| Synthesis | General procedure for the synthesis of 3,6-dibromo-9-(4-bromophenyl)-9H-carbazole from 9-(4-bromophenyl)carbazole:
1. 9-(4-bromophenyl)-9H-carbazole (0.1 g, 0.31 mmol, 1 eq.) was dissolved in DMF to prepare a solution.
2. A DMF solution (3.5 mL) of N-bromosuccinimide (0.12 g, 0.69 mmol, 2.2 eq.) was slowly added dropwise to the above solution under stirring.
3. The reaction mixture was stirred continuously for 3 hours at room temperature.
4. Upon completion of the reaction, water was added to the mixture and a white precipitate was precipitated.
5. The precipitate was purified by hexane recrystallization to give a white solid product (0.082 g, 55% yield).
