Abstract

The invention provides an organic electroluminescent material and its application. The organic electroluminescent material has high electron transport capability, and can be used as an electron transport layer in an organic electroluminescent device, which can reduce the driving voltage of the device and improve the performance of the device. The luminous efficiency prolongs the life of the device, thereby expanding the application range of the device.

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...
