The rational structure optimization of a polythiophene containing benzo[2,1‐b;3,4‐b′]dithiophene on the molecular level leads to a polymer that is easily synthesized and processed. Fabricated on a flexible substrate, the polymer shows excellent device characteristics, good reproducibility, and charge‐carrier mobilities up to 0.5 cm 2 V −1 s −1 without annealing.
