The versatility and tailorability properties of coordination polymers make them widely concerned.The coordination polymer based on lanthanide showed special functional applications in magnetism,luminescent materials,sensing,electronic,and drug delivery.Design and synthesis of lanthanide complexs with various structure and excellent properties have become a hot spot on coordination chemistry.This article is focus on construct lanthanide complexs with excellent luminescent,magnetic and high stability properties,and the ligands of multi-carboxylic acid,sulfonic acid and terpyridine were used to prepare 20 complexes.We characterized them by single crystal X-ray diffraction,IR and so on.Their luminescent properties and magnetism were studied.This paper contains four chapters:Chapter 1:Summarized the prospect of application and research status of coordination polymer.Chapter 2:Two series 12 complexes based on 3,3',4,4'-Diphenylsulfonetetracarboxylic(H4dpstc)ligand and lanthanide ions were prepared.The impact of structures and properties on reaction conditions and auxiliary lihands were discussed.The luminescence poperties of 2,4,11 and 12 and the sensing of complex 2 were investigated.Chapter 3:With 4'-(2-sulfophenyl)-2,2':6'2,"-terpyridine(HSTP)as the first ligand,aromatic or aliphatic acid as the second ligand,we synthesized complexes 13-20.The fluorescence spectrum of complexs 13-Eu?16-Tb?18-Eu?19-Tb have been determined.Owing to 18-Eu and 19-Tb are homogeneous and have strong fluorescence emission,we synthesized a heteronuclear complex[EuxTb1-x(STP)(1,2-bdc)]n(0 ? x ? 1),and study their controllable luminescence properties.In addition,magnetic properties of 20-Dy have been investigated.
