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 π−π stacking
我们报告了噻吩[2,3- f:5,4- f '] bis [1]苯并噻吩和噻吩[3,2- f:4,5- f '] bis [1]苯并噻吩的纯异构体合成。防和顺式由交替的噻吩和苯环的五环化合物的异构体。两者的光学和电化学性质均已报道。在反异构体中,三个噻吩单元的带状嵌入会导致近平面分子在固态下具有良好的π-π堆积行为,如X射线晶体结构分析所示。
