Diolefinic antibacterial laser dye namely 1,4-Bis[2-(4-Pyridyl) Vinyl] Benzene (4PVB)have been investigated electrochemically using cyclic voltammetry, chronoamperometry, convolution and deconvolution voltammetry combined with digital simulation techniques at a platinum electrode in 0.1 mol / L Tetra Butyl Ammonium Perchlorate (TBAP) in solvent 1,2-dichloroethane. The diolefinic species were reduced by consuming two sequential electrons to form radical anion and dianion. The second electron transfer was followed by chemical step i.e the electrode reaction proceed as EEC scheme. In scanning the potential to positive direction, the diolefinic laser dye compound was oxidized by loss of one electron, which was followed by a fast chemical process ( isomerization or association). The pathway of electrode reaction and the electrochemical parameters of the investigated compound were discussed & determined using cyclic voltammetry and chronoamperometry techniques. The extracted electrochemical parameters were verified and confirmed via digital simulation and convolutive voltammetry methods.
