Design,Synthesis And Properties Of Functional Porous Organic Polymer Materials

Porous Organic Polymers?POPs?are mainly composed of light elements.Compared with Metal Organic Frameworks?MOFs?,silicon-based materials,carbon materials,etc.,POPs have a variety of preparation,structural design,The function can be adjusted through a strategy such as post-modification or a different synthesis.POPs materials have high specific surface area,low density,easy to functionalize and stable in nature,and are widely used in heterogeneous catalysis,gas adsorption separation,sensing and other aspects.Therefore,the design and synthesis of functional porous organic polymers are of great significance.?.COF-AO loaded with Pd NPs and PSI-SH were photopolymerized into a membrane by thiol-ene Click reaction.As a high-efficiency catalytic membrane microreactor,the dechlorination reaction of CBs in water was catalyzed at room temperature in a continuous flow operation.This study realizes the deviceization of COFs crystalline organic porous materials,and the complementary and functional integration of COFs and polymer materials,which has broad application prospects in the field of membrane reactor catalysis.?.The quaternization reaction of the diimidazole functional monomer with1,3,5-tris?bromomethyl?benzene in different solvents gives the imidazolium salt porous organic polymer POP-IL-DMF,which has strong CO₂ Adsorption capacity and selectivity,as a CO₂ stationary phase,can achieve cycloaddition of CO₂ and epoxide under relatively mild conditions,the material has both the catalytic properties of ionic liquids and the porous properties of POP,as a double Functional materials with broad application prospects.?.We designed and synthesized three different ionic COFs by post-modification and pre-synthesis methods respectively.COF-IL-3 was selected as the ideal carrier for the exchange of silicotungstic acid,and a good adsorption effect was obtained.Studies have shown that the functional organic groups can be introduced into POP bypre-or post-modification,and the synthesized functional organic porous polymers will exhibit excellent performance.This research expands the application scope of POP and lays a foundation for the practical application of POP.
