Embodiment 1
[0066] The synthesis of embodiment 1TBPIM100
[0067] Add 3.001g of tetrafluoroterephthalonitrile to the reactor equipped with a water separator, and 4.290g of 15mmol 2,3,8,9-tetraphenol hydroxyl-6H,12H-5,11-methylenediphenyl And[b,f][1,5]diazapine, 6.21g anhydrous K 2 CO 3 and 30ml N,N-dimethylacetamide, stir well. Under nitrogen, the reaction device was transferred to an oil bath at 155° C., stirred mechanically, and the reaction was continued for 30 minutes. After the reaction system was cooled, the reaction product was poured into methanol for precipitation. The obtained precipitate was filtered, dissolved in chloroform, and then precipitated into methanol, and repeated three times. Finally, the obtained yellow solid was placed in boiling water, boiled for 5-8 hours, and vacuum-dried at 80° C. for 20 hours to obtain the target product for use. The target product is insoluble in common solvents, specific surface area = 560m 2 / g.
Embodiment 2
[0068] The synthesis of embodiment 2TBPIM60
[0069] Add 3.001g of tetrafluoroterephthalonitrile to the reactor equipped with a water separator, and 2.040g of 5,5',6,6'-tetrahydroxy-3,3',3,3'-tetramethyl Spirobisindene and 2.574 g of 15 mmol 2,3,8,9-tetraphenolic hydroxy-6H,12H-5,11-methylenedibenzo[b,f][1,5]diazocine, 6.21g anhydrous K 2 CO 3 and 30ml N,N-dimethylacetamide, stir well. Under nitrogen, the reaction device was transferred to an oil bath at 155° C., stirred mechanically, and the reaction was continued for 30 minutes. After the reaction system was cooled, the reaction product was poured into 500ml of methanol for precipitation. The obtained precipitate was filtered, dissolved in chloroform, and then precipitated into methanol, and repeated three times. Finally, the obtained fluorescent yellow solid was placed in boiling water, boiled for 5-8 hours, and vacuum-dried at 80° C. for 20 hours to obtain the target product for use. The target product characterizati...
