Porous Cationic Covalent Triazine-Based Frameworks as Platforms for Efficient CO2 and Iodine Capture.

Porous cationic covalent triazine-based frameworks (CTFs) with imidazolium salts as tectons were prepared via ionothermal synthesis. The high-PF6 - -content CTF shows the CO2 adsorption of 44.7 cm3 g-1 and I2 capture capacity of 312 wt %. The influence of counterion species and contents on the porosities, CO2 adsorptions, and I2 capture capacities of the CTFs has been investigated.
