Synthesis of belt-shaped fused conjugated molecule "pi belt": actualization as a key material in novel non-planar nano-carbon

本研究旨在合成一种带状稠合共轭分子(PI带)。以具有弯曲稠合苯环的碗状分子苏马烯为基块，设计了合成聚酰亚胺的策略。研究了苏曼烯单元的连接方法。苏马烯类化合物通过交叉偶联、氧化偶联和还原偶联三种途径偶联。发展了分子内脱氢氧化构建弯曲熔融结构的方法。

This study was conducted toward the synthesis of a belt-shaped fused conjugated molecule (pi belt). The strategy for the synthesis of pi belt was designed based on the use of bowl-shaped molecule sumanene with curved and fused benzene rings as a building block. The methods for linking the sumanene units were investigated. Sumanenes were coupled via three routes based on cross-coupling, oxidative coupling, and reductive coupling. The method to construct the curved and fused structure by intramolecular dehydrogenative oxidation was developed.
