Outline of Final Research Achievements |
In this study, we designed and synthesized fluorescent molecules based on a tetra(2-thienyl)ethylene scaffold, and fully characterized their emission properties. As the research results, we demonstrated that the synthesized fluorescent molecules (i) possess aggregation-induced emission (AIE) characteristics (that is, the enhancement of emission due to restriction of intramolecular motion upon the formation of aggregates), (ii) display various solid-state emission colors depending on their molecular structures, (iii) exhibit mechanofluorochromism (MFC), referring to the change in solid-state emission color in response to external mechanical stimuli.

Academic Significance and Societal Importance of the Research Achievements |
メカノフルオロクロミズム(MFC)特性を有する発光分子、すなわちMFC分子は、「センサー」や「メモリー」など機能性固体発光材料としての応用が期待され、注目されている。本研究では、テトラ(2-チエニル)エチレン骨格を基軸としたMFC分子ライブラリーを構築し、固体構造(分子配列と分子間相互作用)が寄与するMFC特性の発現と制御に必要な分子構造の電子的・構造的要因に関する知見を得た。本研究成果は、MFCメカニズムの解明とMFC分子設計のための重要な基礎データを提示し、将来のMFC材料開発へつながることが期待される。
