Ae. Yassar et al., SYNTHESIS AND ELECTROPOLYMERIZATION OF TERTHIENYL CARRYING A PHOTOCHROMIC GROUP, Journal of the Chemical Society, Chemical Communications, (4), 1995, pp. 471-472
A photochromic spironaphthoxazine group is covalently bonded to the 3'
-position of terthienyl and the 3-position of thiophene; electropolyme
rization into spironaphthoxazine-functionalized polythiophene only occ
urs with the use of the spironaphthoxazine-terthiophene compound as th
e monomer.
