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阳离子的多孔配位聚合物(PCP),并进行了结构表征。具有尺寸为 4.9 × 4.9 Å2 的一维通道的多孔框架表现出高热稳定性(∼330 °C),为 CO2、丙酮和苯提供 I 型吸附等温线。 13C NMR 的化学位移和吸附在该化合物中的丙酮的特征吸附能(βE0)代表了该骨架的路易斯酸度。
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.
