実験手順

Next, a mixed solution of 1.3 g of 1,6-bis(4-methylphenyl)pyrene, 0.6 g of N-bromosuccinimide and 30 ml of dimethylformamide was stirred under nitrogen gas stream at a temperature of 60° C. for 5 hours. After cooling the mixed solution to room temperature, 30 ml of water was injected thereinto to extract therefrom with 100 ml of dichloromethane. The organic layer was washed twice with 50 ml of water, dried by magnesium sulfate and thereafter evaporated. The organic layer was recrystallized from toluene and vacuum dried to thereafter obtain 0.7 g of 3-bromo-1,6-bis(4-methylphenyl)pyrene.
