Temperature-dependent microscopic solvent properties of ‘dry’ and ‘wet’ 1-butyl-3-methylimidazolium hexafluorophosphate: correlation with ET(30) and Kamlet–Taft polarity scales

Solvatochromic Study on Binary Solvent Mixtures with Ionic Liquids

“…Pyrene is one of the most widely used neutral fluorescence probes. Contrary to the results obtained from probe studies with Reichardt's dye (1), the exited state of pyrene clearly indicates a completely different micro-environment [13]. Such a complexity suggests for solvent-dependent processes the use of a multi-parameter description with various solvatochromic parameters as part of them.…”

Effect of added ionic liquid on aqueous Triton X-100 micelles

“…Apart from the fact that ILs are constituted of cations/anions and are still in the liquid state at the ambient, most of the recent investigations with ILs are driven by the possibility of their potential environmentally-benign nature; they possess almost negligible vapor pressure and can be recycled easily. As a consequence, it is logical to employ these ILs in concert with other environmentally-friendly systems such as, supercritical fluids [20][21][22][23][24][25][26], aqueous [27][28][29][30][31][32][33][34] and polymer [35][36][37][38][39] solutions, surfactant-based systems [40][41][42][43][44][45][46][47][48][49][50][51], etc.…”

Solvatochromic absorbance probe behavior within 1-butyl-3-methylimidazolium hexafluorophosphate+propylene carbonate: Preferential solvation or solvent–solvent interaction?

“…Among the approaches to enhance solute solubility within ILs and to modify physicochemical properties of ILs in desirable fashion, addition of cosolvent(s) or mixing two or more ILs appears both simple and effective [12][13][14][15][16][17][18]. Towards this end, we have previously reported our investigations on the effects of added water [12,13], ethanol [14], aqueous-ethanol [15], poly(ethylene glycol)s [19], and other ILs [16] on a common and popular IL 1-butyl-3-methylimidazolioum hexafluorophosphate ([bmim][PF 6 ]).…”
