Site selective probing of surfactant assemblies using excited state proton transfer of pyranine

Abstract

The thesis includes our investigations on the nature and behavior of water entrapped in the nano confined surfactant assemblies in particular reverse micelles and micelles The hydration behavior depends critically on the type of polar headgroup of surfactants and also on the presence of co surfactants We mainly employed the hydration sensitive excited state proton transfer ESPT property of a site selective anionic probe 8 hydroxypyrene 1 3 6 trisulfonate HPTS or pyranine to study these
