実験手順

Under a nitrogen gas atmosphere, 289 mg (0.235 mmol) of butylphenylsilane (compound 14), 750 mg (1.17 mmol) of 9,9-dioctylfluorene with boron structures introduced onto the 2 and 7 positions, 515 mg (0.935 mmol) of 2,7-dibromo-9,9-dioctylfluorene, 2.22 g (16.1 mmol) of potassium carbonate, 15 ml of THF and 8 ml of distilled water were added to a 100 ml three-necked flask equipped with a reflux condenser, and this mixture was heated to 60° C. After the dissolution of the substrate was confirmed, one full spatula of tetrakis(triphenylphosphine)palladium was added, and the mixture was heated and agitated for approximately 48 hours. When toluene was added following cooling and the solvent was distilled away as far as possible, a high-viscosity substance was obtained.
