CAS.1454567-05-5 9-[1,1′-Biphenyl]-4-yl-9′-phenyl-3,3′-bi-9H-carbazole

The carbazole structure and biphenyl group provide an extended conjugated system, greatly enhancing the charge transfer performance of the material. This compound can optimize charge injection and balance in OLED devices by improving the transport efficiency of electrons and holes, thereby enhancing luminescence efficiency and overall device performance. In addition, carbazole compounds are commonly used in the hole transport layer (HTL) of OLEDs due to their excellent hole transport ability. The double carbazole structure of this compound can effectively improve the efficiency of hole transport, reduce charge recombination losses, and ensure efficient luminescence.
