Problems solved by technology

In 2003, Riel et al. tried to vapor-deposit the inorganic compound ZnSe with a high refractive index (n=2.6) on the cathode, and use the difference in refractive index between the functional layers to improve the light extraction efficiency, but it was limited by the evaporation of inorganic materials. Due to the high temperature and slow evaporation rate, these compounds have not been widely used in organic electroluminescent devices.

specific Embodiment

[0172] The synthesis method of the compound according to the present invention is exemplified, but the present invention is not limited to the following examples.

[0173]

[0174] Synthesis of Compound C-1:

[0175]

[0176] Weigh magnesium (1.49g, 62mmol) and iodine into a 250mL three-necked flask, add 25ml of anhydrous tetrahydrofuran, replace nitrogen and add 4-bromotriphenylamine (10g, 31mmol), heat to initiate the reaction, and place at 65°C for 2h. The Grignard reagent was prepared after the reaction liquid was cooled to room temperature. Weigh cyanuric chloride (5.67g, 31mmol) into a 250mL flask, and add about 80mL of tetrahydrofuran. After replacing the nitrogen, the Grignard reagent was added slowly, and stirred overnight at room temperature. After the reaction was complete, it was quenched with water, extracted with ethyl acetate, dried over anhydrous sodium sulfate, mixed with silica gel and purified by column chromatography to obtain 4.85 g of an interme...

Abstract

The invention relates to the technical field of organic electroluminescence, in particular to a heterocyclic arylamine compound and application of the heterocyclic arylamine compound on electronic devices, especially applications of the heterocyclic arylamine compound on organic light-emitting diodes. The heterocyclic arylamine compound disclosed by the invention has a proper energy level, has a relatively high extinction coefficient in the ultraviolet region and a relatively high refractive index in the visible light region, and can be used as a light extraction layer in devices. Damage of external high-energy light on internal materials of organic electroluminescence display equipment can be reduced, the light extraction rate is increased, and the light emitting efficiency of devices isimproved.

Description

[0001] This application claims the priority of the Chinese patent application submitted to the China Patent Office on December 10, 2018, with the application number 201811503262.4 and the title of the invention is "a heterocyclic aromatic amine compound and its application in organic electronic devices", all of which The contents are incorporated by reference in this application. technical field [0002] The invention relates to the technical field of organic electroluminescence, in particular to a heterocyclic aromatic amine compound and composition, and its application in organic electronic devices, especially in electroluminescent devices. Background technique [0003] Organic electroluminescent display devices are a type of self-luminous display devices, which generate excitons through the transfer and recombination of carriers between functional layers, and rely on organic compounds or metal complexes with high quantum efficiency to emit light. It has the characteristic...
