Outline of Final Research Achievements

We are interested in phenylenediamine-quinonediimine derivatives, which are organic compounds with nitrogen atoms capable of interacting with metals and reversibly changing their molecular states, achieving a mutual change of both oxidation and reduction states through interaction with metal atoms, as well as to use the change of state The research is to achieve the mutual change of both oxidation and reduction states of phenylenediamine and quinonediimine derivatives through the interaction with metal atoms and to use the change of state.
In the course of this study, the strength of the interaction with various metal species and the conversion from the oxidized state to the reduced state were investigated from a spectroscopic point of view. In the course of these studies, we have found that molecules can be converted from solutions containing only the oxidized state to the reduced state.

Academic Significance and Societal Importance of the Research Achievements

本研究で扱っているフェニレンジアミン・キノンジイミン誘導体は容易に合成が可能で、官能基導入による電子状態のチューニングやアミノ酸部位等の不斉構造部位の導入が可能であることから、適切な条件となるよう分子構造を設計することで、幅広い物質に対する酸化、または還元反応を温和な条件下で行うことができると考えられる。省エネルギー的物質変換を可能とする触媒分子の設計指針は、昨今の社会情勢から今後より一層重要度が高くなると考えられる。
