CAS.2071630-78-7 5-([1,1′-biphenyl]-4-yl)-5,8-dihydroindolo[2,3-c]carbazole

The indole and carbazole structures provide excellent conjugated systems, which are crucial for charge transfer. Efficient charge transfer performance can help reduce energy loss in OLED devices, ensuring efficient recombination of electrons and holes in the emissive layer, thereby improving overall luminous efficiency. In addition, the biphenyl group and indole [2,3-C] carbazole structure in the compound give it potential optical activity and can serve as a precursor for luminescent layer materials. By modifying or coupling reactions, OLED materials with specific luminescent properties can be developed, especially for applications in blue and white light emitting devices, which have great prospects.
