中文摘要
由金属离子和有机配体构成的配位聚合物正在成为一类被广泛重视的新型微孔材料，具有潜在的储氢及气体吸附功能。我们选择了刚柔性不同的多官能团有机磺酸、羧酸及联吡啶为配体，与不同主族金属离子、过渡金属离子及稀土离子相互作用，通过配体与金属离子的自组装，合成了多个配位聚合物，通过元素分析、红外光谱、X射线粉末衍射、热重分析等方法对它们进行了表征，并测定了部分配合物的单晶结构。另外，还初步研究了对氨基苯磺酸铜对氨及胺类小分子的吸附作用。
英文摘要
Coordination polymers built by metal ions and organic ligands are highlighted as a new type of microporus materials, which have potential function of hydrogen storage and gas adsorption. We employed multi-group organosulfonic acids of different flexibility, carboxylic acid and bi-pyridine as the ligands to construct coordination polymers. Several single crystals were obtained by the reaction of ligands with main group metal, transition metal and rare earth cations. Elemental analysis, Fourier transform infrared spectroscopy (FTIR) including variable-temperature FTIR, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA) were presented to extensively study the structures of these coordination polymes. The adsorption of ammonia and some amines on (p-C6H6NSO3)2Cu(H2O)4 were investigated, and the corresponding adducts were characterized by elemental analysis, FTIR, PXRD and TGA.
