Embodiment 1
[0048] Add 2.14 g of 3,4,9,10-perylenetetracarboxylic dianhydride (PTDA) (M=392) into 18 mL of concentrated (98%) H 2 SO 4 (M=98, 1.836g / mL) in a three-necked flask, oscillated by 35Hz ultrasonic waves for 10min, then placed it on a heat-collecting constant temperature magnetic stirrer and added a condensing device, stirred at room temperature for 6h, and then adjusted the temperature to 80 ℃, reflux reaction, adding 0.053gI 2 (M=127) was used as a catalyst and about 0.577mL (3.12g / mL) of liquid bromine (M=160) was slowly added dropwise into it using a constant pressure dropping funnel. After reacting for 24 hours, dilute the reaction solution with concentrated sulfuric acid to 60% with distilled water, then suction filter to obtain a filter cake, and dry the filter cake in a vacuum oven at 90°C for 24 hours. The filter cake mainly contains the aforementioned three compounds a, b, and c, where a:b:c=7:2:1.

Embodiment 2
[0054] Add 2.09 g of 3,4,9,10-perylenetetracarboxylic dianhydride (PTDA) (M=392) into 18 mL of concentrated (98%) H 2 SO 4 (M=98, 1.836g / mL) in a three-necked flask, oscillated by 35Hz ultrasonic waves for 10min, then placed it on a heat-collecting constant temperature magnetic stirrer and added a condensing device, stirred at room temperature for 6h, and then adjusted the temperature to 80 ℃, reflux reaction, adding 0.052gI 2 (M=127) was used as a catalyst, and about 0.58 mL (3.12 g / mL) of liquid bromine (M=160) was slowly added dropwise into it using a constant pressure dropping funnel. After reacting for 24 hours, dilute the reaction solution with concentrated sulfuric acid to 60% with distilled water, then suction filter to obtain a filter cake, and dry the filter cake in a vacuum oven at 90°C for 24 hours. The filter cake mainly contains the aforementioned three compounds a, b, and c, where a:b:c=7:2:1.

Embodiment 3
[0060] Add 1.98 g of 3,4,9,10-perylenetetracarboxylic dianhydride (PTDA) into 18 mL of concentrated (98%) H 2 SO 4 In a three-necked flask, oscillate with 35Hz ultrasonic waves for 10min, then place it on a heat-collecting constant temperature magnetic stirrer and add a condensing device, stir at room temperature for 6h, adjust the temperature to 80°C, reflux reaction, and add 0.052gI 2 As a catalyst, about 0.58 mL of liquid bromine was slowly added dropwise into it with a constant pressure dropping funnel. After reacting for 24 hours, dilute the reaction solution with concentrated sulfuric acid to 60% with distilled water, then suction filter to obtain a filter cake, and dry the filter cake in a vacuum oven at 90°C for 24 hours. The filter cake mainly contains the aforementioned three compounds a, b, and c, where a:b:c=7:2:1.
[0061] In a 100ml three-necked reaction flask, add 0.95g of bromoperylenetetraanhydride prepared by the above steps, 0.52mL of 17.5mol / L catalyst ac...
