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 x 4.9 A2 shows high thermal stability ( approximately 330 degrees C), affording Type I adsorption isotherms for CO2, acetone, and benzene. The chemical shift of 13C NMR and characteristic adsorption energy (betaE0) of acetone adsorbed in this compound represent the Lewis acidity of this framework.
