The electrochemical behavior of 5-(4-Dimethylamino-benylidene)-1,3-diethyl-2-thioxo-dihydro-pyrimidine-4,6-dione at a plat-inum electrode was studied by semi-integration, semi differentiation of current, and digital simulation methods in 0.1 mol/L tetra-ethylammonium perchlorate (TEACl) in acetonitrile solvent. Cyclic voltammetric study revealed that the presence of three oxidative peaks due to the presence of two electron transfer coupled by chemical reaction (EC) and followed by electron transfer (E) step then EC, i.e., the overall process is ECEEC scheme. On going to negative potential there are two unidirectional reductive peaks associated with the oxida-tive peaks. The elucidation of the electrode behavior, the electrochemical and chemical data of the compound under investigation was de-termined using sweep voltammetry, semi integration & semi differentiation of current. The calculated electrochemical parameters and the nature of the electrode reaction were established & confirmed via generation of the theoretical cyclic voltammograms.

Three carbazole chromophores derivatives featuring dicyno, cyano, ethyl acetate and dimethyl acetate groups as an acceptor moiety with a ? – conjugated spacer and N-methyl dibenzo[b]pyrole as donor were investigated electrochemically at a platinum electrode in 0.1 mol/L tetraethylammonium chloride (TEACl) in acetonitrile solvent via cyclic voltammetry, convolution – deconvolution transforms and digital simulation techniques. Cyclic voltammetric study revealed that the presence of a single reversible oxidative peak due to two sequential electron transfer (EE scheme) and unidirectional reductive peak which proceed as ECEC mechanism. The electrode reaction pathway, the relevant chemical and electrochemical parameters of the investigated carbazole chromophores were determined using cyclic voltammetry, convolution- deconvolution transforms and chronoamperograms. The extracted electrochemical parameters and the nature of the electrode reaction were verified & confirmed via digital simulation method.

The present work aims to report the investigation of the electrochemical behavior of 3- arylazomethine-1,2,4-triazole derivatives in universal aqueous buffer series at mercury electrode. The electrode behavior of the studied compounds was performed via voltammetric studies, chronoamperometry, convoluted transforms, and dp polarography techniques. The relevant chemical and electrochemical parameters of 3- aryl azomethine -1,2,4- triazole derivatives were determined experimentally in universal aqueous buffer series as supporting electrolyte at mercury electrode. CPC was used for determination of the number of electrons to elucidate the mechanistic pathway of electrode reaction of aryl azomethine triazole compounds. Digital simulation method was used to confirm the accuracy of the experimental chemical parameters (homogeneous chemical rate constant) and electrochemical parameters (heterogeneous rate constant, symmetry coefficient and redox potential) via matching between the experimental and theoretical cyclic voltammograms.
