AI 要約（直近 5 年の研究成果）

本研究室は、有機半導体分子の結晶構造を精密に制御することで、電子デバイスの性能を大きく向上させることを目指しています。特に、芳香族化合物の特定位置に硫黄を含む置換基を導入する化学修飾に注目し、この簡単な分子変化が結晶内での分子配列をどのように変化させるかを詳細に調査しています。結晶構造の違いが電子移動度や電気伝導性に与える影響を、単結晶トランジスタの測定と理論計算の両面から解析する手法を採用しています。これまでの研究から、特定の置換基パターンが「レンガ積み」や「ピッチ積み」といった特殊な結晶配列を安定化させることが明らかになり、こうした構造を持つ分子は極めて高い電荷移動度を示すことが報告されています。さらに本研究室では、異なる元素（酸素、硫黄、セレン）を置換基に組み込むことで、結晶構造がどのように変わるかを系統的に比較する研究も進めています。また計算機シミュレーションにより有望な分子構造を事前に予測した上で合成することで、実験効率の向上も図っています。
