Abstract

In this study, electrochemical behaviors of formazans were investigated. The compounds contained CH_3 and OCH_3 groups at the o-, m-, and p-positions of the 1-phenyl ring and an OCH_3 group at the p-position of the 3-phenyl ring. Their electrochemical behaviors, such as the number of electrons transferred, diffusion coefficients, and heterogeneous rate constants, were studied by cyclic voltammetry, ultramicrodisk electrode, and chronoamperometry. Possible mechanisms were proposed based upon the data obtained. There was a correlation between the absorption and electrochemical properties. A linear correlation was obtained between \lambda_{\max} and E_{red2} and Hammett substituent coefficients with E_{red2} and k_s values.
