A thermodynamic study has been carried out for the axialcoo rdina tion reactions betw een chiral po rphy rin and some imida zo le-like lig ands. Elect ronicimplica tion is found to be an impo rtant factor in i ts thermodynamics, furthermore, wi thmolecular mechanics method, MM 2, and semi-empirical method in Quantum Chemist ry ,AM1, configura tion optimiza tion and o ther calculation have been ca rried out on porphyrins andlig ands, who se resul ts are inline w ith the experiments.Key words: chira l metallopo rphy rin; axial coo rdination; thermodynamics; AM 1; MM2·6· 　? ? ? ? ? ?
