Disclosed are a nitrogen-containing heterocyclic compound and an application thereof, the nitrogen-containing heterocyclic compound having the structure shown in general formula (1) and, when used in an OLED, particularly as the main material of a light emitting layer, the external quantum efficiency of the device can be improved and the service life of the device can be increased. In addition, the compound not only has a relatively stable eight-membered ring structure, but also has a relatively large ring structure, so that a conjugated system can be added, making the structure more stable and increasing the stability of the device, and also reducing the starting voltage to increase the service life of the device. |
