Abstract: Two kinds asymmetrical porphyrins and their zinc complexes were synthesized. The interaction of zinc complexes and amino acid esters was investigated. The stiochiometry of adducts of zinc complexes and amino acid esters is 1:1. 1H NMR studies reveal that the amino acid guest coordinates onto the center zinc atom of the porphyrin directly, α-proton of the amino acid ester is located in close contact with the porphyrin plane, while the methyl group is in a more off-centered location compared with the other groups.

Key words: asymmetrical metalloporphyrin, amino acid ester, binding constant
