摘　　要：稀土有机框架材料（Ln-MOFs）因镧系离子存在特殊的电子排布[Xe]4fn （n =0～14）而具有独特的发光性和磁性，且具有不饱和配位的金属位和大的比表面积，在化学工业中具有广阔的应用前景而备受关注。研究表明，Ln-MOFs具有特殊的拓扑结构以及特定尺寸和形状的孔道，是一种新型多功能结晶材料，涉及了无机化学、有机化学以及配位化学等多学科,然而，通过简单的设计直接合成得到精确的Ln-MOFs是比较困难的，且有机配体和镧系金属单元具有无穷组合，故Ln-MOFs的合成与应用依然是今后研究的重点。文中以设计合成稀土有机框架材料（Ln-MOFs）的配体类型为主线，综述了Ln-MOFs的合成与结构，重点阐述了其在催化剂、热稳定性、气体吸附、发光材料、磁性材料等方面的应用。The chemical industry has attached increasing attention to the lanthanide-based metal-organic Framework （Ln-MOFs） material due to its unique luminescent and magnetic properties that are derived from the electronic configurations [Xe]4fn （n=0-14） of lanthanide elements and unsaturated-coordinated metal site and large specific surface area. The researches show that Ln-MOFs is a new multifunction crystal material with special topological structure and pore canal, which is closely related to inorganic chemistry, organic chemistry and coordination chemistry and other disciplines. However, it is difficult to obtained precise Ln-MOFs by sim-ple synthesis and design. Due to its infinite combination for the organic ligands and lanthanide metal unit, the synthesis and application of Ln-MOFs are still the future research focus. The synthesis and structure of Ln-MOFs are reviewed, in particular, its utilization in the fields of catalysts, thermal stability, gas adsorption, lu-minescent materials and magnetic materials on the basis of the analysis of Ln-MOFs type ligands.
