微孔镧系配位聚合物

微孔配位聚合物与通常的微孔无机材料相比, 具有非常明显的优势. 而镧系离子特殊的光学和磁学性质, 更使得微孔镧系配位聚合物的研究成为热点. 本文简要地报道了微孔镧系配位聚合物的研究现状, 对一些微孔镧系配位聚合物的结构特点进行了描述, 讨论了影响微孔配位聚合物形成的主要因素. 一般来说, 线型配体往往能很好地将金属离子连接起来, 得到理想的微孔镧系配位聚合物; 选择合适的第二配体, 有利于构筑结构新颖的微孔镧系配位聚合物; 镧系收缩对能否形成微孔配位聚合物的影响并不明显, 只是轻稀土离子往往倾向于多结合一些小分子配体来满足更高的配位数.

Microporous Lanthanide Coordination Polymers

Microporous lanthanide coordination polymers are of great interest due to the obvious advantages as microporous materials and the special optical and magnetic properties of lanthanide ions. This paper presents a brief summary of microporous lanthanide coordination polymers. It seems that linear ligands and proper second ligands are effective to construct microporous lanthanide coordination polymers, while lanthanide contraction has no significant influence on the formation of microporous lanthanide coordination polymers. But in order to complete the high coordination numbers, light rare earth ions are liable to coordinate to more small ligands.
