Polyalkylthiophenes as electrochromic materials: A comparative study of poly(3-methylthiophenes) and poly(3-hexylthiophenes)


  • This research was funded by a grant from CNR, Progetto Finalizzato Materiali Speciali per Tecnologic Avanzate.


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.
