Research Abstract

Ionic liquids are now being recognized as the third group of solvents, following water and organic solvents. They are easily available and possess unique properties such as nonvolatility, high thermal stability, high ionic conductivity, and designability, which make it possible to use them under extremely unusual conditions and on demand. This project has focused on the dynamics and dissociativity (ionicity) of ionic liquids. It is demonstrated that the magnitude of ionicity greatly affects the unique properties of ionic liquids. Task-specific ionic liquids are designed and prepared from the viewpoint of their utilization as neoteric solvents and electrolytes for new materials and devices.
