CAS.23055-77-8 4-Bromo-4′-chloro-1,1′-biphenyl

The biphenyl structure provides a rigid, conjugated aromatic system that enhances the charge transfer properties of materials. In OLED devices, charge transfer efficiency is crucial for improving the device’s luminous efficiency and brightness. 4 ‘- Chloro-4-bromobiphenyl, through its conjugated system, helps to promote charge transport in the luminescent layer, ensuring effective recombination of electrons and holes, thereby improving the overall performance of the device. In addition, the biphenyl structure not only enhances charge transfer performance, but also has potential optical activity and can serve as a precursor for luminescent materials. Through further chemical modification, 4 ‘- chloro-4-bromobiphenyl can be used to develop OLED materials with specific emission wavelengths, particularly suitable for the development of blue, white, or green light-emitting devices.
