Embodiment

[0021] A dysprosium complex material with solvent molecular magnetic and ferroelectric responses and a preparation method thereof, the steps are as follows: 91.2 mg of Dy(NO 3 ) 3 ·6H 2 O and 77.6mg of L were mixed in a container, then 8mL of DMF and 12mL of distilled water were added, and the pH value was adjusted to 4.5 with NaOH, and ultrasonically oscillated for 20 minutes; A solid was isolated. Then washed 3 times with DMF to obtain yellow blocky crystals. The calculated yield based on dysprosium metal was 65%.

Abstract

The invention relates to an arrowhead complex material with solvent molecule-responded magnetic and ferroelectric properties and a preparation method of the arrowhead complex material. The arrowhead complex material is arrowhead (III) complex polymer simultaneously with single-molecular magnet behaviors and ferroelectric properties, has a molecular formula represented by formula (shown in the description) and is a three-dimensional porous structure containing two different coordination environment arrowhead (III) ions. The preparation method comprises the steps of dissolving Dy(NO3)3.6H2O and palmoxiric acid into a solvent, heating to react, filtering, washing to obtain solids, mixing the solids with acetone to react, heating, and drying. The arrowhead complex material has the advantages that the arrowhead complex presents the single-molecular magnet behaviors and has good ferroelectric properties, and meanwhile, the magnetic and ferroelectric properties of the arrowhead complex are can be changed along the change of solvent molecules, so that the arrowhead complex presents the solvent-responded magnetic and ferroelectric properties. The arrowhead complex material has great potential application values in solid devices such as low-temperature high-density storage equipment, nanometer devices, ferroelectric memories, integrated magnetoelectric devices and solvent photoelectromagnetic sensors.

Description

technical field [0001] The invention relates to the field of magnetic and ferroelectric dual-functional materials, in particular to a preparation method and application of a dysprosium complex magnetic material with solvent molecule magnetic and ferroelectric responses. Background technique [0002] Single-Molecular Magnets (Single-Molecular Magnets) is a new type of material between nano-magnetic materials and molecular-based magnets. In 1993, Sessoli et al. in Italy reported the first single-molecule magnet [Mn 12 o 12 (OCMe) 16 (H 2 O) 4 ], opening up a new field of magnetism (Sessoli R et al., J. Am. Chem. Soc., 1993,115,1804; Girolami et al., Science 1995,268,397). With the development of science in recent years, single-molecule magnets have attracted more and more attention from many scientists at home and abroad. As a nanometer-sized molecular-based magnet, its magnetic properties are different from the previous molecular-based magnets, which rely on the magneti...
