The mechanistic studies of the electrochemical in situ association of sopper ions with 5,10,15,20-tetraphenyl-21H,23H-porphyrin

摘要

A trace of 5,10,15,20-tetraphenyl-21H,23H-porphyrin (H_2TPP) was mechanically transferred to the surface of a paraffin-impregnated graphite electrode and sassociated with copper ions in an aqueous media by electrochemistry.Under different electrochemical conditions,two cases of surface associations of H_2TPP with copper ions are obtained.The formations were characterized by the voltammetry of the immobilized microparticles.According to the different voltammetric behaviors of the two cases of the in situ formed copper porphyrins,the different association mechanisms of the two cases of copper porphyrins were elucidated.
