Abstract

Ionic liquids are liquid salts at room temperature. Ionic liquids are composed only ions and have unique properties such as non-volatility and non-flammability even when heated under vacuum. Ionic liquids have been attracting much attention as an environmentally-benign “green solvent”. My group mainly works on development of electrolyte materials and synthesis of cellulose derivatives using ionic liquids.
