Outline of Final Research Achievements

Photochromic ionic liquids containing spiropyrans were developed. The salts containing cationic spiropyrans were synthesized and their thermal properties and photochromic properties were revealed. The relationship between the reaction cavity of crystal structure and crystalline-state photochromism of the salts were investigated. Binary ionic liquid mixtures of spiropyrans and onium salts were also prepared, and their liquid properties and photochromic behaviors were investigated.

Academic Significance and Societal Importance of the Research Achievements

フォトクロミック分子骨格を有するイオン液体はこれまで内外で盛んに研究されてきたが、静電相互作用変化を伴った光異性化を示す本系は原理が大きく異なる。したがって、光による多彩な液体物性の変化が期待される。このような液体は、多彩な物性研究の新対象となるだけでなく、機能溶媒用途といった応用展開にもつながる。
