Abstract

The invention relates to a method for preparing a diamagnetic chain-shaped coordination polymer. The method comprises the following steps: dissolving 0.5-1.5mmol of Zn(NO3)2.6(H2O), 0.5-1.5mmol of 5-sulfoisophthalic acid monosodium salt and 0.5-1.5mmol of 4,4'-dipyridyl in 15-20mL of water and alcohol mixed liquid; and encapsulating in a reactor, heating for 2-4 days, and cooling to room temperature until colorless bulk single crystal is separated. The method preferably comprises the following steps: dissolving 1mmol of Zn(NO3)2.6(H2O), 1mmol of 5-sulfoisophthalic acid monosodium salt and 1mmol of 4,4'-dipyridyl in 20mL of water and alcohol mixed liquid; and encapsulating in the reactor, heating for 3 days, and cooling to room temperature until the colorless bulk single crystal is separated. Compared with the prior art, the coordination polymer material has excellent thermal stability and stable diamagnetic property, and has fluorescent emission property.

Description

technical field [0001] The invention relates to the field of magnetic properties and materials, in particular to a preparation method of a diamagnetic chain coordination polymer. 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 effects, and these aspects of research are more common. However, in the prior art, there is a lack of research on materials whose magnetic properties are controlled by temperature, especially the research on complex materials whose structures are not destroyed even when the temperature reaches 200°C. Contents of the invention [0003] The purpose of the present invention is to establish a material ...
