A semiconducting polymer bearing the thiazolothiazole moiety in the polythiophene backbone (see figure) is synthesized. The polymer is found to have small bandgap and large ionization potential. Despite the low molecular weight, the polymer exhibited a high field-effect mobility after annealing. A high on/off ratio suggests the polymer possesses high stability against oxygen doping. The polymer device also showed good environmental stability.
