CO2 and their ability to be tuned for specific applications. Second order reaction rate constants were measured between 22 and 50°C for four different anions paired with the [P66614] cation. It was found that the reaction rate constant varied from 2100 L/mol/s to 18000 L/mol/s and can be estimated from the ΔHabs-CO2. The second order rate constant is linear with the ΔHabs-CO2, where the anions that more strongly bind with CO2 have a faster reaction rate than anions that weakly bind CO2. The calculated activation energies were surprising. [4-Triaz]- and [BrBnIm]- had similar activation energies to previously studied ILs (< 20 kJ/mol); however, [BnIm]- and [Inda]- had activation energies greater than 40 kJ/mol. The high activation energies are comparable to aqueous MEA solutions, however the reaction mechanism is much different. The effect of the cation on the reaction rate is also studied. It is found that the second order rate constant increases when the cation is changed from a tetra-alkyl phosphonium to a tetra-alkyl ammonium cation, which could be due to interactions between the anion and cation of the IL. The IL + CO2 reaction pathway was studied at high temperatures to explain the high Ea measured for [BnIm]- and [Inda]-. At room temperature the ILs chosen in this study react with CO2 to form a carbamate product. It was found that as the reaction temperature is increased, a second reaction channel competes with the carbamate formation. The cation is not an innocent bystander to the reaction and actually reacts with CO2 as well, due to the phosphonium cations having an acidic proton. The acidic proton on the α-carbon of the tetra-alkyl chain of the phosphonium cation is deprotonated by the basic anion forming an ylide. The ylide is then free to react with CO2. By changing the cation to an ammonium based cation, the ylide formation is kinetically suppressed and only the carbamate product is formed. This study gives insight into how the IL would react with CO2 in an actual absorber column. The use of multiple amines and additives is used to try and improve the CO2 capacity in ionic liquids. [P66614][dipyrrole-ketone] was tested to show greater than 1 : 1 molar uptake at 1 bar. Water and alcohols were added to ILs and shown to modify the reaction chemistry. The addition of the –OH groups in water and alcohol… Advisors/Committee Members: William A. Phillip, Committee Member, Joan F.
