Abstract
A novel β-ketoenamine-linked conjugated microporous polymer (KECMP-1) was synthesized via Schiff base condensation between 1,3,5-triformylphloroglucinol and m-phenylenediamine by conventional solvothermal synthesis without a template or a metal catalyst. KECMP-1 exhibits a considerable Brunauer–Emmett–Teller specific surface area (691m2g−1) and high physicochemical stability. By utilizing the bottom-up strategy, the surfaces of the pore walls were covered with the NH sites, together with their microporous structures, lead to the high carbon dioxide (CO2) adsorption capability (10.5wt% at 273K and 1.0bar) and heat of adsorption (34.6kJmol−1).
