Research Progress of Rare Earths and Tansition Metals Coordinating Supramolecular Compounds with β-diketone Ligands
Metal-organic supramolecules have a wide range of applications in the fields of luminescence,catalysis,sens-ing and magnetism,and designing functional ligands,is an important basis for the functionalization of target supramolecules.β-diketones are promising ligands because they have a variety of coordination chelation modes and can be assembled with most rare earth and transition metal ions.It has been found that the coordination of such ligands with metals can form a variety of complex structures,which has a wide range of applications in optical,electrical,magnetic,catalytic,biological and other fields.At present,most of the existing reviews are summarized from the structural characteristics,and few studies are summa-rized according to the types of coordination metals.By summarizing the existing studies,it is found that the different coordina-tion metals will affect the structures and properties of supramolecular.The organometallic complexes formed by β-diketones,rare earths and transition metals were summarized in terms of structures,properties and applications.Finally,the prospects of its application in the field of supramolecular self-assembly are discussed.
