الإجراء التجريبي

Next, a mixed solution of 7.5 g of 1-(2-naphthyl)pyrene, 4.1 g of N-bromosuccinimide and 115 ml of dimethylformamide was heated with stirring under a nitrogen gas flow at 50° C. for 7.5 hours. After cooling the solution to room temperature, 100 ml of water was injected, followed by stirring at room temperature for 0.5 hours. The precipitated solid was collected by filtration, washed twice with 100 ml of water and then washed twice with 100 ml of methanol. The solid was washed three times with 50 ml of 1,2-dimethoxyethane and then vacuum-dried to obtain 2.0 g of 1-bromo-6-(2-naphthyl)pyrene.
