In this study, (S)-SEGPHOS was adopted as chiral extractant to recognize amino acid enantiomers. Phenylalanine (Pha), homophenylalanine (Hpha), 4-nitro-phenylalanine (Npha), phenylglycine (Phg), 3-chloro-phenylglycine (Cphg), and tyrosine (Tys) were selected as substrates to estimate the enantioselectivities of (S)-SEGPHOS-metal complexes. (S)-SEGPHOS-Pd was an excellent chiral extractant to recognize Npha with operational enantioselectivity (α) was 4.25. And (S)-SEGPHOS-Cu was a good chiral extractant to recognize Pha, Hpha, Phg, Tys, and Cphg withαwere 2.87, 1.93, 2.28, 4.07, and 2.94, respectively. After optimization by response surface methodology, the highest performance factors (pf) for Pha, Hpha, Phg, Npha, Tys, and Cphg were 0.22893, 0.11085, 0.14003, 0.25476, 0.21414, and 0.23142, respectively. Based on experimental results, the possible recognize mechanisms were discussed.
