ABSTRACT: Electrochemical polymerization of an isothianaphthene based monomer for low-bandgap polymer was carried out in a polymer lyotropic liquid crystal. We prepared hydroxypropyl cellulose/N,N-dimethylformamide (HPC/DMF) lyotropic liquid crystal system as an electrolyte solution to perform electrochemical polymerization of a hydrophobic monomer, although water was commonly employed as a solvent for HPC. Resultant polymer prepared in HPC/DMF shows both electro-activity and optical activity. Fourier transform infrared absorption spectroscopy measurement reveals that the resultant material is composite of HPC and polyisothianaphthene based.
