Outline of Final Research Achievements |
The purpose of this research is to develop new organic ferroelectric materials and establish a theory that expresses its properties by taking advantage of the structural characteristics of graphene nanoribbons (GNRs) that have one-dimensionally long pi-conjugated skeleton. While many inorganic ferroelectric substances are known, organic substances are limited to organic polymers such as polyvinylidene fluoride. On the other hand, we have synthesized asymmetrically-substituted GNRs having a large dipole moment within the molecule can be synthesized by asymmetrically modifying the edges with limited fluctuation and a rigid skeleton, And then, we investigated the electronic and physical properties derived from its structure.

Academic Significance and Societal Importance of the Research Achievements |
グラフェンやカーボンナノチューブなど新たなナノ炭素物質が光電子材料として優れた性質をもつことが明らかになっているが、機能性材料として応用された例は限られる。グラフェンやナノチューブはその構造から、置換基の付与は困難であるのに対し、GNRは一次元状物質でありエッジを適切に修飾することによりさらなる機能性の付与が可能である。本研究で得られた手法を用いさらなる誘導化を進め材料化学分野へと展開していくことで、ナノ炭素材料の一つであるグラフェンナノリボンの化学の発展に寄与できるものと期待できる。
