Abstract: Molecular recognition of chiral zinc porphyrin [p-(L-Leu)C2O-TPPZn] with amino acid ester derivatives was investigated by UV-Vis spectrophotometric titration and CD spectroscopy. The experimental results suggested that the association constant was KD>KL for amino acid ester derivatives, and then increased following the order of K(AlaOCH3)

Key words: Chiral zinc porphyrin, Amino acid ester, Molecular recognition, CD spectroscopy, Simulated annealing
