Outline of Final Research Achievements

Recently, we have succeeded in the short-step synthesis of BN-embedded tetrabenzocorannulene using the tandem bora-Friedel-Crafts reaction. Firstly, we have developed a one-shot borylation reaction that enables the facile boron substitution into various aromatic hydrocarbons. The regioselectivity is controlled kinetically: the borylation takes place at the least sterically hindered carbon where the HOMO is located. Secondly, based on this methodology, we have successfully synthesized various extended π-conjugated molecules, which are substructures of BN-containing carbon nanotubes.

Academic Significance and Societal Importance of the Research Achievements

本研究で合成した様々な含BN拡張π共役分子は,優れた発光特性や導電性といった機能を有しており,有機エレクトロニクス分野の発展に寄与するものと考えられる。また研究を通じて確立したone-shotホウ素化反応を応用し,含BNバッキーボウルや含BNカーボンナノベルトを合成することが可能であり,これらをテンプレート分子として用いた含BNカーボンナノチューブのボトムアップ合成への展開が期待できる。
