Document Type and Number:
WIPO Patent Application WO/2022/247674
Kind Code:
A1
Abstract:
The present application relates to a three-dimension carboxylic acid covalent organic framework, a preparation method therefor and the use thereof. The three-dimension carboxylic acid covalent organic framework is prepared from a monomer and a compound by means of the linkage of an imine bond formed by reacting a formyl group of the monomer with an amino group of the compound. The structural formula of the monomer is formula (I), formula (II) or formula (III), wherein R1 is C, Si, or a substituted or unsubstituted biphenyl, and R2-R31 are respectively independently selected from H, a C1-C6 linear alkyl, a C1-C6 branched alkyl, or a C1-C6 alkoxy; or is formula (VI), * being a linkage site. The structural formula of the compound is (IV) or (V), and R32-R43 are respectively independently selected from H, Cl, Br, F, I, nitro, hydroxyl, a C1-C6 linear alkyl, a C1-C6 branched alkyl, or a C1-C6 alkoxy, and at least one of R34-R41 is carboxyl.
