Rezumat:

The formation of substituted poly-azo-azulene films was accomplished through electrochemical oxidation by scanning or controlled potential electrolysis. Conductive or isolating films have been obtained on glassy carbon, using acetonitrile as solvent and 0.1 M tetrabutyl ammonium perchlorate as supporting electrolyte, starting from differently substituted azoazulenes. The optimal conditions for the film formation (potential, charge, azoazulene structure) have been established.Their characterization was done by cycling voltammetry and redox probe voltammetry.
