Outline of Final Research Achievements

The aim of this study is to develop meltable coordination polymers using ionic liquids. A series of anionic coordination polymers containing ionic liquid cations were synthesized by the reaction of ionic liquids and salts containing cyanide anions. These materials exhibited incongruent melting, and the mechanism was elucidated spectroscopically. Most of the coordination polymers vitrified upon rapid cooling from the molten state. The observed melting trends and vitrification conditions depended on the cation structure in the materials.

Academic Significance and Societal Importance of the Research Achievements

近年、融解する配位高分子がいくつか報告され、それらは加工性やガラス形成能の点で注目されている。本研究では、イオン液体を用いて低融点配位高分子を合成する方法論を開拓し、多成分からなる配位高分子における不一致融解現象の一般性を示した。これらの結果は、低融点配位高分子の物質設計およびガラス化能制御の指針として、今後の機能性配位高分子開発に有用である。
