Outline of Final Research Achievements

An ionic liquid has been developed that transforms into an amorphous coordination polymer when exposed to ultraviolet light and returns to liquid form when heated. The solid-liquid transformation is fully reversible. The ionic liquid contains a cationic ruthenium sandwich complex with cyano groups. This study reveals a method that creates coordination polymers by exposing liquids to light.
