Abstract

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 (7.8 wt% at 273 K/1 bar) as well as good selectivities, CO₂/N₂ (51) and CO₂/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.
