Abstract
Soluble butterfly-shaped tetraazapentacenes and tetraazaheptacenes were prepared by condensation or Stille coupling with a stannafluorene. The stability of the benzo-winged tetraazaheptacene is dramatically increased through the fourfold benzannulation, yet its acene character is retained to a significant extent.
摘要
可溶性蝶形四氮杂并五苯和七氮杂并七苯通过缩合或 Stille 偶联与芴基锡反应制备。通过四重苯并环化，苯并 winged 七氮杂并七苯的稳定性显著提高，但仍在很大程度上保留了其并苯特征。
