Synthesies,Structures And Properties Of Lanthanides And Actinides Coordination Compounds

Metal-Organic Frameworks have become one of the most active research topics in structural chemistry research due to their stable framework,highly predictable topological types,easily-modified or tailored structures,and regulable functionality.It has shown potential application prospect and value in the fields of Energy gas storage and purification,molecular recognition and so on.In this thesis,a series of metal organic coordination compounds have been synthesized.The main points are as below:We have briefly reviewed the development of coordination chemistry and briefly has introduced the current research of lanthanides and actinides coordination compounds.On this basis,the author selected the basis of the topic and the main progress made in this paper.In Chapter 1 we have designed and synthesized a series of carboxylate ligands based on anthracene and anthraquinone.Reactions of this series of ligands with rare earth metals under solvothermal conditions leaded to several one-dimensional chain compounds.Among them,the compounds obtained by the reaction of anthraquinoneligands with rare earth ions show good performance for metal ion recognition.It wasunexpectedly found that the anthracene derivative ligands reacted with Co and Ni cations to give 16-membered ring-like compounds,respectively.In Chapter 2 we selected a functionalized carboxylate（H4CTC4A）as a ligand toreact with uranyl nitrate（UO₂（NO₃）₂r6H₂O）in solvothermal conditions,which resulted in a 14-nucleus zero-dimensional cage compound.Since the zero-dimensional cage compound has an anionic framework,the dye adsorption properties have been investigated.The compound can selectively adsorb cationic dyes such as EV,JB and RB but not adsorb anionic or neutral dye molecules.At the same time,we have studied the catalytic performance of this compound with the loading of Pd,Pt and Fe species.In the meantime,on the basis of the above work,we have synthesized a 3-D cage compound based on two kinds of molecular cages,which also showed a good selectivity for the adsorption of dyes.In Chapter 3,we have summarized and organized the main work during the post-graduate study,and at the meantime we have given an outlook on the future development of lanthanides and actinides coordination compounds.
