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.
通过使用双功能羧酸盐/磺酸盐配体合成了一种在孔表面固定有钠离子的多孔配位聚合物（PCP），并对其进行了结构表征。具有尺寸为4.9×4.9 Ų的一维通道的多孔骨架显示出高热稳定性（约330℃），对二氧化碳、丙酮和苯呈现I型吸附等温线。该化合物中吸附的丙酮的¹³C NMR化学位移和特征吸附能（βE₀）代表了该骨架的路易斯酸度。
