新型多孔材料用作色谱手性固定相

It is well established that enantiomers often exhibit different biological and pharmacological responses. However, enantiomers remain a challenge to separate and analyze due to their identical physical and chemical properties in an achiral environment. Research on specialized separation techniques continues to be developed to obtain optically pure compounds. The separation of enantiomers by chromatographic methods, such as high-performance liquid chromatography (HPLC), gas chromatography (GC), and capillary electrochromatography (CEC), has become one of increasingly important research contents in chemistry over the past few decades due to the demand for pharmaceuticals, agrochemical, and food analysis. The chiral stationary phase (CSP) is key to separating and analyzing chiral compounds for these chromatographic resolution methods. With the rapid development of materials science, diverse types of porous materials as CSP have been studied in recent years. This review mainly focuses on investigating chiral porous materials as CSP for high-performance liquid chromatography (HPLC), gas chromatography (GC), and capillary electrochromatography (CEC) over the past five years. The chiral porous materials include chiral metal-organic frameworks (CMOFs), chiral covalent organic frameworks (CCOFs), chiral porous organic cages (CPOCs), chiral metal-organic cages (CMOCs), chiral microporous organic networks (MONs), and chiral mesoporous silicas (CMSs). Chiral recognition mechanisms of novel chiral porous materials are also discussed briefly. Finally, the related problems and prospects for CSP were briefly discussed.
