Research Abstract

自己集合性のポルフィリンが与えるπ空間にフラーレンなどのπ系分子を包接・配列させることによって、新規の機能性π複合体を構築することを目的とする。特に、ポルフィリンがドナー、フラーレンがアクセプターとなる光誘起電荷分離状態は、長寿命を有することが知られており、ポルフィリン・フラーレンのπ複合体を高次π空間中で配列させることによって、前例を凌駕する高い効率の光電変換機能の実現が期待される。
具体的な研究項目を以下に列挙する。
(1)新規自己集合性ポルフィリン二量体の合成
(2)自己集合性ポルフィリン二量体へのフラーレン包接挙動の解析と複合体の構造解析
(3)ポルフィリン二量体-フラーレンのπ複合体の光化学ダイナミクス、電荷移動プロセス、光電変換特性の解析
