SERS OF 1,8-DIAMINONAPHTHALENE ON GOLD, SILVER AND COPPER ELECTRODES - POLYMERIZATION AND COMPLEXES FORMED WITH THE ELECTRODE MATERIAL

Oxidation of 1,8-diaminonaphthalene (1,8DAN) on gold, silver and coppe r electrodes has been studied by SERS spectra. SERS results have been compared with Raman spectra of poly-1,8DAN thin films deposited on the platinum support. Oxidation of I,8DAN on gold and silver electrodes l eads to polymerisation. The pretreatment of the silver electrode influ ences the polymerisation: exposing the silver electrode to day light d uring the ORC procedure encourages growth of the polymer layer. In the case of a copper electrode the Cu2(+)-(1,8DAN)(n) complex is formed. (C) 1997 Elsevier Science S.A.
