Novel porous aromatic framework with excellent separation capability of CO₂ in N₂ or CH₄

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.

Keywords
