Synthesis and Electrochromic Properties Based on Star-Shaped Oligothiophene Derivatives with Phenyl Core
For the purpose of developing novel electrochromic materials, star-shaped oligothiophene derivatives with phenyl core, 1,3,5-tris (2′-thienyl) benzene (3TB) and 1,3,5-tris (5′-(2,2′- bithienyl)) benzene (3BTTB) were synthesized, and their electrochromic properties were investigated. It was found that 3TB and 3BTTB as solid films showed reversible, clear color changes on electrochemical doping and dedoping. The two oligothiophene derivatives with phenyl core constitute a new class of potential electrochromic materials.
