| Outline of Final Research Achievements |
Recent years have witnessed an ever-growing interest in the bottom-up synthesis of nanocarbon molecules because it brings about an in-depth understanding of the unique structure-property relationships. However, it remains a formidable challenge to design and synthesize curved nanocarbon molecules in a rational way. To address this challenge, we have introduced a new concept for the design of nanocarbon molecules that used 1,3,5-trisubstituted benzene (phenine) as a basic trigonal planar unit. By adopting a synthetic strategy to utilize coupling reactions between phenine units, we successfully synthesized varios curved nanocarbon molecules including bowl-, saddle-, cylinder- and hemispherical-shaped nanocarbons.

| Academic Significance and Societal Importance of the Research Achievements |
フラーレンやカーボンナノチューブに代表されるナノカーボンは，強い・軽い・しなやかを兼ね備えた構造材料として幅広い応用が期待されている．しかしながら，これらナノカーボンは様々な構造の「混合物」であり，このことが構造に基づく物性の理解を妨げていた．本研究では，一義的構造を有する「分子」として，湾曲構造を有するナノカーボン分子を合理的に設計・合成するため戦略を確立した．原子レベルで構造が制御されたナノカーボン分子の物理的性質・化学的性質を解き明かすことで，湾曲ナノカーボン分子が有する構造的特長・物性を明らかにすることが出来た．
