Embodiment 1
[0018] (1) Weigh the raw material perylenetetracarboxylic acid (10.00g, 25.51mmol) into a 500mL three-neck flask, then add 150mL of concentrated sulfuric acid, and stir at 55°C for 24h. Iodine (0.24 g, 0.95 mmol) was weighed and added to the reaction mixture, and reacted at 55° C. for 5 h. Liquid bromine (2.83 mL, 55.22 mmol) was measured and added dropwise slowly with a constant pressure funnel, and then the reactant was stirred at 85° C. for 24 h. After the reaction, blow off the remaining Br in the reaction device with nitrogen 2 , 50 mL of water was slowly dropped into the cooled reaction mixture, and the precipitate was collected by filtration. The precipitate was washed with 100 mL of 86% concentrated sulfuric acid, filtered, followed by the same operation as above with 150 mL of water, and dried to obtain the product 1,7-dibromo-perylene tetraanhydride with a yield of 85%.
[0019] (2) Weigh compound 1,7-dibromo-perylenetetraanhydride (1.65g, 3.00mmol) into a 100mL th...
Embodiment 2
[0022] (1) Weigh the raw material perylenetetracarboxylic acid (10.00g, 25.51mmol) into a 500mL three-neck flask, then add 150mL of concentrated sulfuric acid, and stir at 55°C for 24h. Iodine (0.24 g, 0.95 mmol) was weighed and added to the reaction mixture, and reacted at 55° C. for 5 h. Liquid bromine (2.83 mL, 55.22 mmol) was measured and added dropwise slowly with a constant pressure funnel, and then the reactant was stirred at 85° C. for 36 h. After the reaction, blow off the remaining Br in the reaction device with nitrogen 2 , 50 mL of water was slowly dropped into the cooled reaction mixture, and the precipitate was collected by filtration. The precipitate was washed with 100 mL of 86% concentrated sulfuric acid, filtered, followed by the same operation as above with 150 mL of water, and dried to obtain the product 1,7-dibromo-perylene tetraanhydride with a yield of 83%.

Embodiment 3
[0026](1) Weigh the raw material perylenetetracarboxylic acid (10.00g, 25.51mmol) into a 500mL three-neck flask, then add 150mL of concentrated sulfuric acid, and stir at 55°C for 24h. Iodine (0.24 g, 0.95 mmol) was weighed and added to the reaction mixture, and reacted at 55° C. for 5 h. Liquid bromine (2.83 mL, 55.22 mmol) was measured and added dropwise slowly with a constant pressure funnel, and then the reactant was stirred at 85° C. for 48 h. After the reaction, blow off the remaining Br in the reaction device with nitrogen 2 , 50 mL of water was slowly dropped into the cooled reaction mixture, and the precipitate was collected by filtration. The precipitate was washed with 100 mL of 86% concentrated sulfuric acid, filtered, followed by the same operation as above with 150 mL of water. After drying, the product 1,7-dibromo-perylene tetraanhydride was obtained with a yield of 84%.
