General synthetic procedure for various 2,6-bis(p-dialkylaminostyryl)-9,10-distyrylanthracenes (FCn) Potassium tert-butoxide (0.16 g, 1.43 mmol) was added to the mixture of 2,6-bis(diethylphosphorylmethyl)-9,10-distyrylanthracene (0.13 g, 0.19 mmol) and 4-dialkylamino benzaldehyde (0.56 mmol) in anhydrous THF (15 mL) at room temperature under N2 protection. The mixture was stirred overnight and then 100 mL of methanol was added. The precipitate was collected and purified by column chromatography on silica gel using hexane–CH2Cl2 (3/1) as the eluent. The green to orange solids were obtained in 57–73% yields, and their 1H and 13C NMR data and element analysis were as follows. |
