【摘要】：金属有机框架物(MOFs)是近十多年发展起来的一类新型有机-无机杂化材料,由有机配体和无机金属单元构建而成,一般具有多变的拓扑结构以及独特的物理化学性质.MOFs具有特殊的孔洞框架结构,材料种类繁多,比表面积大,其孔穴的大小、形状及构成等可以通过选择不同配体和金属离子,或者改变合成策略加以调节.构成MOFs的配体可以是有机酸,也可以是有机碱,还可以是其他特殊的结构,除此之外在配体上也可以连接特殊官能团,制备具有特殊功能的MOFs材料.由于MOFs具有特殊而又多种多样的结构,因此在功能材料、气体吸附、药物缓释、催化及有机合成等方面有广泛的应用.本文以形成MOFs的金属为分类就近十年来各种MOFs的制备及其在催化有机反应中的应用进行了综述,并对其未来研究加以展望.
[Abstract]:Metal organic framework (MOFs) is developed in recent more than 10 years is a new kind of organic-inorganic hybrid materials by organic ligands and inorganic metal element construct, with changeful topology structure and unique physical and chemical properties of.MOFs with holes in framework of special structure, material variety, large surface area, the cavity size, shape and structure can choose different ligands and metal ions, or change the synthesis strategy to adjust. MOFs ligands can be organic acid, can also be organic alkali, can also be other special structure, in addition to the ligand can also be connected with special functional groups, preparation the special features of the MOFs materials. Because MOFs has special structure and varied, therefore has a wide application in functional materials, drug delivery, gas adsorption, catalysis and organic synthesis. This In recent ten years, the preparation of MOFs and its application in catalytic organic reactions were reviewed. The future research of MOFs was prospected.
