Synthesis and Electrochromic Properties of Novel Oligothiophene Derivatives

Abstract:

In order to develop novel electrochromic materials, 2,3′:4′,2″-terthiophene (I3T), 5,5′-biformyl- 2,2′:5′,2″:5″,2″′-quaterthiophene (4T-2CHO), and 2,5-(5′-cyano)thienyl-3,4-thienyl-t- hiophene (XT-2CN) were synthesized, and their electrochromic properties were studied. It was found that I3T, 4T-2CHO and XT-2CN as solid films showed reversible, clear color changes on electrochemical doping and dedoping. These oligothiophene derivatives constitute a new class of potential electrochromic materials.
