| Outline of Final Research Achievements |
By screening the borylating agents, additives, solvents, and reaction conditions in the tandem bora Friedel-Crafts reaction, we have developed regioselective and efficient multiple C-H borylation reactions. It allowed us to introduce up to 4 boron atoms to triarylamines in a highly selective manner. In addition, the precise synthesis of graphene nanoribbons with boron and nitrogen has been achieved by surface-assisted polymerization reaction on a gold substrate using dihydrodibenzo[b,e][1,4]azaborine with a 10-haloanthracene substituent as a precursor.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で合成された含BN拡張π共役分子は，一重項励起エネルギーと三重項励起エネルギーの差が小さく，色純度の高い青色蛍光を示すことから，熱活性化遅延蛍光材料として有用である。また，含BNグラフェンナノリボンは基板上で完全な平面構造をとっており，新たな導電材料，半導体材料としての応用が期待できる。加えて，本研究を通じて確立したホウ素化反応は汎用性に優れており，様々な含ホウ素機能性π共役ポリマーの開発の促進が期待できる。
