Description

technical field [0001] The invention relates to the technical field of complexes, in particular to a cadmium metal organic complex and a preparation method thereof. Background technique [0002] The design and synthesis of metal-organic complexes has become a hot spot in coordination chemistry because of their novel and abundant structures and topological types, high stability, excellent optical and magnetic properties. At present, metal-organic complexes have been widely used in gas storage, gas adsorption and desorption, dye and pollutant adsorption, sensing, ion exchange, catalysis and other fields. [0003] In the preparation process of metal-organic complexes, the configuration of the ligand plays a crucial role in the final structure of the complex, which determines the structure and properties of the metal-organic complex. Several arms of multidentate V-type ligands A little twist around the central point can meet the coordination requirements, so it is possible to o...
