Özet
In the present study, the electrosynthesis and the electrochemical characterization of azo dyes doped poly(3,4-ethylenedioxythiophene (PEDOT) were described. PEDOT film was electrochemically deposited onto indium doped tin oxide (ITO) coated/glass electrode, following azo dyes adsorption. The electropolymerized-PEDOT films on ITO glass were doped with carious azo dyes; 4-Phenylazo-2-phenyliminomethyl-phenol (PAPM), 4-Phenylazo-2-(p-tolyimino-methyl)-phenol (PATM) and 4-[(2-Hydroxy-5-phenylazo-benzylidene)-amino]-benzenesulfonicacid (HPAB). The structures of azo dyes-doped PEDOT ere characterized via cycle voltammograms and electrochemical impedance spectroscopy (EIS). Diverse doping counterions have a significant influence on the electrochemical behaviour of electropolymerized-PEDOT film. The electropolymerized-PEDOT doped by HPAB (PEDOT-HPAB) film possesses higher electrochemical activity than other azo dye-doped PEDOT composites. The main characteristics of PEDOT-azo dyes films contain uniformity, durability, and adherent on ITO electrodes. which are better when it is compared to PEDOT film.
