| Abstract | A series of covalent triazine frameworks containing benzimidazole segments (CTF-BIs) were designed and prepared by dynamic trimerization under ionothermal conditions, based on the novel designed dicyano monomer of dicyano benzimidazole (DCBI). The CTF-BIs were all amorphous and exhibited BET surface areas up to 1549 m2 gā1. The effect of reaction conditions including the ratio of catalyst and temperature on the pore properties was discussed. Meanwhile, the CO2 adsorption capacity of all the CTF-BIs was studied and it was found that the CO2 uptake capacity was as high as 21.68 wt% at 273 K and 1.10 bar for CTF-BI-11. The CTF-BIs exhibited high selectivities for CO2 over N2 in the range of 31.3ā88.5 at 273 K, and 29.0ā102.7 at 303 K, respectively. |
