摘　　要：镧系元素由于其优异的发光特性,如长寿命的激发态、尖锐的线状发射带和较大的Stokes位移等,在发光材料中表现出极大的优势,被越来越多地应用于高级功能发光材料的设计中.而环糊精作为第二代超分子主体分子具有易于功能化修饰以及特异性结合发光客体等优势而被广泛地用于构筑发光材料、荧光传感等超分子体系.作者从基于环糊精的镧系稀土配位化合物超分子组装体的构筑出发,对不同镧系环糊精发光材料的最新研究进展进行综述,为开发构筑新型多功能化镧系发光材料提供参考.最后,提出了稀土发光材料目前所遇到的科学问题,并对基于环糊精稀土发光材料的发展方向进行了展望.Lanthanide elements show great advantages in luminescence materials and are increasingly applied in the design of advanced functional luminescence materials due to their excellent luminescence characteristics,such as long-lived excited states,narrow emission bandwidths and large Stokes shift.Cyclodextrin,as the second generation supramolecular host molecule,is easy to be functionalized and specifically binds the luminescent guests,so it is widely used to construct supramolecular systems such as luminescent materials and fluorescence sensing probes.In this paper,based on the construction of supramolecular assemblies of lanthanide/cyclodextrin,the author reviews the recent research progress of different lanthanide/cyclodextrin luminescent materials,which will provide reference for the development of new multifunctional lanthanide luminescent materials.Finally,the scientific problems encountered by lanthanide luminescent materials are put forward,and the development direction of lanthanide/cylodextrin luminescent materials is prospected.
