The invention provides a phenazine derivative, a preparation method and application thereof, and relates to the technical field of organic photoelectric materials. By optimizing the molecular structure design, the phenazine derivatives obtained in the present invention have higher light extraction efficiency and can be used to prepare organic electroluminescent devices, especially as light extraction materials in organic electroluminescent devices, which can effectively improve the efficiency of OLEDs. The luminous efficiency of the device is better than that of the existing commonly used OLED devices. The invention also provides a preparation method of phenazine derivatives, which is simple and has easy-to-obtain raw materials. |
