[0262] (Synthesis of Compound E and Compound F)
[0263] -Synthesis of Compound A-
[0264] Under an inert atmosphere, add 5.00 (29mmol) of 1-naphthylboronic acid, 6.46g (35mmol) of 2-bromobenzaldehyde, 10.0g (73mmol) of potassium carbonate, 36ml of toluene and 36ml of ion-exchanged water to a 300ml three-necked flask. While stirring, argon was blown for 20 minutes. Then, 16.8 mg (0.15 mmol) of tetrakis(triphenylphosphine)palladium was added, and argon was blown for 10 minutes while stirring at room temperature. The temperature was raised to 100°C, and the reaction was carried out for 25 hours. After cooling to room temperature, the organic layer was extracted with toluene, and the obtained organic layer was dried over sodium sulfate, and the solvent was distilled off. The compound thus obtained is purified with a silica gel column using a mixed solvent of toluene:cyclohexane=1:2 (volume ratio) as a developing solvent to obtain the following formula:

[0300]
[0301] Under an argon atmosphere, 17.0 g (28.4 mmol) of compound E synthesized in the same manner as above, 19.4 g (28.0 mmol) of compound F synthesized in the same manner as above, and 311 mL of toluene were added to a 1 L three-neck flask connected to a Dimroth condenser. , and then the gas in the container was replaced with nitrogen by blowing nitrogen. After raising the temperature to 45°C, 19 mg of palladium acetate and 118 mg of tris(o-methoxyphenyl)phosphine were added, and after stirring at 45°C for 5 minutes, 25.9 mL of a 33% by weight bis(tetraethylammonium)carbonate aqueous solution was added. , stirred at 114°C for 24 hours. Then, 5.27 g (30.8 mmol) of 4-bromotoluene was added and stirred at 114° C. for 1 hour, and then 5.48 g (30.8 mmol) of 4-tert-butylphenylboronic acid was added and stirred at 114° C. for 1 hour. Cool to 65 DEG C, wash 2 times with 5% by weight sodium diethyldithiocarbamate aqueous solution, wash 2 times with 2N hydrochloric acid, wa...

[0305]
[0306] Under an argon atmosphere, polymer 1 (1.0 g, 2.28 mmol in terms of benzofluorene repeating units) and 50 mL of chloroform were placed in a 100 mL flask, stirred and dissolved at room temperature, and then 3.5 mL of trifluoroacetic acid was added in sequence. , 91 µL of bromine (1.78 mmol, 78 mol% relative to the benzofluorene unit), and stirred for 6 hours under light shielding. The reactant was dropped into 250 mL of methanol under stirring to cause precipitation. The obtained precipitate was filtered, washed with methanol, and dried under reduced pressure to obtain 1.09 g of a polymer. The polymer was placed in a 100 mL flask under an argon atmosphere, 50 mL of chloroform was charged therein, stirred and dissolved at room temperature, and then 3.4 mL of trifluoroacetic acid and 41 μL of bromine (0.80 mmol, relative to the benzofluorene unit 36 mol%), stirred for 17 hours under light shielding. The reactant was dropped into 250 mL of methanol under stirrin...
