Abstract

The invention discloses a (R, R)-1,2-diphenylethylenediamine nickel azide complex. The (R, R)-1,2-diphenylethylenediamine nickel azide complex has a chemical formula of [Ni(L)2(N3)] infinity ClO4.0.5H2O, wherein L is a chiral bidentate nitrogen-containing organic ligand. The preparation method comprises the following steps: placing a methanol solution as an underlayer in which nickel perchlorate and chiral bidentate nitrogen-containing organic ligand L are dissolved into a reaction vessel, adding a mixed solution of methanol and water as an intermediate buffer layer, slowly adding a water solution as an uppermost layer in which sodium azide is dissolved into the reaction vessel, standing for 5 days, filtering, washing and carrying out vacuum drying to obtain the target product. A novel one-dimensional chain nickel complex is prepared by using azide anion as a bridging ligand, the preparation process is simple, the reaction is carried out under a normal temperature and a normal pressure, the posttreatment is easily performed, and the yield is high and can reach 83%. The (R, R)-1,2-diphenylethylenediamine nickel azide complex has good ferroelectric property and has potential broad application prospects in the field of information storage as a novel ferroelectric material.

Description

technical field [0001] The invention belongs to the technical field of inorganic-organic hybrid molecular-based ferroelectric storage materials and their preparation and application, in particular to a (R,R)-1,2-diphenylethylenediamine compound with a noncentrosymmetric structure. Nitrogen-nickel complex is a molecular-based ferroelectric material and a preparation method thereof. Background technique [0002] Ferroelectric materials have a wide range of uses, and ferroelectric information memory can be made by using the domain flip of ferroelectrics, which is called the main storage technology in the 21st century. At present, the reported ferroelectric materials are mainly perovskite transition metal oxides, which belong to pure inorganic ferroelectric materials. However, the fact that inorganic compounds are difficult to carry out functional design and modification greatly limits the research progress in this field. Therefore, it is more practical to prepare molecular-ba...
