A series of phenylene-based conjugated microporous polymers (CMPs) of the A(6) + M-x (x = 2, 3, 4, 6) type were synthesized. By tuning the monomer length and geometry, the BET surface area of CMPs can be tuned from 571 to 1115 m(2) g(-1). Amongst the synthesized CMPs, A(6)CMP-1 exhibits the highest CO2 adsorption capacity of 1218 mg g(-1) at 318 K and 60 bar pressure. In addition, A(6)CMP-4 shows a high selectivity ratio of 47 for CO2/N-2.
