The use of ionic liquids as functional building blocks based on pyridinium, imidazolium and phosphonium cations to achieve materials combining a structuration at nanoscale with the dramatic mechanical properties of the resulting ionomers has been successfully demonstrated for the first time in a fluorinated matrix.

Surface active amide-functionalized ionic liquids (ILs) consisting of a long alkyl chain (C6C14) connected to a polar head group (methylimidazolium or pyridinium cation) via an amide functional group were synthesized and their thermal stability, micellar properties and antimicrobial activity in aqueous solution investigated. The incorporation of an amide group increased the thermal stability of...

Title of Document: PHOTOINDUCED ELECTRON TRANSFER IN IONIC MEDIA Rebecca Cristine Vieira, Doctor of Philosophy, 2008 Directed By: Dr. Daniel E. Falvey, Department of Chemistry and Biochemistry The goal of this research was to explore the use of room temperature ionic liquids (RTILs) and ionic liquids crystals (ILCs) as reaction media for photoinduced electron transfer (PET) processes. Photoindu...

This study investigated the retention mechanism of a congeneric group of imidazolium ionic liquid cations with alkyl functional groups of different lengths, an aryl substituent, and one pyridinium cation on a pentafluorophenylpropyl silica-based stationary phase. The influence of organic modifier type and content in the mobile phase on the retention mode of alkylimidazolium ionic liquid cations...

The separation of the nonaqueous azeotropic systems methyl acetate−methanol and ethyl acetate−ethanol was investigated with 13 cations and 27 anions as entrainers to identify suitable ionic liquids using the COSMO-RS model. It is observed that the cations best suited are imidazolium > pyridinium > methyl pyrrolidinium > octyl quinolinium. The lengthening of the alkyl chain of cations was also s...

Interest in ionic liquids for their potential in different chemical processes is constantly increasing, as they are claimed to be environmentally benign – excellent, nonvolatile solvents for a wide range of applications. The wide applicability of these compounds also demands reliable, relatively simple and reproducible analytical techniques. These methods must be applicable not only to differen...

A series of imidazolium and pyridinium-based bridged dicationic ionic liquids have been analysed using X-ray photoelectron spectroscopy. The different electronic environments the dications investigated a robust fitting model for carbon C1s region has also developed. relative positions components N1s determined their complex photoemission spectra produced from both aromatic aliphatic states givi...
