Embodiment 1

[0108]

[0109] In a nitrogen atmosphere, 10.0 g (10.9 mmol) of intermediate M-3-1-1, 3.15 g (13.08 mmol) of 2-chloro-4-phenylquinazoline and 0.27 g of 0.27 g (0.22 mmol) ) of tetrakis (triphenylphosphine) palladium is put into a flask and dissolved in a mixed solvent of 250ml of toluene, ethanol and water (volume ratio 3:1:1); then, the aqueous solution of potassium carbonate of 6g (43.6mmol) Add in the above reactant, then reflux and stir for 12 hours, after the reaction, extract the reactant with ethyl acetate; dry the extracted product with magnesium sulfite and filter, then, concentrate and filter the product under reduced pressure, use silica gel column chromatography (developing Agent ratio: petroleum ether / dichloromethane=3:1) to purify the concentrated product to obtain 9.4g of compound 28 (yield=87%), mass spectrum: theoretical value: 995.31; measured value: 995.32.

Embodiment 2

[0111]The same preparation method as in Example 1, the difference is that 2-chloro-4-phenylquinazoline is replaced by 4-bromobiphenyl to obtain 8.74g of compound 80 (yield=85%), mass spectrum: theoretical value : 943.31; The measured value is 943.33.

Abstract

The invention provides a new-type arylamine derivative. The compound is used for an organic electroluminescence diode and a display device comprising the organic electroluminescence diode. At least one layer, especially a hole transmitting layer, of the organic electroluminescence diode contains the arylamine derivative as shown in formula (1), so the organic electroluminescence diode has appropriate heat stability, a lower driving voltage, longer service life and high luminous efficiency.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescent devices, in particular to an aromatic amine derivative, its preparation method and application. Background technique [0002] The organic electroluminescence element is a self-luminous element utilizing the principle that a fluorescent substance emits light by recombination energy of holes injected from the anode and electrons injected from the cathode by applying an electric field. The structure of the organic electroluminescent element is specifically: an anode, a cathode and an organic layer between them. In order to improve the efficiency and stability of organic electroluminescent elements, organic material layers include multiple layers with different materials, such as hole injection layer (HIL), hole transport layer (HTL), light emitting layer, electron transport layer (ETL) and electron injection layer (EIL). [0003] In such an organic light emitting diode, when a vo...
