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 with a mobility approaching 0.1 cm2V -1s-1 whereas 2 and 3 exhibit p-type behavior. These results show that the origin of n-type carrier mobility is not solely a consequence of solution/film LUMO and HOMO energies.
