preparation example Construction

[0025] The preparation method of the above-mentioned cross-linked polymer based on copolymerized fluorenyl alcohol is as follows: using the fluorenyl tertiary alcohol copolymer as a reaction substrate, Friedel-Crafts reaction occurs in the presence of an acid catalyst to form a corresponding fluorenyl cross-linked polymer, Its reaction route is:

[0026]

[0027] The specific steps are: add the fluorenyl tertiary alcohol copolymer as the reaction substrate into the reaction container, then add the solvent to dissolve it, finally add the acid catalyst, and react for at least 3 hours. After the reaction is completed, add water to quench the reaction. First extraction, drying over anhydrous sodium sulfate, and rotary evaporation under reduced pressure to remove the solvent until a viscous reaction solution remains, then settle with methanol, filter, and extract the filter residue with acetone in a Soxhlet extractor to finally obtain the target product .

Description

technical field [0001] The invention belongs to the technical field of organic semiconductor materials, and in particular relates to a cross-linked polymer material of copolymerized fluorenol and a preparation method thereof. Background technique [0002] Hypercrosslinked polymers (HCPs), a series of permanently microporous polymer materials originally reported by Davankov, are widely used in gas storage due to their advantages such as easy functionalization, high surface area, low-cost reagents, and mild operating conditions. Carbon capture, removal of pollutants, molecular separation, catalysis, drug delivery, sensing, etc., so it has been favored by scientists at home and abroad. In recent years, scientists have mainly prepared well-established polymer frameworks with tunable porous topologies by screening monomers, crosslinkers, and optimized reaction conditions. The methods involved mainly involve three types: 1. post-crosslinking 2. direct polycondensation or one-step...
