n-Type Thiophene Semiconductors

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.

Perfluorophenylation of aromatic and heteroaromatic compounds with pentafluorobenzenesulfonyl chloride catalyzed by a ruthenium (ii) phosphine complex

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.
