We have established a series of synthetic methods to synthesize alkyl-substituted fused thiophenes with degrees of fusion from two to seven rings. These fused thiophene ring compounds have very good solubility in common organic solvents, making possible the solution processing of these compounds for electronic applications. The UV absorption of these fused thiophenes is blue-shifted when compared with
我们已经建立了一系列合成方法来合成烷基取代的稠合噻吩,其稠合度为两个到七个环。这些稠合的噻吩环化合物在常见的有机溶剂中具有非常好的溶解性,使得这些化合物的溶液加工成为电子应用成为可能。与它们的烃类对应物相比,这些稠合噻吩的紫外线吸收发生了蓝移。带隙越大,稳定性越好。3,6-didecanyldithieno [2,3- d:2',3'- d '] thieno [3,2- b:4,5- b '']二噻吩(FT5)的单晶X射线结果3,7-二癸基噻吩并[3,2- b ]噻吩并[2',3':4,5]噻吩并[2,3- d]噻吩(FT4)证明这两种化合物均形成π堆积结构,而不是人字形的堆积图案。这种更有利的π堆叠结构可以导致更好的材料电子性能,例如在用这些化合物制造的器件中的迁移率。
