[0023] The above polymer functional polymer SBIDI is prepared by the following super-assembly preparation method, which specifically includes the following steps:
[0024] Step 1, under nitrogen protection, 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetraalkyl-1,1'-spirobisindene and 2,3,5 , 6-Tetrafluoroterephthalonitrile is added to the organic solvent at a molar ratio of 1.0:(0.8-1.2), and then an organic base or an inorganic base is added to obtain a mixed solution. Among them, the organic solvent is 1,4-dioxane, toluene, xylene, N,N-dimethylacetamide (DMAc), butyl acetate, dimethylsulfoxide (DMSO), N-methylpyrrolidone ( One or more of NMP). The organic base or inorganic base is piperidine, potassium tert-butoxide (t-BuOK), triethylenediamine (DABCO), 1,8-diazabicycloundec-7-ene (DBU), sodium carbonate one or more of .
[0025] Step 2, after replacing the mixed solution with nitrogen three times, react at a predetermined temperature for a predetermined time, and cool to room temp...

[0029] The preparation reaction formula of the macromolecule functional polymer SBIDI with self-microporous structure in embodiment one is as follows:
[0030]
[0031] Its specific super-assembly preparation method includes the following steps:
[0032] Step 1, under the protection of nitrogen, 3.4g (10.0mmol) of 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl-1,1'-spirobis Add indene (1a in the reaction formula) and 2.0g (10.0mmol) of 2,3,5,6-tetrafluoroterephthalonitrile (2 in the reaction formula) to a 100mL three-necked reaction flask, and then add 1, 20 mL of 4-dioxane was added, and 4.3 g (50.0 mmol) of piperidine was added to obtain a mixed solution.
[0033] Step 2: After the above mixed solution was replaced with nitrogen three times, the reaction system was reacted at 40° C. for 72 hours, and cooled to room temperature to obtain a reaction solution.
[0034] Step 3: filter the reaction solution under reduced pressure to remove the solvent 1,4-dioxane, and rinse th...

[0038] Its specific super-assembly preparation method includes the following steps:
[0039]Step 1, under the protection of nitrogen, 6.8g (20.0mmol) of 5,5',6,6'-tetrahydroxy-3,3,3',3'-tetramethyl-1,1'-spirobis Add indene (1a) and 4.0g (20.0mmol) 2,3,5,6-tetrafluoroterephthalonitrile (2) into a 250mL three-necked reaction flask, then add 40mL of dried toluene, and then add 6.7g ( 60.0mmol) of t-BuOK to obtain a mixed solution.
[0040] Step 2: After the above mixed solution was replaced with nitrogen three times, the reaction system was reacted at 80° C. for 24 hours, and cooled to room temperature to obtain a reaction solution.
[0041] Step 3: filter the reaction solution under reduced pressure to remove the solvent toluene, and rinse the filter cake with ethanol (20 mL×1 time). Then the yellow filter cake wa...
