Electrochemical and surface spectroscopic methods for oxidation of glassy carbon and anodic formation of films from indole derivatives are used. The experiment was conducted by PARC Model 170 and 174 a electrochemistry instruments were used for voltammetry. A Leybold-Heraeus PHS-10 Electron Spectrometer was used for x-ray photoelectron Spectroscopy (XPS). Glassy Carbon (GC) surfaces were mechanically polished with 400 and 600 grit SiC, followed by 0.25 micron diamond paste. Finally polishing was with 0.3 micron alumina. Carbon paste and platinum surfaces were prepared by standard procedures. Ultra sonication was used to remove traces of polishing materials.
