CAS.1226810-15-6 2,9′-Bicarbazole

The carbazole structure is a highly conjugated aromatic system that promotes the transport of electrons and holes. The double carbazole structure endows the compound with stronger charge transfer ability, which can help optimize the charge transfer path in OLED devices and improve luminescence efficiency. In addition, carbazole compounds are commonly used in the hole transport layer (HTL) of OLEDs due to their excellent hole transport ability. 2,9 ‘- dicarbazole, as a dicarbazole structure, can enhance the transport efficiency of holes, balance the injection of electrons and holes, and help improve the luminescence efficiency of the luminescent layer.
