Procedure

Next, a mixed solution of 1.8 g of 1,6-bis(4-fluorophenyl)pyrene, 835 mg of N-bromosuccinimide and 60 ml of dimethylformamide was stirred under a nitrogen gas flow at 80° C. for 5 hours. After cooling the solution to room temperature, the resultant precipitate was filtered. The solid was washed with 30 ml of methanol and then vacuum-dried to obtain 951 mg of 3-bromo-1,6-bis(4-fluorophenyl)pyrene.
