We have synthesized a series of novel coplanar chromophores in which heteroarenes, namely, thiophene, benzothiophene, and carbazole, were fused to neighboring phenylene ring(s) through intramolecular annulation via sp(3)-hybridized carbon atoms bearing two p-tolyl groups as peripheral substituents. The molecular configurations of the pi-conjugated backbones were determined by X-ray crystallographic analysis; the heteroarene-fused molecular frameworks of these novel molecules exhibit nearly coplanar conformations.

我们合成了一系列新型共平面发色团，其中杂芳烃，即噻吩、苯并噻吩和咔唑，通过分子内环合，经由带有两个对甲苯基作为外围取代基的sp(3)杂化碳原子与相邻的亚苯基环稠合。通过X射线晶体学分析确定了π共轭主链的分子构型；这些新型分子的杂芳烃稠合分子骨架呈现出近乎共平面的构象。[结构：见正文]
