The synthesis of a novel electron-deficient fused pyrrolo[3,2-d:4,5-d']bisthiazole is reported from 2-bromothiazole. This was copolymerized with thiophene, selenophene, thienothiophene, and bithiophene by microwave-assisted Stille polycondensation. The resulting polymers exhibited small optical band gaps combined with low-lying HOMO energy levels and demonstrated semiconducting behavior in organic field effect transistors.
