CAS.572-83-8 2-Bromoanthraquinone

Quinone groups have strong electron acceptor properties and can stabilize electrons, making them suitable as electron transport materials or hole blocking layer materials. In OLED structures, 2-bromoanthraquinone can effectively block holes and transport electrons, helping to improve the charge balance and luminous efficiency of OLED devices. In addition, anthraquinone structures have good thermal stability, which is crucial for the long-term operation of OLED devices. High thermal stability can prevent material degradation under high brightness and high current density, thereby extending the lifespan and stability of the device.
