Abstract

The invention discloses beta-ketone enamine chiral COFs (covalent organic frameworks) as well as a preparation method and an application of a bonded capillary gas chromatographic column prepared fromthe same. The beta-ketone enamine chiral COFs have advantages of high thermal stability, large specific surface area and uniform pore diameter distribution and can be applied to chiral recognition andseparation. The beta-ketone enamine chiral COFs and the bonded beta-ketone enamine chiral COFs capillary column prepared from the same can realize separation of mixed components of straight-chain paraffin and branched paraffin or mixed components of ethylbenzene and styrene and have good application prospects.

Description

technical field

[0001] The invention relates to the field of covalent organic framework functional materials, in particular to a preparation method of a β-ketoenamine chiral covalent organic framework material and a bonded capillary gas chromatographic column and its application in capillary gas chromatographic separation . Background technique

[0002] Covalent organic frameworks (COFs) are a new type of ordered porous crystalline materials, which are composed of small organic molecules containing light elements (C, H, N, O, B, etc.) linked by covalent bonds. . As one of the typical representatives of new porous materials, covalent organic framework materials have the advantages of light weight, low density, adjustable skeleton size, pore modification, highly ordered permanent porosity and large specific surface area, as well as thermal stability and chemical With good stability and other characteristics, it is widely used in gas storage, heterogeneous catalysis, proton c...
