The new fluorocarbon-functionalized and/or heterocycle-modified polythiophenes, in particular, α,ω-diperfluorohexylsexithiophene DFH-6T can be straightforwardly prepared in high yield and purity. Introduction of such modifications to a thiophene core affords enhanced thermal stability and volatility, and increased electron affinity versus the unmodified compositions of the prior art. Evaporated films behave as n-type semiconductors, and can be used to fabricate thin film transistors with FET mobilities ˜0.01 cm

噻吩DFH-6T可以直接制备高收率和高纯度。将这样的修饰引入到
噻吩核心中可提供比先前未经修改的组合物具有增强的热稳定性和挥发性,以及增加的电子亲和力。蒸发薄膜表现为n型半导体,并可用于制备具有FET迁移率约0.01 cm2/Vs的薄膜晶体管-这是迄今为止报道的n型有机半导体中最高的之一。
