3,6-Diphenylcarbazole (DPhCz) is another electron-donating 9H-carbazole derivative with extended π-π conjugation from carbazole fused rings to the phenyl groups attached at 3,-6 positions. The degree of electron donating strength is in the order of carbazole 3,6-dimethylcarbazole 3,6-diphenylcarbazole, resulting in the relatively red-shift of emissions of 3,6-dimethylcarbazole and 3,6-diphenylcarbazole while comparing non-substituted carbazoles.

3Ph2CzCzBN, a highly efficient sky-blue emitter, derived from benzonitrile with four 3,6-diphenylcarbazole pendants around the benzene ring, shows a electroluminescence of 482 nm and achieves Commission Internationale de l’ Eclairage coordinates of (0.17, 0.36). Device based on the fluorescence emitter 3Ph2CzCzBN exhibits a high external quantum efficiency of 16.6% at 1000 cd m-2 with a great LT90 of 38 h.
