Abstract

The invention discloses a magnesium-doped metal-organic frame DMMg0.5Co0.5F single-crystal material and a preparation method thereof. The magnesium-doped metal-organic frame DMMg0.5Co0.5F single-crystal material is composed of a DMMg0.5Co0.5F single crystal with the size of 2.0*2.0*1.0-2.5*2.5*1.5 mm<3>, wherein the mol ratio of a magnesium ion to a cobalt ion in the compound is 1:1. The used reagent is a business product and is not prepared through a tedious preparation; a novel metal-organic frame single-crystal material and a large single crystal can be obtained through the combination of a hydrothermal method and a liquid phase method; and the process is strong in controllability and easy to operate and the purity of the obtained product is high. The magnesium-doped DMCoF single-crystal material obtained from the invention is expected to be widely used in a novel metal-organic frame semiconductor, information storage and an optical apparatus.

Description

technical field [0001] The present invention relates to a magnesium-doped metal-organic framework single crystal material and a preparation method thereof, in particular to a Mg-doped [(CH 3 ) 2 NH 2 ]Co(HCOO) 3 Single crystal material (abbreviated as DMMg 0.5 co 0.5 F, DM is [(CH 3 ) 2 NH 2 ] +1 , F is [(HCOO) 3 ] -3 ) and its preparation method. technical background [0002] Metal-Organic Frameworks (MOFs) materials have attracted widespread attention due to their potential applications in catalysis, hydrogen storage, and optical components, and are currently a hot spot in the field of new functional materials research. Due to the advantages of flexible preparation, flexible framework, easy tailoring, and easy formation of highly anisotropic and low lattice symmetry structures, people have tried to combine ferroelectric organic compounds with magnetic transition metal ions in recent years to design Novel multiferroic materials based on metal-organic hybrids. ...
