A compound containing benzimidazole and its application in OLED devices |
| abstract |
The invention discloses a benzimidazole compound and its application in an organic electroluminescence device. The compound takes a benzimidazolyl ring as the core, and has the characteristics of intermolecular crystallization and aggregation, and good film-forming properties. . When the compound of the present invention is used as the host material of the light-emitting layer of the OLED light-emitting device, the current efficiency, power efficiency and external quantum efficiency of the device are greatly improved; at the same time, the life of the device is significantly improved. |
