摘要:

金属-有机骨架(metal-organic frameworks, MOFs)材料是一种由金属离子和有机配体通过自组装形成的新型多孔材料,具有优异的物理及化学性能,因而在气体吸附储存、气体分离以及工业催化等方面表现出良好的应用潜力。但在应用的过程中,无处不在的水分子会影响MOFs骨架的稳定性和吸附性能,极大地制约了其实际应用。本文介绍了近年来疏水性MOFs材料的研究进展,重点论述了金属离子和有机配体对调控MOFs亲疏水性的影响以及通过配体后修饰和疏水性物质复合等提高疏水性的方法,分析了MOFs材料的亲疏水性机理,同时提出了实验结合计算机模拟技术筛选疏水性MOFs的手段。最后,指出目前疏水性MOFs材料合成存在的问题及解决方法,期望为今后拓宽MOFs材料在高湿环境中的应用提供一些有用的参考。

Abstract:

Metal-organic frameworks (MOFs), a new type of porous material self-assembled by metal ions and organic ligands, exhibit excellent physical and chemical properties. Thus, it makes them promising candidates in gas adsorption, storage, gas separation and industrial catalysis and so on. But in the process of application, the water molecules will affect the stability and adsorption performance of MOFs, which greatly restricts its practical application. In this paper, the research progress of hydrophobic MOFs materials in recent years is introduced. The effects of metal ions and organic ligands on the regulation of hydrophilicity, and the ways of improvement of hydrophobicity by post-modification of ligands and compounding of hydrophobic materials are discussed. The hydrophobic and hydrophobic mechanism of MOFs are analyzed. Moreover, the method of screening hydrophobic MOFs by experiment and computer simulation are given. In the end, the existing problems in the synthesis of hydrophobic MOFs and their solutions are pointed out. It is expected to provide some useful potential application of MOFs materials in high humidity environment.

Key words: MOFs, hydrophobic, metal ions, organic ligands, compound material
