| Abstract: | The behavior of sanguinarine and chelerythrine alkaloids upon electrochemical oxidation on solid electrodes in buffered aqueous medium is reported in this study. Electro‐oxidation of sanguinarine and chelerythrine results in the formation of redox active electropolymerized films. The films were characterized by cyclic voltammetry, EQCM and surface enhanced Raman scattering spectroscopy excited in near‐infrared range. The electropolymerization is suggested to proceed via formation of alkaloids' ortho‐benzoquinone derivatives. |
