  Abstract:  The electrochemical behavior of a new charge transfer complex between 7,7,8,8-tetracyanoquinodimethane and 16H,18H-dibenzo[c,1]-7,9-dithia-16,18-diaza-pentacene adsorbed on spectrographic graphite has been investigated. Cyclic voltammetry measurements, performed in aqueous buffer solutions at different potential scan rates and pH values, pointed out to a quasi-reversible, surface confined redox process. The voltammetric response involves the transfer of 1e-/1H+, with a heterogeneous rate constant of 26.8 s-1 (pH 7.0). The modified electrodes showed a good electrochemical stability as well as moderate electrocatalytic activity toward NADH electro–oxidation.
