Abstract
Provided are a nitrogen-containing organic compound, the use thereof, and an organic electroluminescent device using same. The nitrogen-containing organic compound has a chemical structure with pyridoquinazoline as the center, wherein one side is connected with an aryl-containing group, the other side is connected with other aryl groups having an electron transport performance, thereby forming a small molecule OLED material with an asymmetric structure, which has a good film-forming property. The molecule contains large rigid groups, and has a high thermal stability. When the nitrogen-containing organic compound is applied in OLED devices as an electron transport material, good device performances and a low voltage can be achieved.
