Targeted synthesis of novel porous aromatic frameworks with selective separation of CO2/CH4 and CO2/N2

Novel porous aromatic frameworks (PAF-53 and PAF-54) have been obtained by the polymerization of amino compound (p-phenylenediamine and melamine) and cyanuric chloride. They display a certain amount of CO2 adsorption capacity and highly selective separation of CO2/CH4 and CO2/N2 as 18.1 and 83 by Henry Law respectively. They may be applied as ideal adsorbents to separate and capture CO2.
