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 (Qst) (37.8 kJ mol-1 at 273 K) and reasonable CO2 adsorption (7.8 wt% at 273 K/1 bar) as well as good selectivities, CO2/N2 (51) and CO 2/CH4 (6.3). The Brunauer-Emmett-Teller (BET) surface area of IBTP was 328 m2 g-1 and it also showed good thermal stability up to 450 °C under a N2 atmosphere, thus showing good potential for CO2 capture.
