01 / OVERVIEW

研究概要Research overview

液晶性は分子の形状だけでなく、極性、分子間相互作用、末端基、柔軟鎖の構造などにも左右されます。当研究室では、含フッ素π共役骨格を基盤として、従来と異なる構造要素を導入した新規液晶分子を設計しています。

フッ素原子の導入位置や数、柔軟鎖の長さ、イミダゾールなどの末端構造を系統的に変化させ、液晶相の発現や相転移温度、光学的性質との関係を調べています。

Liquid-crystalline behavior depends not only on molecular shape but also on polarity, intermolecular interactions, terminal groups, and flexible-chain design. We develop new mesogenic architectures based on fluorinated π-conjugated frameworks.

By systematically varying fluorine substitution, chain length, and terminal functionalities, including imidazole-containing groups, we investigate how molecular structure governs mesophase formation, phase transitions, and optical properties.
