Abstract: The axial coordination effect of F- on the redox behavior of (TPP)Co was investigated by F- titration with cyclic voltammetry detection and spectroeletrochemistry in dichloroethane.It was verified that mono(F-) axial adduct (TPP)Co(N) (F-) could be reduced at O.1 V(SCE), and bis(F-) axial adduct (TPP)Co(Ⅲ) (F-)2 formed with added Fmolar ratio>1 could be reduced at the potential <-0.6 V(SCE).The equilibrium between (TPP)Co(Ⅲ) (F-) and (TPP)Co (Ⅲ) (F-)2 was demonstrated.
