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 cm2/Vs—some of the highest reported to date for n-type organic semiconductors.

A new family of perfluoroarene-modified thiophene semiconductors 1-3 has been synthesized to assess the influence of perfluoroarene introduction and regiochemistry on molecular and thin-film transistor properties. Compound 1 is an n-type semiconductor wit

The reactions of pentafluorobenzenesulfonyl chloride with benzene and thiophene derivatives in the presence of a ruthenium(II) catalyst proceeded at 240°C, with extrusion of sulfur dioxide and hydrogen chloride, to give the corresponding perfluorophenylated compounds.
