Liquid phase epitaxial layer by layer dipping assembly of metal-organic framework thin films and their physical property

金属-有机框架(MOF)作为一种通过配位键将金属节点和有机配体连接而成的新型无机-有机杂化多孔有序晶体材料,因其具有比表面积大、稳定性好、结构多样以及功能可调等优点,受到人们的广泛关注.MOF薄膜的制备和功能化拓展了其应用领域.本文重点介绍了用液相外延层层浸渍法组装表面配位金属-有机框架薄膜(SURMOF),并总结了部分SURMOF在光学、电学等方面的物理性能,以及对SURMOF的应用前景进行了展望.

Metal-organic framework(MOF)is a new kind of inorganic-organic hybrid porous ordered crystal material,which is connected by metal nodes and organic ligands through coordination bond.Because of its large specific surface area,high stability,diverse structure and adjustable function,MOF has received wide attention.The improvements in preparation and functionalization of MOF thin films expand their application fields.In this paper,the method for assembly of surface coordinated metal-organic framework thin films(SURMOF)by liquid phase expitaxial layer-by-layer dipping method is introduced,and the physical properties of some SURMOFs in optics,electricity and other aspects are summarized,and the application prospect of SURMOF is prospected as well.
