摘　　要：The electric absorption spectra of axial coordination reactions of tailed phenylalanine tetraphenylporphyrinato cobalt(Ⅱ) Co[Phe-TPP]with imidazole(Im),2 Methyl imidazole(2 MeIm) and N Methylimidazole(N MeIm) have been studied.The standard equilibrium constant K and stoichiometric number n of reaction were measured by visible spectroscopy.The changes of standard molar enthalpy Δ rH  m and standard molar entropy Δ rS  m of the reaction were obtained from the plots of lnK υs 1/T.The electric absorption spectra of axial coordination reactions of tailed phenylalanine tetraphenylporphyrinato cobalt(Ⅱ) Co[Phe-TPP]with imidazole(Im),2 Methyl imidazole(2 MeIm) and N Methylimidazole(N MeIm) have been studied.The standard equilibrium constant K and stoichiometric number n of reaction were measured by visible spectroscopy.The changes of standard molar enthalpy Δ rH  m and standard molar entropy Δ rS  m of the reaction were obtained from the plots of lnK υs 1/T.
