A new concise approach for the construction of heteroatom analogues of polycyclic aromatic benzo[g]quinoline, benzo[b]carbazole, and pyrido[b]carbazole systems via diaryl methanols is described. This transformation involves formation of a central benzene ring fused to two aromatic 5- or 6-membered rings of pyrrole and/or pyridine by using a combination of two aromatic aldehydes, of which at least one contains a ring nitrogen. Analysis of the UV and fluorescent properties, Stokes shifts, quantum yields in solution, and pi-stacking interactions in the crystal structures of the new materials was performed. These polycyclic aromatic compounds show potential as small-molecule organoelectronic materials.
本文描述了一种通过二芳基甲醇构建稠环芳烃苯并[g]喹啉、苯并[b]咔唑和吡啶并[ b ]咔唑类似物的新简洁方法。该转化涉及通过使用两种芳族醛的组合形成中心苯环，该组合融合了两个吡咯和/或吡啶的芳族 5 或 6 元环，其中至少一种醛含有环氮。对新材料的紫外和荧光性质、Stokes 位移、在溶液中的量子产率以及晶体结构中的π堆积相互作用进行了分析。这些多环芳烃化合物有望成为小分子有机电子材料。
