Characterization of the first steps in electropolymerization by photocurrent spectroscopy
Abstract
By using photocurrent spectroscopy it is shown that the first traces of poly(3-methylthiophene) electropolymerized onto bare indium tin oxide (ITO) already have a long conjugation length, whereas electropolymerization onto ITO with immobilized bithiophene or bare platinum results in a stepwise chain growth of the surface-confined polymer.
