Abstract

The invention provides a novel organic compound and materials for organic electroluminescent devices comprising the same and organic electroluminescent devices comprising the same. The organic compound used for luminescent layer materials such as a hole injection layer material, a hole transport layer material, an electronic blocked layer material, a green phosphorescent or red main material and the like can be used for organic electroluminescent devices, thereby reducing the driving voltage, improving the luminous efficiency, the brightness, the thermostability, the colour purity, and prolonging the service life of the device.

Description

[0001] 【Technical field】 [0002] The invention relates to a novel organic compound, an organic electroluminescent device material comprising the novel organic compound and an organic electroluminescent device comprising the material. Background technique [0003] Organic electroluminescent devices are self-luminous and can be driven at low voltage. Compared with mainstream liquid crystal displays of flat panel display devices, they have excellent viewing angles and contrast ratios. They do not require a backlight, and can be lightweight and ultra-thin, which is also very advantageous in terms of power consumption. , and the color range is light, so it is attracting attention as a next-generation display. [0004] In the structure of a general organic electroluminescent device, an anode is formed on the upper part of the substrate, and a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode are sequentially formed on the upper part of the ano...
