Embodiment 1
[0041] Embodiment 1: the preparation of polymer P1
[0042] (1) In a 500 mL two-necked flask, p-aminophenylcarbazole (15.49 g, 60 mmol) was dissolved in 120 mL of dichloromethane, and then 24 mL of triethylamine was added. While stirring under nitrogen atmosphere at room temperature, a solution of 2,6-difluorobenzoyl chloride (11.08 g, 63 mmol) in dichloromethane (120 mL) was slowly added dropwise to the above solution. The reaction was stirred at room temperature for 12h. The solution was washed with water, and the solvent was removed by evaporation. The crude product was recrystallized from a mixture of ethanol and water with a volume ratio of 10:1 to obtain white crystals, which were the product difluoromonomer M1 (20.53 g, 86%). 1HNMR (DMSO-d, rt, 300MHz): δ11.11(s, NH, 1H), 8.26-8.24(d, CH, 2H), 8.02-8.00(d, CH, 2H), 7.65(d, CH, 2H), 7.62(t, CH, 1H), 7.44(d, CH, 1H), 7.41(d, CH, 1H), 7.33-7.30(t, CH, 2H), 7.29-7.26(t, CH, 2H ).

Embodiment 2
[0045] Embodiment 2: the preparation of polymer P2 series
[0046] (1) Dissolve p-aminophenyl bis-tert-butylcarbazole (18.50 g, 50 mmol) in 100 mL of dichloromethane in a 500 mL two-necked flask, and then add 20 mL of triethylamine. While stirring under nitrogen atmosphere at room temperature, a solution of 2,6-difluorobenzoyl chloride (9.15 g, 52 mmol) in dichloromethane (100 mL) was slowly added dropwise to the above solution. The reaction was stirred at room temperature for 12h. The solution was washed with water, and the solvent was removed by evaporation. The crude product was recrystallized from a mixture of ethanol and water with a volume ratio of 10:1 to obtain white crystals which were the product difluoromonomer M2 (23.62 g, 92%). 1HNMR(DMSO-d,rt,300MHz):δ11.07(s,NH,1H),8.29(d,CH,2H),7.98-7.95(d,CH,2H),7.66(d,CH,2H) ,7.62(t,CH,1H),7.59(d,CH,1H),7.49(d,CH,1H),7.33-7.30(t,CH,2H),7.29-7.26(t,CH,2H), 1.42 (s, CH, 9H).

Embodiment 3
[0050] Embodiment 3: the preparation method of polymer P7
[0051] (1) In a 500 mL two-necked flask, p-aminotriphenylamine (13.02 g, 50 mmol) was dissolved in 100 mL of dichloromethane, and then 20 mL of triethylamine was added. While stirring under nitrogen atmosphere at room temperature, a solution of 2,6-difluorobenzoyl chloride (9.15 g, 52 mmol) in dichloromethane (100 mL) was slowly added dropwise to the above solution. The reaction was stirred at room temperature for 12h. The solution was washed with water, and the solvent was removed by evaporation. The crude product was recrystallized from a mixture of ethanol and water with a volume ratio of 10:1 to obtain light blue crystals which were the product difluoromonomer M7 (18.03 g, 90%). 1HNMR (DMSO-d, rt, 300MHz): δ10.79(s, NH, 1H), 7.65(d, CH, 1H), 7.62(d, CH, 2H), 7.58-7.56(m, CH, 4H) , 7.31-7.22 (m, CH, 6H), 7.05-7.00 (m, CH, 4H).
