摘要：

The electrooxidation of o-methoxyaniline (o-MA) has been studied by electrochemical and surface-enhanced Raman scattering (SERS) methods. The electrochemical measurements showed that the early stages of o-MA electropolymerization were affected by both the monomer to acid concentration ratio and by the acid concentration. The SERS experiments demonstrated the C-N coupling mechanism of o-MA dimerization or oligomerization. The results of both methods indicate that the intermediate redox couple observed in electrochemical response of poly( o-methoxyaniline) can be assigned to the incorporated dimer probably having the cyclic structure.
