Method: Salicylhydroxamic acid, pyridine‑2‑carboxylic acid and Dy(NO 3 ) 3 ·6H 2 O is dissolved in the solvent, and a mixed solution is obtained by ultrasonication. The mixed solution is heated to reflux, and then pyridine is added to obtain a preform; the solvent is volatilized on the preform to obtain a hexanuclear dysprosium cluster ring complex single-molecule magnet. The invention can obtain a hexanuclear dysprosium cluster ring complex single-molecule magnet.

Description

technical field [0001] The invention relates to a hexanuclear dysprosium cluster ring complex single-molecule magnet and a preparation method thereof. Background technique [0002] Single-molecule magnets (Single–Molecular Magnets, SMMs) are a new type of material between molecular-based magnets and nano-magnetic materials. Because of its potential applications in high-density information processing and storage, quantum computing, molecular spintronics, etc., it has become a research hotspot in the fields of chemistry, physics, and materials science. Among the many branches of single-molecule magnets, lanthanide atoms are [Ln]4f due to their special electronic structure arrangement. n 6s 2 and [Ln]4f n-1 5d 1 6s 2 (n=1–14), reflecting the large number of single electrons of rare earth elements, significant anisotropy, and strong spin-orbit coupling, making it an ideal choice for designing single-molecule magnets. At the same time, it is found that the introduction of s...
