1.1.背景共轭有机化合物在新一代光电材料的开发中起着重要的作用。具有碳、杂原子或有机金属骨架的分子、低聚物和聚合物已经被广泛地探索作为电致发光、数据存储和非线性光学的介质。[1]研究最深入的富碳骨架共轭分子的特征是扩展的线性共轭π-体系。然而，还有其他π电子通讯模式，包括交叉共轭和全共轭2，也可以产生电子感兴趣的材料。
1.1. BackgroundConjugated organic compounds play a primary role in the development of a new generation of optical and electronic materials. Molecules, oligomers, and polymers with carbon, heteroatomic, or organometallic frameworks have been widely explored as media for electroluminescence, data storage, and nonlinear optics. 1 The most intensely studied conjugated molecules with carbon-rich frameworks feature extended, linearly-conjugated π-systems. There are, however, alternative modes of π-electron communication, including cross conjugation and omniconjugation 2 that can also produce electronically interesting materials.
