Abstract

The invention discloses an anionic dysprosium chain complex taking organic ammonium as a counter ion as well as a preparation method and application of the anionic dysprosium chain complex. The general formula of the complex is [AH] n [Dy (L1) 3 (L2)] n, [AH] < + > is an organic tertiary ammonium cation, L1 is a beta-diketone derivative, and L2 represents an acetic acid or formate ion. Wherein the [Dy (L1) 3] module is bridged through L2 to form an anionic dysprosium chain complex structure, and the organic tertiary ammonium cation [AH] < + > is connected with a dysprosium chain through a hydrogen bond and plays a role of a counter ion of the whole complex. The complex is prepared through a conventional volatilization method, the preparation method is simple, and reaction conditions are mild; and meanwhile, the material shows a single-molecule magnet behavior with slow magnetic relaxation, and has potential application value in the field of molecule-based magnetic materials. Particularly, the anionic dysprosium chain complex can derive other compounds with various structures through changes of [AH] < + >, L1, L2 and a rare earth center, is very beneficial to regulation and control of molecular magnetism, and has not been reported in previous literatures.

Description

technical field [0001] The invention relates to the preparation and application of novel molecular-based materials, in particular to a class of anionic dysprosium-based chain complexes with organic tertiary ammonium counterions, and a preparation method and application thereof. technical background [0002] Molecular-based magnetic materials use a single molecule as a magnetic domain unit, and have the advantages of flexible structure, low density, easy tailoring, easy regulation and modification, etc., and are expected to replace the existing traditional macroscopic magnetic materials. In the future, ultra-high-density storage, quantum play an important role in computing and spintronic devices. In particular, the dysprosium complexes have become one of the ideal targets for the development of molecular-based magnetic materials, benefiting from the excellent single-ion magnetic anisotropy of dysprosium ions. However, the currently reported dysprosium complexes are mostly di...
