Abstract
Photogalvanic spectrometry is shown to be a very sensitive method for monitoring the initial steps of electrodeposition of conductive polyme rs on ITO surface. On the umnodified or mechanically scratched surface the first deposition step of poly(3-methylthiophene) is the precipita tion of highly conjugated polymer. If the ITO surface is modified by b onding bithienyl covalently, the polymerization seems to continue by e xtending the length of surface-bound oligomers.
