Abstract: The title complex TNTBPCo(Ⅱ) was synthesized and characterized by elemental analysis, UV-vis, spectrum, IR photoacoustic spectrum, H NMR and molar conductance measurements. Its electrochemical behavior has been investigated by cyclic voltammetry in DMSO. The half wave potential of [TNTBPCo(Ⅲ)]+/TNTBPCo(Ⅱ) was -0.255 V and that of TNTBPCo(Ⅱ)/[TNTBPCo(Ⅰ)]-1 was -1.175 V. The half wave potential of redox of porphyrin ring [TNTBPCo(Ⅰ)]-1/[TNTBPCo(Ⅰ)]-2 was -1.850 V.

Key words: tetranaphthyl tetrabenzoporphyrin, colbalt complex, synthesis, characterization, electrochemical behavior
