We report the synthesis and characterization of novel bistetracenes, an unconventional, linearly extended conjugated core with eight fused rings. Also described are bisoligoacenes. In general, the properties and stability of large polycyclic aromatic hydrocarbons (PAHs) strongly depend on the mode of ring annellation and the topology of their it-electron systems, which are usually associated with the resonance stabilization energy in large PAHs.
我们报告了新型双四烯的合成和特性。双四烯是一种非常规的线性延伸共轭内核,具有八个融合环。此外还介绍了双
靛红烯。一般来说,大型多环
芳烃(PAHs)的特性和稳定性在很大程度上取决于环的环化模式和其电子系统的拓扑结构,这通常与大型多环
芳烃的共振稳定能有关。
