Abstract

The invention discloses a mononuclear dysprosium complex and a preparation method and application thereof. The chemical formula of the complex is [Dy(HL)2(CH3OH)Cl3], wherein HL is 2-methyl-5,7-dibromo-8-hydroxyquinoline. The complex belongs to a monoclinic system and P21 / n space groups. The preparation method of the mononuclear dysprosium complex includes the steps that DyCl3.6H2O and 2-methyl-5,7-dibromo-8-hydroxyquinoline are taken and dissolved with a mixed solvent, the pH of the obtained solution is adjusted to range from 6.5 to 7.8, the obtained mixed liquid reacts under the heating condition, and then the complex is obtained, wherein the mixed solvent is a composition of methyl alcohol and acetonitrile. The preparation method of the complex is simple, the cost is low, good repeatability is achieved, magnetic properties of the complex are shown as field-induced single-molecular magnet behaviors, and the complex can be used for preparing magnetic materials.
