Ionic hypercrosslinked polymers featuring hydrogen bonds and Lewis base sites for enhancing the CO <sub>2</sub> –epoxide coupling reaction
We introduce hydrogen bonding sites into ionic hypercrosslinked polymers and examine their role in promoting the CO<sub>2</sub>-epoxide coupling reaction. The amino-functionalized iHCPs-NH<sub>2</sub> exhibits the highest catalytic activity, achieving >99% cyclic carbonate yield without any solvent or co-catalyst. This performance stems from good CO<sub>2</sub> adsorption capacity, basic -NH<sub>2</sub> groups that activate CO<sub>2</sub>, and hydrogen bonding interactions between -NH<sub>2</sub> and epoxides.
