离子热合成金属-有机骨架材料最新研究进展

摘要

Ionothermal synthesis is a new method for the preparation of metal-organic framework materials with novel topologies in past decades. The recent developments in the ionothermal synthesis of metal-organic frameworks are reviewed. Various methods of ionothermal synthesis were introduced and the influences of ionic liquid on frame structure,as well as the synthesis of chiral metal-organic frameworks under ionothermal condition,were discussed in detail. Moreover,the advantages and shortcomings of ionothermal synthesis were analyzed and compared with traditional hydrothermal/solvothermal synthesis , especially the structural differences of several classical metal-organic frameworks obtained from hydrothermal/solvothermal or ionothermal methods were compared. It was pointed out that the mechanism of the ionic liquids influencing the structures of the metal-organic frameworks needs further investigation.%离子热合成是近年来新兴的合成具有新颖拓扑结构的金属-有机骨架材料的方法。本文综述了离子热合成金属-有机骨架材料的研究进展，介绍了离子热合成金属-有机骨架的具体合成方法，重点探讨了离子液体的阴阳离子对骨架结构的影响及离子液体在手性金属-有机骨架材料合成方面的研究情况。另外，还将离子热合成方法与传统水热/溶剂热合成方法进行了详细地比较，并针对几种代表性的金属-有机骨架材料的合成，探讨了不同合成方法得到的材料在结构上的差异。离子液体的种类和结构对金属-有机骨架材料结构方面的影响机理还有待于进一步的探讨。
