Contrasting thermosolvatochromic trends in pyridinium-, pyrrolidinium-, and phosphonium-based ionic liquids.
Thermosolvatochromism has been studied in three series of ionic liquids and the polarity decreases with temperature in the case of pyridinium- and pyrrolid inium-based ionic liquid, and it increases withTemperature in the cases of phosphonium and alanate and valinate anions.

Polarity studies in two classes of imidazolium-based protic ionic liquids (PILs) possessing [HSO(4)](-), [HCOO](-), [CH(3)COO](-) and [CH(3)CH(2)COO](-) anions were carried out using a solvatochromic…
The cosolvent-directed Diels-Alder reaction in ionic liquids.
The Diels-Alder reaction of anthracene 9-carbinol with N-ethyl maleimide in binary mixtures of pyridinium-based ionic liquids demonstrates a successful application of the pairwise interaction model built upon the concept of enforced hydrophobic hydration.
Delineating solute-solvent interactions in binary mixtures of ionic liquids in molecular solvents and preferential solvation approach.
The preferential solvation models have been employed to analyze the collected data in order to achieve information on solute-solvent interactions in these binary mixtures to show nonideality on addition of ionic liquids to water and dichloromethane.
