Electrooxidation of O-Aminobenzylalcohol-Identification of Oligo-benzylether Structures and Polyaniline Type Polymer by IR and UV/VIS Spectra

摘要

The electrooxidation of O-aminobenzylalcohol was studied in aqueous acidic solutions.Two distinct electroactive and electrochromic products were identified by cyclic voltammetry,in situ UV/VIS and infrared spectra.In initial electrodeposition cycles the oligomers containing benzylether units are formed.Further oxidation-reduction cycles lead to the polyaniline-type polymer.Effects of the kind of acid present in the polymerization bath and of the acid concentration were also studied.
