Abstract
Provided are a covalent organic framework (COF), and a preparation method and use thereof. The preparation method includes: mixing 2,4,6-triformylphloroglucinol, a polynary aromatic amine, and a polar organic solvent, and subjecting a resulting mixture to a Schiff base reaction and precipitation in sequence to obtain a crude product, where a ratio of a volume of the polar organic solvent to a mass of the 2,4,6-triformylphloroglucinol is in a range of 300 mL:1 g to 500 mL:1 g; and subjecting the crude product to washing and drying in sequence to obtain the COF.
