  摘要：

  Extra coordination of zinc complexes of bromo-substituted tetraphenylporphyrins was studied by spectrophotometry. It was found that the stability of complexes thus formed markedly increases upon beta-bromo-substitution in tetraphenylporphine. The effects of electronic and structural factors on the extra coordination were discussed. The stability constants of complexes formed by zinc porphyrins with organic bases were calculated, and the electronic absorption spectra of porphyrins in toluene and in other organic solvents were studied.

  Rate constants of zinc acetate complexation with 2,7,12,17-tetrabromo-5,10,15,20-tetraphenylporphine in toluene, pyridine, or acetic acid following the reaction H2TPP(beta-Br)(4) + Zn(Ac)(2) --> ZnTPP(beta-Br)(4) + 2HAc are determined at four temperatures in the interval of 298-328 K, and the activation energies and entropies are calculated. The effect of bromo-substitution in pyrrole fragments of a tetraphenylporphine molecule on the complexation kinetics and mechanism is discussed.
