Tuning of the undoped–doped color contrast can be obtained in poly(3‐hexylthiophenes) through the electropolymerization of oligomers of different length and regiochemistry. The regiochemistry affects the optical properties of the materials and molecular design allows the production of complementary electrochromic materials for variable light transmission devices.
