Embodiment 1

[0023] Such as figure 1 The preparation process shown in the preparation of 4-chloro-2-(2,6-dimethylanilinomethyl) copper phenolate complex, the specific steps are as follows:

[0024] (1) Synthesis of 4-chloro-2-(2,6-dimethylanilinomethyl)phenol ligand: Weigh 1.56g of 5-chlorosalicylaldehyde into a 100mL round bottom flask, add 30mL of ethanol and stir to dissolve , then add 20 mL of 1.21 g of 2,6-dimethylaniline ethanol solution, and add 0.05 mL of glacial acetic acid to obtain a reaction liquid; heat the reaction liquid to 76°C for reflux reaction for 1 h, cool to room temperature, let stand to precipitate solid, filter, And wash the solid with cold ethanol to finally obtain an orange-red solid which is 4-chloro-2-(2,6-dimethylanilinomethyl)phenol ligand;

[0025] (2) Synthesis of 4-chloro-2-(2,6-dimethylanilinomethyl) phenol copper complex: Weigh the 4-chloro-2-(2,6-dimethyl Add 0.52g of anilinomethyl)phenol ligand to a 100mL round-bottomed flask, add 30mL of ethanol and...

Abstract

The invention discloses a Schiff base copper complex and its preparation method and application. The preparation method comprises the following steps: (1) dissolving 5-chlorosalicylaldehyde in ethanol to obtain solution I; dissolving 2,6-dimethylaniline Dissolve in ethanol to obtain solution II; add solution II to solution I to obtain solution III; add acetic acid to solution III to obtain a reaction solution; heat the reaction solution to reflux for 1 hour, cool to room temperature, and let stand to precipitate a solid, filter, And wash the solid with cold ethanol to finally obtain the ligand; (2) dissolve the ligand synthesized in step (1) in ethanol to obtain solution IV; dissolve copper nitrate in ethanol to obtain solution V; add solution V to solution IV , to obtain a mixed solution; the mixed solution was refluxed for 1.5h, heated and filtered, the filtrate was cooled, and black blocky crystals were precipitated as complexes; the present invention explores the potential application value of Schiff base complexes in the field of luminescent materials.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescent materials and preparation methods thereof, in particular to a Schiff base copper complex and its preparation method and application. Background technique [0002] The continuous and rapid development of information technology puts forward higher requirements on the brightness, color, resolution, energy consumption, etc. of the information display system. Light-emitting diodes, thin-film electroluminescence and thick-dielectric electroluminescence have been maturely used in display technology, and organic light-emitting diodes (OLEDs) are the main players in the market. In recent years, with the market's increasing demand for high-quality, high-reliability, and large-information display devices, OLED technology has made great progress, and a variety of OLED products have been put into the market. [0003] Organic electroluminescent materials refer to polymer or small molecule or...
