| Abstract: 5-(4-acetamidophenyl)-10,15,20-tris(4-mthylphenyl) porphinatozinc (Ⅱ) was synthesized. The electric absorption spectra of axial coordination reaction of symmetrical and unsymmetrical Zn(p-X)TPP with imedaxole series were investigated. The influence on a red shift of entire spectra and a decrease in Aβ/Aα was discussed. Coordination number and equilibrium constants of axial coordination reaction were measured by visible spectra techniques and the method of Rose-Drage. The changes of standard molar enthapy ΔrHmO and standard molar ΔrSmO of reactions were obtained from the plots of lnKO vs 1/T. It was found that logKeqO for imedazole series addition varies linearly with the sum of the Hammett sigma constants for all complexes investigated. |
