[Abstract]:As a porous material, (MOFs) has been widely used in many fields. It has aroused great concern in both academic and industrial fields. This is not only because of their aesthetic structural properties, but also because of their excellent application performance in many fields, especially in the field of catalysis. The existence of uniformly distributed active sites in MOFs. MOFs is a good heterogeneous catalyst because it contains large pore channels to ensure the accessibility of each active site. The design and synthesis of organometallic skeleton materials with functionalization has attracted much attention. The design and synthesis of organic ligands plays an important role in the construction of functional organometallic skeleton materials. The design of organic ligands with functional sites provides an excellent application value for organometallic skeleton materials. In this paper, we introduce S or thiophene into the organometallic skeleton, and use the exposed S site in the organometallic skeleton synthesized by the thiophene linear ligand to select and recognize metal ions and form coordination bonds with metal ions. In turn, it is possible to choose to adsorb metal ions. Therefore, two organic ligands containing thiophene and rare earth salts were designed to synthesize a series of metal organic skeleton materials. The synthesis method, structure, characterization and application of this material to metal ions were studied in detail. In the first chapter, the applications of organometallic skeleton materials in catalysis, fluorescence and adsorption fields and their progress in recent years are described, and the significance of this paper is introduced. In chapter 2, we have designed and synthesized organic ligands containing thiophene functional groups, [2o _ 3-b] and dithiophene -2o _ 6-dicarboxylic acid, Four coordination polymers {[Ln2L6DMF4]? 1.5H2O} n (1) (Ln=Eu (鈪，
