Abstract

The invention relates to the field of magnetic properties and materials, in particular to a preparation method of a chainlike ultralow-temperature magnetics coordination polymer material, which mainly comprises the following steps: dissolving MnCl2 and amino trimethylene phosphonic acid into 10 to 30mL of deionized water according to the molar ratio of (0.5 to 1.5) : (0.5 to 1.5), adjusting pH to be 3 to 4 by using a 0.1M KOH solution, performing mechanical stirring for 2 to 4h, packaging a mixed solution in a reaction still, heating for 5 to 8d under the temperature of 140 to 160 DEG C, and cooling to room temperature, thus separating out bulk crystals. Preferably, the preparation method comprises the following steps: dissolving MnCl2 and amino trimethylene phosphonic acid into the deionized water according to the molar ratio of 1 to 1, adjusting the pH to be 3 to 4 by using the 0.1M KOH solution, then performing mechanical stirring for 3h, heating for 7d under the temperature of 150 DEG C, and cooling until the bulk crystals are separated out. The coordination compound provided by the invention has the characteristics of good heat stability, stable magnetic properties and fluorescence-emission property.

Description

technical field [0001] The invention relates to the field of magnetic properties and materials, in particular to a method for preparing a chain-like ultra-low temperature magnetic coordination polymer material. Background technique [0002] Existing studies on the magnetic properties of complexes mainly focus on ferromagnetic and antiferromagnetic transition metals and some elements in rare earth metals, and mainly test the magnetic susceptibility curve of the complexes with temperature. When the temperature drops to the Curie temperature Finally, the complexes show ferromagnetic or antiferromagnetic coupling, and the research in this area is relatively common. But there is still little research on chain-like ultra-low temperature magnetic coordination polymers. Contents of the invention [0003] The purpose of the present invention is to establish a material whose magnetic properties are controlled by temperature based on the magnetic properties of complexes. Expand the...
