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 (691 m 2 g -1 ) and high physicochemical stability. By utilizing the bottom-up strategy, the surfaces of the pore walls were covered with the N-H sites, together with their microporous structures, lead to the high carbon dioxide (CO 2 ) adsorption capability (10.5 wt% at 273 K and 1.0 bar) and heat of adsorption (34.6 kJ mol -1 ).
