Abstract:

A homochiral MOF {[Co(L-trp)(bpe)(H2O)]·H2O·NO3}n[L-trp=L-tryptophan, bpe=1,2-bis(4-pyridyl)ethylene] with 2D chiral layers was synthesized and used as a new chiral stationary phase for high-performance liquid chromatographic enantioseparation in this study. The chiral MOFs was characterized by powder X-ray diffraction(XRD) and scanning electron microscope(SEM). The experimental results showed that 3 isomers and 11 recemates were separated on {[Co(L-trp)(bpe)(H2O)]·H2O·NO3}n packed column. The chiral column also exhibited good reproducibility and stability.

Key words: Metal-organic framework, High-performance liquid chromatography, Chiral enantioseparation
