| Outline of Final Research Achievements |
In recent years, non-planar extended pi-conjugated compounds have attracted great attention because of their unique physical properties and functions originated from steric distortion and chirality. However, due to the large distortion and steric hindrance of these compounds, the synthesis of designed new compounds is often challenging. Therefore, in this study, we examined the development of new highly active transition-metal complexes as catalysts and their application to the synthesis of novel non-planar extended pi-conjugated compounds. As a result, we succeeded in synthesizing various new non-planar extended pi-conjugated compounds (helicenes, cyclophanes, cycloparaphenylenes, etc.). We also succeeded in their catalytic asymmetric syntheses and chemical modifications that allow their organization and assembling.

本研究で開発した芳香環構築反応は、我々の研究グループが独自に開発した遷移金属錯体触媒を用いており、高い新規性と独創性を有している。これらの触媒反応を用いることで、これまで合成困難であった大きな立体障害や高い分子歪みを有する非平面型拡張パイ電子系化合物の合成が可能となった。合成された化合物群には、特異なパイ共役系をもつ化合物や、優れた円偏光発光特性を示す化合物などが見いだされている。さらに、開発された新触媒は、合成が簡便かつ高い安定性を有し実用性が高いだけでなく、その広い適用範囲から幅広いステージでの利用が期待できる。このように本研究成果は、高い学術的意義や社会的意義を有している。
