Cyclic voltammetry, convolutive voltammetry, chronopotentiometry and digital simulation studies of [Pt(C≡C tol)2(dppm)2Ir(CO)2]+PF 6 complex

The electrochemical behaviour of the heterobimetallic complex [Pt(C≡C tol)2(dppm)2-Ir(CO)2]+PF 6 was studied via cyclic voltammetry, convolutive voltammetry and chronopotentiometry at glassy carbon electrode in dichloromethane solution. The electrochemical parameters calculated from experimental data were tested and confirmed by matching the experimental cyclic voltammograms with the simulated data. It was found that convolutive voltammetry provided higher sensitivity, better resolution and more accurate method for determination of the electrochemical parameters than ordinary cyclic voltammetry.
