A new class of chiral zinc () porphyrin complexes were synthesized by using L- (+) - tartaric acid as a chiral source. The products and their intermediates were characterized by means of elemental analysis, specific rotation and UV-vis spectra. The thermodynamic properties of the coordination reaction between these porphyrins and three kinds of imidazole ligands were studied. The electronic effects of substituents were found to strongly influence the thermodynamic properties of zinc porphyrins and ligands. The molecular mechanics and semi-empirical methods The structure of porphyrin and ligand was optimized and calculated, and the results consistent with the experimental phenomenon were obtained.
