摘要：

Raman spectroscopic (SERS) evidence is given for the formation of polypyrrole, oligomeric units of thiophene and, probably, polythiophene on a rough silver electrode. Electrochemical experiments indicated that they are promoted by an unreduced product of silver oxidation (a small amount of AgCl) remaining on the electrode surface after its roughening by an oxidation-reduction cycle. A mechanism for the oxidation of pyrrole and thiophene by photochemical reduction of AgCl is suggested. © 1990.
