• polymers (HCPs), a series of 9-phenylcarbazole (9-PCz) HCPs (P1–P11) has been made by changing the molar ratio of cross-linker to monomer, the reaction temperature T1, the used amount of catalyst and the concentration of reactants. Fourier transform infrared spectroscopy was utilized to characterize the

The BET specific surface area of the prepared HCPs was up to 769 m2 g−1, and the CO2 uptake capacity was up to 10.4 wt % at 273 K/1 bar. Experimental Materials 9-Phenylcarbazole, FDA and DCE were purchased
