Abstract

The invention discloses a blue fluorescence doped material with high efficiency and long service life, application thereof and an organic electroluminescent device. The structural general formula of the blue fluorescence doped material is shown in the specification. When the blue fluorescence doped material is applied to the organic electroluminescent device, the light-emitting efficiency is improved to a certain extent under the same current density, the starting voltage of the device is reduced to a certain extent, the power consumption of the device is relatively reduced, and the service life of the device is correspondingly prolonged.

Description

technical field

[0001] The technical field of organic electroluminescence of the present invention specifically relates to a high-efficiency, long-life blue fluorescent doped material and its application and an organic electroluminescent device. Background technique

[0002] As the next-generation flat-panel display technology, organic light-emitting diodes (OLEDs) have the advantages of active light emission, low driving voltage, fast response speed, wide viewing angle, light and thin devices, and flexible display. wide attention from the world and industry. To realize the full-color display of OLEDs, red, green, and blue primary color light-emitting materials are essential. Among them, the blue light material is particularly important, it can not only provide the necessary blue emission light, but also obtain green light and red light through energy transfer. Moreover, blue light materials are also the key to effectively reducing the energy consumption of full-color OLED...
