摘要：

The electropolymerization of o-anisidine leads to the formation of a polymer which is in the same time strongly oxidized and charged in a large potential range: the poly-o-methoxyaniline (POMA). The POMA Raman features are strongly different from the polyaniline (PANI) ones; in particular a new band, absent from the PANI spectrum, prevails in a large potential range. The nature of the polymer structures obtained in function of the polarization potential is discussed from their Raman spectra. A new polymeric configuration of the oxidized/charged rings is therefore described. (c) 2007 Elsevier Ltd. All rights reserved.
