Der volle Inhalt der QuelleEnantioselective liquid-liquid extraction (ELLE) is an implementation of the extraction of one enantiomer from a racemic mixture by the transfer between two liquid phases. This technology is very promising for obtaining enantiopure compounds and becomes the object of much attention in recent years after the development of appropriate equipment that reduces the time and cost of the separation of enantiomers. The major objective for the successful introduction of ELLE to industrial world is the discovery of reliable, inexpensive and durable chiral hosts selective for a wide range of chiral substances. In this work the possibility of performing ELLE in chiral ionic liquids environment was verified. Many new chiral ionic liquids were prepared to play the role of chiral hosts. The best example shows enantiomeric excess of 30% and operational selectivity of 1. 97. This represents the first example of using chiral ionic liquids in ELLE and without metallic ions

Der volle Inhalt der QuelleJonvätskor möjliggör nya tillvägagångssätt för att kontrollera interaktioner vid gränsskiktet mellan fasta ytor och vätskor. Jonvätskor definieras som vätskor som består av stora och asymmetriska joner med en smältpunkt under 373 K. På grund av sin amfifila karaktär är de starka lösningsmedel men har också andra intressanta egenskaper. Jonvätskor kan till exempel självorganisera sig och attraheras till ytor på grund av sin laddning. En följd av detta är att de bildar nanostrukturer både i bulk och på ytor. Denna avhandling beskriver hur gränsskiktet mellan fasta ytor och jonvätskor svarar på yttre påverkan såsom en ökning i temperatur, tillsättning av ett salt samt polarisering. En ökad förståelse för hur dessa faktorer styr ytkompositionen av jonvätskor kan bidra med verktyg för att kontrollera system till specifika applikationer såsom friktion. Normala- och friktionskrafter mäts för etylammonium nitrat (EAN) mellan en glimmeryta och en kolloidprob vid olika temperaturer eller saltkoncentrationer. Resultaten visar att en ökning av temperatur eller låga koncentrationer av tillsatt salt bara marginellt framkallar ändringar i strukturen på gränsytan och att det adsorberade lagret förblir intakt. När saltkoncentrationen emellertid var tillräckligt hög får den mindre litiumjonen överhanden och ytsammansättningen ändras. Ytlagret av en liknande jonvätska undersöks också vid tillsättning av salt och resultaten avslöjar att litiumjoner påverkar ytsammansättningen annorlunda beroende på jonstrukturen av jonvätskan. Detta visar att ytselektiviteten starkt beror på jonkemin. En repulsiv dubbellagerkraft yttrar sig anmärkningsvärt för EAN vid 393 K vilket inte observeras vid lägre temperaturer. Detta indikerar en ändring i EANs mikroskopiska sammansättningsbeteende och har generella återverkningar för hur jonvätskor uppfattas. En ny metod har utvecklats baserad på en kvartskristall mikrovåg för att undersöka hur ytsammansättningen av jonvätskor reagerar på polarisering. Denna metod visar att det adsorberade lagret av både en ren jonvätska och en jonvätska löst i olja kan kontrolleras genom att applicera spänningar med olika tecken och storlekar. Dessutom möjliggör metoden två oberoende tillvägagångssätt för att övervaka laddningarna under polarisering vilket kan användas för att kvantifiera ytsammansättningen. Tekniken ger också information om jonkinetik och ytselektivitet. Detta arbete bidrar till den grundläggande förståelsen av gränsskiktet mellan fasta ytor och jonvätskor och visar att ytsammansättningen av jonvätskor kan kontrolleras och övervakas med olika tillvägagångssätt.

Der volle Inhalt der QuelleThe last decade of the 20th century has yielded a remarkable progress in the field of first generation artificial blood substitutes. Emulsions based on perfluorocarbons (PFCs) became one of the main candidates for a safe and reliable artificial blood substitute. The final objective of the present work is to study the fluorinated ionic liquids (FILs) with the purpose of replacing, partially or totally, the PFCs actually used as artificial blood substitutes, thus providing new fluids with tailored advanced properties. With this goal in mind, the thermophysical and thermodynamic characterization of several FILs, was carried out with the aim to select the most appropriate candidate. This characterization involves the measurement and analysis of the decomposition and melting temperature, density, viscosity, refractive index, and ionic conductivity at atmospheric pressure in a temperature range from 298.15 to 353.15 K. Furthermore, the liquid-liquid equilibria of binary mixtures of PFCs and FILs were studied, at atmospheric pressure in a temperature range usually from 293.15 to 343.15 K. The knowledge of the phase behaviour is crucial to the formulation of emulsions used nowadays as suitable oxygen carriers. Finally, Non-Random Two Liquid (NRTL) thermodynamic model was successfully applied to correlate the behaviour of the binary mixtures of PFCs and FILs

Der volle Inhalt der QuelleIonic liquid-supported Swern oxidation provided a new odorless approach to oxidize primary and secondary alcohols into aldehydes and ketones as compared to the conventional method where DMSO was used as an oxidant and the toxic and volatile compound dimethylsulfide was generated quantitatively. The new ionic liquid-supported organosulfur reagents were thermally stable, nonvolatile and odorless, which were recoverable and recyclable after Swern oxidation.
Chapter 3 of this thesis described the first example in the research field of ionic liquidsupported oligosaccharide synthesis. This new approach possesses the advantages of both conventional solution phase synthesis and solid phase-supported synthesis. It made possible the chemical assembling of glycals and the cleavage of oligosacharide from the support without need of chromatography to purify the products.
Ionic liquid-type oligomers were designed to solve the problems involved in the oneionic-unit ionic liquid-supported biopolymer synthesis because these compounds could have stronger ionic effects on support-bound molecules, which made easier the chemical assembling and purifications of large biopolymers than one-ionic-unit ionic liquidsupported organic synthesis. The thermogravimetric analysis (TGA) showed that these imidazolium oligomers have very good thermal stability. They also have great potential application in the electrochemistry.
Imidazolium oligomer-supported peptide synthesis provided a new approach to prepare peptides in a straightforward way. The amino acid coupling reactions were conducted in homogeneous solution phase, which did not require largely excess of reagents to push the reaction to completion and the purification could be performed in a simple way such as centrifugation, decantation and washing without need of special solvents. Moreover, the cleavage of the peptide from the imidazolium oligomer support was done by hydrolysis under basic conditions and the product was obtained in NMR and MS purity. Importantly, imidazolium oligomer-supported peptide block coupling proceeded very well, which provided an approach to convergently synthesize peptides. This approach is very useful for the peptide synthesis in industry especially for the synthesis of peptides with less than 20 amino acids.

