The new fluorocarbon-functionalized and/or heterocycle-modified polythiophenes, in particular, alpha,omega-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<SUP>2 </SUP>Vs-some of the highest reported to date for n-type organic semiconductors.
