Problems solved by technology

Although it has been reported in the literature that the gain and loss of crystallization solvent molecules can be used to regulate the magnetic behavior of complexes, only two examples of transition metals have been reported for single-chain magnet molecular magnetic switches, and the construction of 3d–4f single-chain magnet molecules with slow relaxation behavior Magnetic switches are currently not reported in the literature

Embodiment 1

[0021] Embodiment 1: Complex [Cu 3 Tb 2 (Htris) 2 (H 2 tris) 2 (NO 3 ) 6 ]·2C 2 h 5 Preparation of OH: Weigh Cu(OAc) in sequence 2 ·H 2 O (0.1mmol, 0.0199g), Tb (NO3) 3 ·5H 2 O (0.2mmol, 0.0906g) and H 3 Tris (0.2mmol, 0.023g) was placed in a glass tube with an inner diameter of about 1.0cm and a length of about 20cm with one end sealed, and 2.0mL of LC was added to it 2 h 5 OH solution. Shake the mixture well and seal it tightly with a liquefied gas flame under vacuum. Place it in an oven at 80°C for three days, take it out and slowly cool it down in an incubator for 24 hours, and observe blue rectangular crystals under a microscope. Vacuum drying, weighing 0.0455g, yield: 60%

Abstract

The invention discloses a terbium copper hetero-metal coordination polymer with a single-chain magnet magnetic switch effect and a preparation method of the terbium copper hetero-metal coordination polymer. A chemical formula of the polymer is as follows: [Cu3Tb2(Htris)2(H2tris)2(NO3)6].2C2H5OH. The preparation method comprises the following steps: successively weighing Cu(OAc)2.H2O, Tb(NO3)3.5H2O and H3tris, and dissolving in absolute ethyl alcohol, placing an obtained mixed solution in a container, vacuumizing, sealing, reacting under a heating condition, cooling, and thus obtaining a target product. A research result shows that when free object ethanol molecules are not lost, the coordination polymer has a slow relaxation behavior; and after the free ethanol molecules are lost, the coordination polymer does not have the slow relaxation behavior at all, so that the single-chain magnet magnetic switch effect is realized by successively utilizing the obtaining and loss of the object molecules.

Description

technical field [0001] The invention relates to molecular-based magnetic functional materials, in particular to a copper terbium heterometallic coordination polymer with a single-chain magnet magnetic switching effect and a preparation method thereof. Background technique [0002] The application of 3d–4f heterometallic coordination polymers in the field of molecular-based magnetic materials has attracted the attention of many researchers, and thus has become one of the research hotspots. Among them, the high-end application of molecular-based magnetic materials in the fields of high-density magnetic memory and magnetic thin films has put forward new requirements for them. It is hoped that the magnetic properties of the magnetic materials used can be controlled at will, that is, they have a magnetic property switching effect. In 2009, the research group of French scientist J.M.Vincent reported on Inorg.Chem. a report on the influence of crystallization solvent water molecule...
