Absolute asymmetric electrochemical polymerization

摘要

Electrochemical polymerization of thiophene-based achiral monomer having azobenzene as a chromophore irradiated by circular polarized light (CPL) was carried out to obtain chiroptically active polymer film on indium-tin oxide-coated glass. Circular dichroism and optical absorption spectroscopy measurements indicate the samples show chiroptical activity. This result indicates occurrence of absolute asymmetric polymerization by laser CPL.
