Abstract
Thiophene adsorbed on a roughened gold electrode was studied in an aqu eous solution at various potentials from 0 to 1.0 V vs. SCE by use of surface enhanced Raman scattering. It was found that thiophene oligome rs and polythiophene were produced on the electrode surface at potenti al ranges of 0-0.6 V and 0.8-1.0 V, respectively. This potential range is significantly low compared to the potential used in the convention al electropolymerization of thiophene monomer (1.6 V vs. Ag/AgCl) in a cetonitrile medium).
