金属-有机骨架材料用于色谱固定相

Metal-Organic Frameworks Used as Chromatographic Stationary Phases

金属-有机骨架材料(metal-organic frameworks,MOFs)是一类新型多功能材料,具有迷人的结构和不同寻常的特性,如多孔性、高比表面积及良好的化学和热稳定性。MOFs在近十来年的时间里已经引起了人们的广泛关注。与传统的无机多孔材料相比,其最重要的特点在于MOFs的结构具有可设计性,可以灵活选择适宜的金属离子或簇以及具有特定官能团和形状的有机配体合成出具有特定功能、孔穴尺寸可控的MOFs。目前,已有大量的MOFs被合成出来,并在许多领域显示出了良好的应用前景,如气体储存、催化和分离方面。本文综述了近年来MOFs用于色谱固定相的研究进展,详细介绍了MOFs在液相色谱(LC)和气相色谱(GC)中的应用。最后,对这种新型多功能材料在色谱方面的应用进行了前景展望。

Metal-organic frameworks （MOFs） is relatively a new class of muhi-functional materials with fascinating structures and unusual properties, such as porosity, high surface areas, as well as excellent chemical and thermal stability. MOFs have attracted a great deal of attention in the past decade. Comparing with conventional inorganic porous materials, an important feature of MOFs is that their framework structures can be finely controlled. Therefore, MOFs with specific function and adjustable pore size can be synthesized by the choice of metal ions or clusters and organic building blocks with specific functional groups and shape. Recently, a large number of MOFs have been synthesized and shown potential applications in many areas, such as gas storage, catalysis and separation. This review summarizes the research progress on application of MOFs as stationary phases in liquid chromatography and gas chromatography. Finally, a prospect of the application of this new class of multi- functional materials in chromatography is given.
