The electrochemical behaviour of six novel conjugated polymers containing phenothiazine moieties in main chain was studied in DMF with 0.1M tetrabutyl ammoniumperchlorate (TBAP) bymeans of cyclic voltammetry (CV) on the glassy carbon electrode (GCE), as well as the electrochemical effect on Zn2+ and Hg2+ ions of the six polymers was investigated. The results show that these polymers all had well defined redox peaks, and the addition ofmetal ions had shifted the oxidation peak potential of the corresponding phenothiazine group to more cathodal position. By some electrochemical techniques, the electrode reaction processeswere investigated in detail and their dynamic parameters were obtained. In addition, the energy levels of the frontier orbits of the six polymers were calculated and analyzed using CV.
