실험 절차

A mixture of 2,7-dibromo-9,9-dihexylfluorene (7) (8.0 g, 16 mmol), 2-tributylstannylthiophene (2.98 g, 8.0 mmol), tetrakis(triphenylphosphine)palladium (0) (200 mg, 1.73×10−4 mol) aqueous sodium carbonate (2M, 2 cm3), toluene (5 cm3) and ethanol (2 cm3) was heated under reflux for 24 h under argon. Toluene and ethanol were removed and hexane (10 cm3) and aqueous KI (2%, 10 cm3) added and the mixture stirred vigorously for 1 h. Diethyl ether (10 cm3) and dilute HCl(aq)(3M, 10 cm3) were added, the aqueous layer separated and washed with diethyl ether (2×10 cm3). The organic layers were combined, dried over anhydrous magnesium sulphate, filtered and concentrated to a dark brown oil which was purified by column chromatography [silica gel, hexane] to yield a pale jade coloured oil.
