| titleOfInvention | Hydrazone bond connection type chiral covalent organic framework bonded silica gel stationary phase and application thereof |
| abstract | The invention relates to a hydrazone bond connection type chiral covalent organic framework bonded silica gel stationary phase and application thereof. The stationary phase is prepared by the following method: under inert atmosphere, uniformly mixing a hydrazide chiral precursor, trimesic aldehyde and ammoniated silica gel in an organic solvent, then reacting under the catalysis of acetic acid, filtering, washing and drying to obtain the chiral covalent organic framework bonded silica gel stationary phase, wherein the structure of the hydrazide chiral precursor is as shown in formula (I) The mass ratio of the ammoniated silica gel to the hydrazide chiral precursor is 2-12: 1, and the molar ratio of the hydrazide chiral precursor to the trimesic aldehyde is 1: 0.5-2. The chiral covalent organic framework bonded silica gel stationary phase provided by the invention has uniform particle size; the chiral covalent organic framework bonded silica gel stationary phase has the advantages of high column efficiency, moderate column pressure and good separation effect on cis-trans isomers and position isomers when being applied to high performance liquid chromatography, and meanwhile, the chiral covalent organic framework bonded silica gel stationary phase has a definite structure, a simple preparation method and good batch reproducibility. |
