The solvation properties of some room-temperature ionic liquids consisting of imidazolium cations and various anions were examined by means of the high-pressure spectroscopy with solvatochromic probes. We measured the pressure dependence of KamletTaft solvatochromic parameters (π∗, β) and microviscosity (η). It was found that π∗ and β were not so sensitive to the types of imidazolium cations an...

The structural and molecular mechanism of double-stranded DNA (dsDNA) and single-stranded DNA (ssDNA) solvation in ten room-temperature ionic liquids (RTILs) is disclosed herein. We show that the Drew Dickerson B DNA structure solvated in neat RTILs based on imidazolium, oxazolium, pyrrolidinium, pyrimidinium and quaternary ammonium cations, combined with hexafluorophosphate and tetrafluorobrom...

The synthesis and decolorization of chiral room-temperature ionic liquids based upon 1-methyl imidazole and chloromethyl menthyl ether is reported. The excellent optical quality of these solvents permits the investigation of the effects of the two enantiomers on the excited-state photophysics of (S)-N-methyl-2-pyrrolidinemethyl 2(S)-(6-methoxy-2-naphthyl)propionate [(S,S)-NPX-PYR]. Whereas in c...

Ionic liquid (IL)-stabilized non-spherical gold nanofluids have been synthesized by a one-step method in aqueous solution. The whole reaction proceeded in room temperature. In the presence of amino-functionalized ionic liquids, gold nanofluids with long-wave surface plasmon resonance (SPR) absorption (>600 nm) could be obtained by adopting tannic acid as the reductant. The specific SPR absorpti...

Ionic Liquids are salts that are liquid at (or just above) room temperature. They possess several advantageous properties (e.g. high intrinsic conductivity, wide electrochemical windows, low volatility, high thermal stability and good solvating ability), which make them ideal as non-volatile electrolytes in electrochemical sensors. This mini-review article describes the recent uses of ionic liq...

We present a new family of metal based ionic liquids (MetILs) for use in flow battery applications. These materials are synthesized in a single step by simply heating a metal salt in the presence of a ligand containing multiple polarizable functional groups. The utility of this reaction has allowed a wide range of metal cation, anion and ligand combinations to be prepared and electrochemically ...

The temperature-dependent fluorescence anisotropy decay (orientational relaxation) of perylene and sodium 8-methoxypyrene-1,3,6-sulfonate (MPTS) were measured in a series of 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide (alkyl = ethyl, butyl, hexyl, octyl) organic room temperature ionic liquids (RTIL). The two fluorescent probe molecules display markedly different rotational dy...

Research on nonaqueous microemulsions containing ionic liquids as polar and/or apolar phase, respectively, is growing at a fast rate. One key property of ionic liquids that highlights their potential and their diversification compared to water is their wide liquid temperature range. In this emerging-area review article we survey recent developments in the field of nonaqueous micellar solutions ...
