01 / OVERVIEW

研究概要Research overview

発光性有機分子では、溶液中と固体中で発光特性が大きく変化することがあります。当研究室では、含フッ素トラン型分子やビストラン型分子、屈曲したπ共役分子などを対象に、固体状態での発光特性を研究しています。

フッ素置換の位置、電子供与基・電子求引基、分子骨格の形状、結晶中の分子集合の違いに着目し、発光波長と発光効率の制御を目指します。固体発光の研究成果を、発光フィルムなどへの展開にも結び付けています。

The luminescence of organic molecules often changes substantially between solution and the solid state. We study fluorinated tolane and bistolane derivatives, as well as bent π-conjugated molecules, to understand and control their solid-state photoluminescence.

We examine how fluorine substitution, donor–acceptor electronic balance, molecular geometry, crystal packing, and aggregation influence emission color and efficiency. These design principles also inform our exploration of luminescent films and related materials.
