Description

technical field [0001] The invention relates to the field of organic electroluminescent devices, in particular to an organic compound and the application of the organic compound in organic electroluminescent devices, and an organic electroluminescent device containing the organic compound. Background technique [0002] Compared with traditional liquid crystal technology, organic electroluminescence (OLED) technology does not require backlight illumination and color filters. Pixels can emit light by themselves and be displayed on a color display panel. Moreover, it has ultra-high contrast and ultra-wide viewing Angle, curved surface, thin and other characteristics. [0003] The performance of OLED is not only affected by the light emitter, in particular, the materials that form each layer of OLED have a very important influence on the performance of OLED, such as substrate material, hole blocking material, electron transport material, hole transport material and electron or ...
