Tatsuo Yajima 研究室（関西大学）

AI 要約（直近 5 年の研究成果）

本研究室は、有機化学・無機化学・高分子化学の境界領域において、分子の電子状態と機能を精密に制御する研究を展開しています。特に、化学結合の酸化還元反応を利用して、分子の光学特性や触媒活性を制御することに注力しています。赤外線領域での光吸収を示す物質開発や、金属イオンと有機配位子が織りなす電子構造の詳細な解明が主要なテーマとなっています。具体的には、三次元的な分子構造設計により、一電子酸化還元で生成するラジカルカチオンが安定に存在する材料や、赤外線を吸収・発光する色素の開発を進めています。また銅やニッケルなどの遷移金属と有機リガンドの相互作用を分析し、複雑な酸化状態を持つ金属錯体の電子構造を実験的・理論的に解きほぐしています。さらに、設計した分子やポリマーを触媒や高機能材料として応用する研究も並行しており、有機合成反応の高効率化や光応答性ポリマーの開発など、基礎科学から実用化に向けた幅広いアプローチを採用しています。
