Abstract

The invention discloses a preparation method of a single-molecular magnet [Dy2(saph)2Cl2].4CH3OH and relates to the preparation method of the single-molecular magnet [Dy2(saph)2Cl2].4CH3OH, which is used for solving the problems that an existing synthesis method for a rear-earth cluster compound single-molecular magnet is lower in yield, complex in synthesis method of a coordination compound and incapable of carrying out mass production. The preparation method comprises the following steps: I, dissolving o-aminophenol salicylaldehyde acetal into acetonitrile to obtain liquor A; dissolving dysprosium chloride into methanol to obtain liquor B; mixing the liquor A with the liquor B, adding triethylamine with concentration of 0.001mol / L to obtain mixed liquor; II, stirring the mixed liquor obtained in the step I under the room temperature to obtain a preform; and III, volatilizing the preform in the solvent to obtain the single-molecular magnet [Dy2(saph)2Cl2].4CH3OH. The preparation method disclosed by the invention is simple, and high in yield which reaches over 45.76%. The preparation method disclosed by the invention is applied to the field of preparing the single-molecular magnets.

Description

technical field

[0001] The present invention relates to a single molecule magnet [Dy 2 (saph) 2 Cl 2 ]·4CH 3 The preparation method of OH. Background technique

[0002] Single-molecule magnets refer to those single-molecule molecules that can be magnetized under a magnetic field and remain magnetic after the magnetic field is removed. The curve of its magnetization to an external magnetic field will appear a hysteresis loop. The magnetism of single-molecule magnets is entirely derived from the individual molecules themselves, rather than relying on the long-range order and interaction of intermolecular arrangements like conventional magnets. In 1967, Wickman et al. published a paper on molecular-based magnets of iron complexes, which exhibit ferromagnetic order in the crystalline state at 2.46K. In 1993, GatteschiD et al. discovered the first single-molecule magnet Mn 12 Clusters, opening up a new field of magnetism. In the past ten years, scientists are not satisfied...
