Synthesis of Urea-Based Functional Polymeric Materials and the Study of the Fixation Reaction of CO2
Organic functional polymeric materials have the advantages of high physical and chemical stability,easy functionalization,etc.,and have gradually become one of the most promising catalytic materials in the field of CO2 resource utilization.Herein,a series of urea-based organic functional polymeric materials have been designed and synthesized,characterized by FT-IR and SEM,and were applied to catalyze the cycloaddition of CO2 under solvent-free and mild conditions.Notably,the UCPs which were functionalized by crown ether group and urea group simultaneously showed excellent catalytic activity,while the UP functionalized by urea only demonstrated lower catalytic activity,this may be related to the synergistic catalytic effect of urea and crown ether active groups during the catalytic process.This study has certain reference value for the construction of functional polymeric materials.
