Abstract

The invention provides an organic electroluminescent material and application thereof. The organic electroluminescent material can provide a proper energy level; high-speed hole transport capability is realized; the organic electroluminescent material can be applied to the field of organic electroluminescence and used as a red hole transport material so as to improve the hole transport capabilityof a red organic layer material, adjust the microcavity resonance of a device, reduce the voltage of the device and improve the light efficiency of the device, sand thus the performance of an OLED device can be improved, and the application range of the OLED device can be expanded.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescence, and relates to organic electroluminescent materials and applications thereof. Background technique [0002] Compared with traditional liquid crystal technology, organic electroluminescent (OLED) technology does not require backlight illumination and color filters. Pixels can emit light by themselves and appear on a color display panel, and have self-illumination, wide viewing angles, and almost infinite height. A series of advantages such as high contrast, low power consumption, extremely high response speed, and rich colors have aroused people's great interest. [0003] Improving the performance of OLED devices has become a current research focus, mainly including: reducing the driving voltage of the device, improving the luminous efficiency of the device, and increasing the service life of the device. In order to realize the continuous improvement of the performance of OLED...
