| Outline of Final Research Achievements |
I designed ligands that can absorb visible light and induce redox of coordinated transition metals by TD-DFT calculations. Synthesis of the designed ligands was actually performed. Seven ligands were successfully synthesized, and all of them were found to be able to absorb visible light. For some of the ligands, I succeeded in isolating them in a stable state as transition metal complexes and proved their structures by NMR measurements and X-ray crystal structure analysis.
We have also succeeded in finding unique reactions that do not proceed with existing common ligands.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって、可視光をエネルギー源とした特異な化学反応が新たに可能となった。光は宇宙空間より無尽蔵に降り注ぐエネルギーであるため、有限な地球上の資源を用いる必要がないグリーンなエネルギー源である。昨今SDGs(持続可能な開発目標: Sustainable Development Goals)の重要性が叫ばれているが、本研究は遷移金属を用いた化学反応に関するSDGs達成のための一助となる。さらに、化学変換そのものも既存の方法では非効率あるいは困難なものを効率的に実現しているため、エネルギーに関する側面だけでなく基礎研究としても発展的な研究成果である。
