10-Bromo-7H-benzo[c]carbazole Usage And Synthesis

Uses

10-Bromo-7H-benzo[c]carbazole is an electroluminescent material.

Synthesis

The 20.4g (0.1mol) 7H- benzo [c] carbazole was dissolved in tetrahydrofuran (THF, 500mL), and then the resulting solution was stirred at 0 10 minutes. Thereto was added N- bromosuccinimide (NBS, 18.68g, 0.105mol), the resulting mixture was stirred at normal temperature for 12 hours, then extracted with ethyl acetate and distilled water. The organic layer was dried over anhydrous magnesium sulfate (MgSO4) was dried, and then the solvent was removed and subjected to silica gel column chromatography to give 25.4g (86percent) 10-Bromo-7H-benzo[c]carbazole.
