4,4′-Bis(N-carbazolyl)-1,1′-biphenyl (CBP), is one of the most widely-used host materials for efficient fluorescent and phosphorescent organic light-emitting diodes with high hole mobility. This is due to its electron-rich property from two carbazolyl units. | [Odor]

TGA/DSC lot specific traces available upon request | [Synthesis]
Under nitrogen protection, 150 g (369.5 mmol) of 4,4'-diiodobiphenyl, 123.5 g (738.6 mmol) of carbazole, 23 g of copper powder, 100 μL of potassium carbonate, and 500 mL of 1,3-diisopropylbenzene were added to a 2 L triple-necked flask equipped with a stirrer and condensation device. The reaction mixture was heated to reflux and maintained for 30 hours and then naturally cooled to room temperature. Subsequently, an appropriate amount of toluene was added to the reaction mixture and the insoluble material was removed by filtration. The solvent in the filtrate was removed by distillation under reduced pressure to obtain the crude product. To the crude product, 500 mL of methanol was added for recrystallization and a solid was precipitated. The crystals were collected by filtration and dried to give 122.8 g of the target product 4,4'-bis(carbazol-9-yl)biphenyl (CBP) in 68.6% yield. | [References]
