Abstract
Four conjugated copolymers with a donor/acceptor architecture including 4,4-dihexadecyl-4H-cyclopenta[1,2-b:5,4-b']dithiophene as the donor structural unit and benzo[2,1,3]thiodiazole fragments with varying degrees of fluorination have been synthesized and characterized. It has been shown that the HOMO levels were decreased after the fluorine substitution. The field-effect charge carrier mobility was similar for all polymers with less than an order of magnitude difference between different acceptor units.
