Solvent and rotational relaxation study in ionic liquid containing reverse micellar system: A picosecond fluorescence spectroscopy study

► Preparation and characterization of ionic liquids containing reverse micelle. ► Nanoscopic confinement of ionic liquids by an interface slows down the dynamics of solvent relaxation. ► Greater the thickness of palisade layer of surfactant more affects the solvation dynamics of ionic liquids.
