Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to an organic compound, mixture and composition, and its application in the field of organic electronic devices, especially electroluminescent devices. Background technique [0002] Organic light-emitting diodes (OLEDs) have excellent properties such as light weight, active light emission, wide viewing angle, high contrast, high luminous efficiency, low energy consumption, easy fabrication of flexible and large-size panels, and are regarded by the industry as the most promising next-generation display technology . To obtain high-performance organic light-emitting diodes, the host material is the key. At present, the preparation of OLED light-emitting devices is generally made of a single-host material with a luminous body, but the single-host material will cause different carrier transfer rates, resulting in a serious roll-off of device efficiency under high bri...
