A new benzothiazole linked nanoporous polymer, imine benzothiazole polymer (IBTP), was synthesized via a Schiff base condensation reaction. IBTP showed high isosteric heat of adsorption (Q(st)) (37.8 kJ mol(-1) at 273 K) and reasonable CO2 adsorption (7.8wt% at 273 K/1 bar) as well as good selectivities, CO2/N-2 (51) and CO2/CH4 (6.3). The Brunauer-Emmett-Teller (BET) surface area of IBTP was 328 m(2) g(-1) and it also showed good thermal stability up to 450 degrees C under a N-2 atmosphere, thus showing good potential for CO2 capture.
