C. Arbizzani et al., POLYALKYLTHIOPHENES AS ELECTROCHROMIC MATERIALS - A COMPARATIVE-STUDYOF POLY(3-METHYLTHIOPHENES) AND POLY(3-HEXYLTHIOPHENES), Advanced materials, 7(6), 1995, pp. 571-574
Tuning of the undoped-doped color contrast can be obtained in poly(3-h
exylthiophenes) through the electropolymerization of oligomers of diff
erent length and regiochemistry. The regiochemistry affects the optica
l properties of the materials and molecular design allows the producti
on of complementary electrochromic materials for variable light transm
ission devices.
