Abstract

The invention relates to a main chain azobenzene type organic porous polymer material and a preparation method thereof and belongs to the field of new materials. The structural formula of the organicporous polymer material is shown in the description. The method comprises the steps as follows: dispersing aryl diamine in a first solvent at ice-water bath temperature, adding an acid medium after uniform dispersion to enable aryl diamine to be completely dissolved; dropwise adding a nitrosation agent for a diazotization reaction to obtain diazonium salt; adjusting the Ph value of the diazonium salt solution to be neutral by an alkaline solution to obtain a neutral solution; dissolving aryl diphenol in a second solvent, then, dropwise adding the solution to the neutral solution for an azo coupling polymerization reaction, and performing treatment to obtain the organic porous polymer material. The preparation method has the characteristics that preparation is simple, raw materials are easyto obtain, the reaction condition is mild and the like. The obtained main chain azobenzene type organic porous polymer material has the characteristics of solubility, good thermal stability, high specific surface area, large pore volume and the like.

Description

technical field

[0001] The invention relates to a main chain azobenzene type organic porous polymer material (LAB-POPs) and a preparation method thereof, belonging to the field of new materials. Background technique

[0002] Intrinsically microporous polymers (PIMs) are linear organic porous polymer materials and are also rare solution-processable organic porous polymer materials. Due to the distorted conformation of the intrinsic microporous polymer molecular chains, the polymer chains cannot be closely packed in space to form intrinsic micropores [Chemical Society Reviews, 2006, 35(8):675]. Intrinsically microporous polymers have the advantages of large specific surface area, low density, and solution processing, and have great potential in the selective adsorption of organic solvents and greenhouse gases, and can also be used in hydrogen storage, catalysis, and other fields [Chemical Society Reviews, 2006, 35(8): 675; Advanced Materials, 2014, 26(21): 3526-3531; Chemical...
