Abstract
The synthesis of highly planar tetraaza[8]circulenes from tetrathia[8]circulenes through oxidation followed by a nucleophilic aromatic substitution reaction with arylamines is presented. Photophysical and electrochemical properties of tetraaza[8]circulenes were investigated and compared to those of tetrathia[8]circulenes. The tetraaza[8]circulene exhibited bright fluorescence both in solution and solid states.
摘要
本文报道了通过氧化反应将四硫[8]轮烯转化为高度平面的四氮[8]轮烯，然后与芳胺进行亲核芳香取代反应。研究了四氮[8]轮烯的光物理和电化学性质，并与四硫[8]轮烯进行了比较。四氮[8]轮烯在溶液和固态中均表现出明亮的荧光。
