Problems solved by technology

[0004] However, some shortcomings of MOFs materials lead to limitations in its application: (1) After the MOFs lose solvent molecules, their structure becomes unstable, and the structure containing the porous skeleton is easy to collapse, resulting in shrinkage of pore size or formation of amorphous amorphous Pore ​​structure; (2) Sensitive to the environment: Most of MOFs materials are extremely sensitive to water molecules in the gas, and contacting for a long time may lead to structural changes or

Abstract

The invention provides a porous pyrenyl organic framework material rich in hydroxyl and a preparation method thereof. The method comprises the following steps of under inert atmosphere, performing condensation polymerization on a phenol compound and tetra-formyl group aromatic aldehyde in an organic solvent to obtain the porous pyrenyl organic framework material rich in the hydroxyl, wherein the phenol compound is polybasic phenol or polybasic naphthol; the tetra-formyl group aromatic aldehyde contains 4 to 8 benzene rings, and four formyl groups are respectively connected with four different benzene rings; and the organic solvent is an alcohol organic solvent or an ether organic solvent. The porous pyrenyl organic framework material rich in the hydroxyl, provided by the invention, is a formless macromolecule net working polymer obtained by leading the phenolic group ortho-position or para-position of the phenol compound and the formyl groups in the tetra-formyl group aromatic aldehyde to generate condensation polymerization, and has fluorescence.

Description

technical field [0001] The invention relates to the technical field of organic materials, in particular to a hydroxyl-rich porous pyrenyl organic framework material and a preparation method thereof. Background technique [0002] Porous framework materials have an interconnected network porous structure, so they have the advantages of larger specific surface area and lower density than other materials, and are widely used in heterogeneous catalysis, hydrogen storage, adsorption, ion exchange, gas separation and other fields. As porous framework materials have attracted more and more attention, their high-quality material properties have attracted more people to explore. [0003] Porous framework materials include metal-organic frameworks (MOFs) and covalent organic frameworks (COFs). Metal-organic frameworks (MOFs), also known as hybrid compounds or coordination polymers, are self-assembled with a supramolecular microporous network structure formed by the metal-coordination ...
