Abstract

The invention discloses a zinc metal complex taking (E)-4-methyl-N-((quinoline-2)methylene)aniline as a ligand and a preparation method, relates to a luminescent material and a preparation method thereof, and aims at solving the technical problems that an existing green organic luminescent material is low in luminous efficiency, poor in monochromaticity and short in service life. The molecular formula of the zinc metal complex taking (E)-4-methyl-N-((quinoline-2)methylene)aniline as the ligand is C17H14Cl2N2Zn, and the structural formula is defined in the description. The method comprises the steps that 2-quinolinecarboxaldehyde and p-toluidine are subjected to a reflux reaction under the solvothermal condition, and (E)-4-methyl-N-((quinoline-2)methylene)aniline is obtained; (E)-4-methyl-N-((quinoline-2)methylene)aniline and zinc chloride are added into acetonitrile for a reaction, and a complex is obtained. Accordingly, the zinc metal complex taking (E)-4-methyl-N-((quinoline-2)methylene)aniline as the ligand can be obtained.

Description

technical field [0001] The invention relates to a luminescent material and a preparation method thereof. Background technique [0002] With imines as ligands, novel and functional metal complexes are designed and synthesized by molecular self-assembly technology, which has the advantages of flexible design of organic substances and stable performance of inorganic substances. It not only has novel and rich topological structures, It also has potential application prospects in storage, separation, catalysis, electrical and magnetic materials, especially luminescent materials, and can be developed into new luminescent functional materials. Therefore, we hope to carry out molecular design under the guidance of theory, and change the structure and composition of molecules by means of chemical synthesis, in order to obtain luminescent materials with excellent properties. The existing green organic light-emitting materials have the technical problems of complex synthesis methods a...
