Abstract

The effect of Br - anion on electrochemical behavior of (TPP)Co was investigated in 1,2 dichloroethane solution by microelectrode and thin layer cyclic voltammetry technique. It was found that the axially coordination of one Br - anion to (TPP)Co(Ⅲ)(Br -) 2 shifts the potential of porphyrin system to more positive value. The reduction peak of 0.12 V(vs.SCE) is attributed to the reduction of (TPP)Co(Ⅲ)(Br -). It is also postulated that the reduction of (TPP)Co(Ⅲ)(Br -) 2 occurred at a more negative potential where the reduction of the Co(Ⅱ)/Co(Ⅰ) process happened.
