| Hazard Information | Back Directory | [Description]
3,6-Diphenyl-9H-carbazole, also known as 3,6-Diphenylcarbazole (DPhCz), is another electron-donating 9H-carbazole derivative that has an extended π-π conjugation from the carbazole fusion ring to the phenyl group attached to the 3,-6 position. 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. | [Synthesis]
Under nitrogen protection, 3,6-dibromocarbazole (5 g, 15.4 mmol), phenylboronic acid (4.1 g, 33.9 mmol), palladium triphenylphosphine (0.7 g, 0.6 mmol) and toluene (45 ml) were sequentially added to a dry reaction flask. Subsequently, 2M aqueous sodium carbonate solution (45 ml) was slowly added. The reaction mixture was stirred at 80°C for 8 hours. After completion of the reaction, the organic phase was separated and concentrated under reduced pressure using a rotary evaporator. Finally, the concentrated residue was purified by silica gel column chromatography to afford the target product 3,6-diphenylcarbazole (3.6 g, 74% yield). | [References]
