4,4'-Bis(N-carbazolyl)-1,1'-biphenyl Usage And Synthesis | |
Classification | Carbazole derivatives, Hole-injection layer materials, Hole transport layer materials, Hole blocking layer materials, Phosphorescent host materials, Light-emitting fiodes, Organic electronics, Sublimed materials. |
Applications | 4,4′-Bis(N-carbazolyl)-1,1′-biphenyl (CBP), is one of the most widely-used host materials for efficient phosphorescent organic light-emitting diodes with high hole mobility. This is due to its electron-rich property from two carbazolyl units. It has been demonstrated that CBP can efficiently host green, yellow and red phosphorescent emitters with triplet energies smaller than that of CBP (ET = 2.6 eV). |
