摘　　要：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.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).
