A porous coordination polymer (PCP) with immobilization of sodium cations on the pore surface has been synthesized, by employing a bifunctional carboxylate/sulfonate ligand, and structurally characterized. The porous framework with 1D channels of the dimension of 4.9 × 4.9 Å2shows high thermal stability (∼330 °C), affording Type I adsorption isotherms for CO2, acetone, and benzene. The chemical shift of13C NMR and characteristic adsorption energy (βE0) of acetone adsorbed in this compound represent the Lewis acidity of this framework.
