Synthesis and electropolymerization of terthienyl carrying a photochromic group
Abstract
A photochromic spironaphthoxazine group is covalently bonded to the 3′-position of terthienyl and the 3-position of thiophene; electropolymerization into spironaphthoxazine-functionalized polythiophene only occurs with the use of the spironaphthoxazine–terthiophene compound as the monomer.
