Abstract

A novel nitrogen-functionalized curved superbenzene was prepared via oxidative cyclodehydrogenation of a suitable hexaarylbenzene precursor under mild conditions. The spectroscopic and electrochemical properties are detailed here and compared with those of permethoxylated hexa-peri-hexabenzocoronene. The crystal structure analysis confirmed that the molecule has an unequal ‘double-concave’ aromatic core due to the inclusion of a pyrimidine subunit and the steric encumbrance of the methoxy groups at the periphery.

含氮弯曲杂超苯的合成及性能

摘要

通过在温和条件下合适的六芳基苯前体的氧化环脱氢反应制得了一种新型的氮官能化的弯曲超苯。光谱和电化学性能在这里详细介绍，并与permethoxylated六相比周边-hexabenzocoronene。晶体结构分析证实该分子具有不相等的“双凹”芳族核，这归因于嘧啶亚基的引入以及外围甲氧基的空间保留。
