[0042] The fluorene-based terpolymer is a carbazole-fluorene-benzimidazole terpolymer, which is obtained by polymerizing a halogenated carbazole monomer, a halogenated benzimidazole monomer and a fluorene monomer.

[0043] The preparation method of described fluorenyl te...

Embodiment 1

[0146] in N 2 Under the atmosphere, put 1.49g of 2,3-naphthalene dicarboxylic anhydride, 0.27g of 3,6-dibromo-1,2-phenylenediamine, and 10mL of glacial acetic acid into the reaction vessel, stir and raise the temperature to 108°C, reflux the solvent, and carry out Constant temperature reaction for 6 hours.

[0147] After the reaction, the reaction solution was cooled to room temperature, and the crude product was gradually precipitated, filtered, and washed with deionized water until neutral. The obtained crude product was put into a vacuum drying oven for drying, the temperature of vacuum drying was 85°C, the time of vacuum drying was 12 hours, and the pressure of vacuum drying was -30kPa. The crude product after drying is separated and purified by column chromatography. The stationary phase of the chromatography column is silica gel powder, and the liquid phase is a mixed solution of dichloromethane and petroleum ether. The volume ratio of the two is 3:1 to obtain benzimida...

Embodiment 2

[0152] Accurately weigh 1.616g ferric nitrate nonahydrate (Fe(NO 3 ) 3 9H 2 (2), 2.0g urea, 20mL distilled water, 9mL ethanol and 1mL ethanolamine were added to a 100mL beaker with magnetic stirring, and after completely dissolving, 0.5g sodium nitrate and 0.5g sodium dodecyl sulfate (SDS) were added, and finally 5mL of N,N-Dimethylformamide (DMF). Stirring was stopped, and the mixed solution was ultrasonically treated for 30 min, then transferred to a washed and dried 100 mL autoclave, sealed and reacted at a constant temperature of 120 °C for 20 h. After the reaction was completed, it was cooled to room temperature, and the product was washed several times by centrifugation with deionized water and absolute ethanol, and the final product was vacuum-dried at 50°C for 6 hours to obtain reddish-brown powdery ferric oxide nanoparticles.
