Abstract

The invention discloses a chiral MOC liquid chromatography separation column for separating racemic compounds. Chiral metal-organic cages [Fe 4 L 6 ](ClO 4 ) 8 Solvent particles are used as the stationary phase of high performance liquid chromatography, chiral metal-organic cages [Fe 4 L 6 ](ClO 4 ) 8 Solvent crystals are composed of 1,4-bis(2-imidazole formaldehyde) butane, (R)-1-phenylethylamine and Fe(ClO 4 ) 2 ·6H 2 O is formed by molecular self-assembly. The chiral column showed good chiral recognition ability for seven racemic compounds. The invention realizes the use of chiral metal-organic cages (MOCs) as the stationary phase of liquid chromatography separation for the resolution of racemic compounds. The synthetic materials are cheap and easy to obtain, the column preparation cost is low, and the separation speed is fast and the stability is high. The good and reusable characteristics have opened up a new way for the application of porous materials in the field of separation science, and have a good application prospect in the field of chiral recognition.

Description

technical field [0001] The invention belongs to the technical field of liquid chromatography separation, and in particular relates to a chiral MOC liquid chromatography column prepared by using a novel metal-organic cage material with good chiral recognition performance as a stationary phase. Background technique [0002] Chirality is an essential property of nature and plays an important role in many fields such as pharmacology, agrochemistry, biology, and chemistry. The most important driving force for the study of chiral recognition comes from chiral drugs. In commonly used drugs, most of them exist as racemates. A series of actions of chiral drugs in vivo are closely related to their configurations, and there are significant differences in the biological activities and toxicity of enantiomers with different optical activities. Therefore, the separation and acquisition of single enantiomers of chiral drugs has become an urgent need of society. In view of the importance...
