我们报道了噻吩并[2，3-f：5，4-f ']双[1]苯并噻吩和噻吩并[3，2-f：4，5-f ']双[1]苯并噻吩的异构体纯合成，它们是由噻吩和苯环交替组成的五环化合物的反式和顺式异构体。两者的光学和电化学性能的报告。在反式异构体中，三个噻吩单元的带状嵌入导致在固态下具有有利的π-π堆积行为的近平面分子，如通过X射线晶体结构分析所示。
We report isomer-pure synthesis of thieno[2,3-f:5,4-f ']bis[1]benzothiophene and thieno[3,2-f:4,5-f ']bis[1]benzothiophene, the anti and syn isomers of a pentacyclic compound consisting of alternating thiophene and benzene rings. The optical and electrochemical properties of both are reported. In the anti isomer, the ribbonlike embedding of three thiophene units leads to a near-planar molecule with favorable pi-pi stacking behavior in the solid state as shown by X-ray crystal structure analysis.
