Abstract: New, hydrophobic ionic liquids with low melting points (<−30 °C to ambient temperature) have been synthesized and investigated, based on 1,3-dialkyl imidazolium cations and hydrophobic anions. Other imidazolium molten salts with hydrophilic anions and thus water-soluble are also described. The molten salts were characterized by NMR and elemental analysis. Their density, melting point, viscosity, conductivity, refractive index, electrochemical window, thermal stability, and miscibility with water and organic solvents were determined. The influence of the alkyl substituents in 1, 2, 3, and 4(5)-positions on these properties was scrutinized. Viscosities as low as 35 cP (for 1-ethyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)amide (bis(triflyl)amide) and trifluoroacetate) and conductivities as high as 9.6 mS/cm were obtained. Photophysical probe studies were carried out to establish more precisely the solvent properties of 1-ethyl-3-methylimidazolium bis((trifluoromethyl)sulfonyl)amide). The hydrophobi...

Solvent-dependent fluorescence of pyrene-3-carboxaldehyde and its applications in the estimation of polarity at micelle-water interfaces
TL;DR: In this paper, the authors show that the fluorescence of pyrene-3-carboxaldehyde shows a strong dependence on solvent polarity, which is used to obtain estimates of the polarity at the micelle-water interfaces for various ionic and nonionic detergent micelles.

TL;DR: In this paper, the properties of aluminum chloride dissolved in fused mixtures of ethyl pyridinium bromide and metallic chlorides have been investigated, and it was found from melting point data that a compound having the composition is formed, and that a very low melting point (−40°C) occurs at 67 mole per cent.
Evidence for the presence of hydrogen-bonded ion-ion interactions in the molten salt precursor, 1-methyl-3-ethylimidazolium chloride
TL;DR: The crystal structure analysis and IR study of the 1-methyl-3-ethylimidazolium chloride (MEICl) has been undertaken as part of an investigation of the ion-ion interactions in room temperature melts, where the mole fraction of AlCl 3 is less than 0.5 as mentioned in this paper.
