n-Type conjugated polymers comprising bithiophene imide and multifluorinated thiophene moieties synthesized by direct arylation polycondensation

n-Type conjugated polymers were synthesized by environmentally benign direct arylation polycondensation. With these polymers, OTFTs with μ e of up to 0.72 cm 2 V −1 s −1 were fabricated.
