Started off with the normal chiral material, L (+) tartaric acid, a series of novel chiral Zinc(Ⅱ) porphyrin is prepared, and Elements analysis, NMR, Uv vis and Polarization analysis give the characterization. A thermodynamic study has been carried out for the axial coordination reactions between chiral porphyrin and some imidazole like ligands. Electronic implication is found to be an important factor in its thermodynamics, furthermore, with molecular mechanics method, MM2, and semi empirical method in Quantum Chemistry, AM1, configuration optimization and other calculation have been carried out on porphyrins and ligands, whose results are inline with the experiments.
