Abstract:

A novel porous aromatic framework, PAF-52, was obtained via the polymerization of tetrahedral monomer tetrakis(4-cyanodiphenyl) methane(TCDPM) with the aid of a facile ionothermal method. PAF-52 has a surface area of 1159 m2/g(BET), and shows a considerable high separation ability of CO2 in N2 or CH4 respectively at room temperature, using gas-chromatography experiments as evidence.

Key words: Porous aromatic framework, CO2 adsorption separation, Nitrogen-rich framework
