【Abstract】 Objective: To investigate the effect of pH on the electrochemistrical properties of poly-copper tetraaminophthalocyanine (P-Cu TAPc)film. Method: The p-CuTAPc film was prepared by anodic electroploymerization on glass carbon electrode. The electrochemistry property of the p-CuTAPc film in B-R buffer solution was studied by using CV. Result: The electrochemistry property of the p-CuTAPc film was related to the solution acidity . The redox potentials were found to be pH dependent with a slope of -61 mv/pH. Conclusion: Both H + and OH - participate in the redox reaction of the p-CuTAPc film.更多还原
