Embodiment 1
[0022] Add 200ml of anhydrous toluene into a 500ml dry three-neck flask, vacuumize and fill with argon three times. Under the protection of argon, pipette 3.3715 ml of phenyltrichlorosilane into the toluene solution with a dry pipette, and stir. Weigh 2.3228g of 1,6-diaminopyrene and dissolve it in 100ml of anhydrous toluene, then add 16.8ml of anhydrous triethylamine to this solution, and mix well. At 0°C, use a dry constant pressure dropping funnel to slowly add this solution dropwise into the solution in a three-neck flask, and finish dropping within 24 hours. The reaction solution was continued to react at 0°C for 48 hours. Under the protection of argon, the triethylamine hydrochloride generated in the reaction was quickly filtered off to obtain a superstructured Ph-LS solution.
[0023] Under the protection of argon, the obtained Ph-LS solution was quickly transferred to a 500ml three-neck flask and stirred. Add 0.36 g of deionized water and 100 ml of anhydrous toluene...
Embodiment 2
[0025] Add 200ml of anhydrous toluene into a 500ml dry three-neck flask, vacuumize and fill with argon three times. Under the protection of argon, pipette 3.3715 ml of phenyltrichlorosilane into the toluene solution with a dry pipette, and stir. Weigh 2.3228g of 1,6-diaminopyrene and dissolve it in 100ml of anhydrous toluene, then add 16.8ml of anhydrous triethylamine to this solution, and mix well. At 25°C, use a dry constant pressure dropping funnel to slowly add this solution dropwise into the solution in a three-necked flask, and finish dropping in 48 hours. The reaction solution was continued to react at 25° C. for 48 hours.
[0026] Add 0.36 g of deionized water and 100 ml of anhydrous toluene / anhydrous dioxane mixed solution (60 / 40) into the constant pressure dropping funnel respectively. At 25°C, this solution was slowly added dropwise into a three-necked flask, and triethylamine salt was rapidly formed, which was completed in 24 hours, and then continued to react fo...