Der volle Inhalt der QuelleRadioactive waste treatment is a crucial problem nowedays. This work was dedicated to the development of the new extracting systems for radionuclides on the basis of "green" solvents Ionic Liquids {Ils). For this purpose Ils were functionalized with various extracting patterns: phosphine oxide, carbamoyl phosphine oxide groups and malonamide fragment. Also the calix[4]arene platforms were used for the synthesis of functionalized ionic liquids (Fils) and their precursors. The Fils of both types cationic and anionic have been obtained. The synthesized Fils were tested for the liquid-liquid extraction of radionuclides. lt was found that extraction well occurs due to the extracting patterns, however a charge of a modified ion influences extraction.The various extracting experiments and mathematical modelling have been performed to determine the mechanisms of extraction. These studies showed that each extracting system is characterized by a different set of extracting equilibria, based mostly on cationic exchange

Der volle Inhalt der QuelleThe main objective of the present work is the application of aqueous biphasic systems (ABS) with ionic liquids (ILs) in the extraction of pharmaceutical wastes. Nowadays, after their expiration date time recovered medicine waste are incinerated, destroying most of the valuable compounds present, with only a minor thermic valorisation. Therefore the development of new processes that allow this wastes valorization is crucial to create a more environmentally friendly process and the use of wastes as a source of raw materials. The development of new ABS with ILs and their study allowed the optimization of the extraction of paracetamol and caffeine. Finally the application of this simple and fast process to a medical waste (ALGIK) resulted in a complete extraction of both paracetamol and caffeine.
Este trabalho tem como objetivo estudar a aplicação de sistemas aquosos bifásicos (SAB) com líquidos iónicos (LIs) na extração de compostos ativos de resíduos farmacêuticos. Atualmente os medicamentos fora do mercado são recolhidos e incinerados, sendo por isso a totalidade dos compostos ativos de interesse perdidos por combustão completa. Apesar da valorização energética destes resíduos há grandes perdas ao nível dos vários compostos presentes. Deste modo o desenvolvimento de novos processos simples de extração com vista a’ valorização dos compostos ativos presentes nos mesmos é de grande importância, minimizando os impactos ambientais e permitindo a utilização destes resíduos como fonte de matérias primas. Foi possível desenvolver novos SAB com LIs e proceder ao estudo e otimização dos mesmos na extração de cafeína e paracetamol. Por fim o processo otimizado foi aplicado a um resíduo medicamentoso (ALGIK). O resultado obtido demonstra uma completa extração dos compostos ativos com os SAB utilizados.

Der volle Inhalt der QuellePotential electrolytes for dye-sensitized photoelectrochemical solar cells have been synthesized and their applicability has been investigated. Different experimental techniques were used in order to characterize the synthesized electrolytes, such as elemental analysis, electrospray ionisation/mass spectrometry, cyclic voltammetry, dynamic viscosity measurements, as well as impedance, Raman and NMR spectroscopy. Some crystal structures were characterized by using single crystal X-ray diffraction.
In order to verify the eligibility of the ionic compounds as electrolytes for photoelectrochemical solar cells, photocurrent density/photovoltage and incident photon-to-current conversion efficiency measurements were performed, using different kinds of light sources as solar simulators. In electron kinetic studies, the electron transport times in the solar cells were investigated by using intensitymodulated photocurrent and photovoltage spectroscopy. The accumulated charge present in the semiconductor was studied in photocurrent transient measurements.
The ionic liquids were successfully used as solar cell electrolytes, especially those originating from the diethyl and dibutyl-alkylsulphonium iodides. The highest overall conversion efficiency of almost 4 % was achieved by a dye-sensitized, nanocrystalline solar cell using (Bu2MeS)I:I2 (100:1) as electrolyte (Air Mass 1.5 spectrum at 100 W m-2), quite compatible with the standard efficiencies provided by organic solvent-containing cells. Several solar cells with iodine-doped metal-iodidebased electrolytes reached stable efficiencies over 2 %. The (Bu2MeS)I:I2-containing cells showed better long-term stabilities than the organic solvent-based cells, and provided the fastest electron transports as well as the highest charge accumulation.
Several polypyridyl-ruthenium complexes were tested as solar cell sensitizers. No general improvements could be observed according to the addition of amphiphilic co-adsorbents to the dyes or nanopartices of titanium dioxide to the electrolytes. For ionic liquid-containing solar cells, a saturation phenomena in the short-circuit current densities emerged at increased light intensities, probably due to inherent material transport limitation within the systems.
Some iodoargentates and -cuprates were structurally characterized, consisting of monomeric or polymeric entities with anionic networks or layers. A system of metal iodide crownether complexes were employed and tested as electrolytes in photoelectrochemical solar cells, though with poorer results. Also, the crystal structure of a copper-iodide-(12-crown-4) complex has been characterized
