| Outline of Final Research Achievements |
In this research, we aim to synthesize the precursor that can form cyclacene skeleton and achieve the target cyclacene by the reaction that is stimulated by mild condition such heat and/or light energy instead of chemical reaction. When the norbornadiene skeleton was selected as the starting material for the targeted cyclacene skeleton, we succeeded in synthesizing a bromohexacene precursor, which is a planar extension structure of the cyclacene skeleton. However, it was difficult to synthesize a precursor with a small ring size by this method, so reaction with norbornadiene-2,3,5,6-tetradiene was tried, but the corresponding cyclacene precursor could not be synthesized. . In the future, it has become an issue to consider the synthesis of cyclacene skeleton by multistep reaction.

| Academic Significance and Societal Importance of the Research Achievements |
新規カーボン材料は実用化を見据えた研究が数多くなされ、その分野もバッテリー、キャパシタや半導体等の蓄電・導電材料、太陽電池や光触媒等の光電材料、熱伝材料や分子フィルター等、応用は幅広い。シクラセンはジグザグ型ナノチューブの基本骨格で、この分子の合成法と物性が明らかにされれば選択的ナノチューブの合成が可能となるが、未だ合成が達成されていない化合物である。本研究によりシクラセンへの合成と物性が明らかにされれば、ジグザグ型ナノチューブの基本骨格分野の新領域が開拓される。
