Other 9,9-dialkylfiuorene-carbaldehyde intermediates were synthesized as described for 9,9-didodecylfluorene-2-carbaldehyde except that different 1-alkylbromides were used. After purification, they were used without characterization. 9,10-Bis[(9,9-didodecylfluorene-2-yl)vinyl]anthracene (FLAC12). 9,9-Didodecylfluorene-2-carbaldehyde (0.167 g, 0.46 mmol) and 9,10-bis(diethylphosphorylmethyl)anthracene (0.10 g, 0.21 mmol) were dissolved in 20 mL of anhydrous THF. Potassium tert-butoxide (0.19 g, 1.67 mmol) was added and the resulting suspension was stirred for 5 h at room temperature. Methanol was added into the mixture and the resulting solid was collected by filtration. The crude product was purified by silica gel column chromatography (petroleum ether/dichloromethane ¼ 4/1, v/v). After recrystallization from chloroform– methanol, a yellowish-green solid was obtained (0.19 g, 75% yield). |

其它9,9 - 二烷基甲醛中間體的合成與9,9 - 二 - 十二烷基芴-2 - 甲醛相同,除了所用的的1 - 烷基溴化物不同。純化后,無(wú)需鑒定便可使用。 9,10 - 雙[(9,9 - 二 - 十二烷基芴-2 - 基)乙烯基]蒽(FLAC12)。 9,9 - 二 - 十二烷基芴-2 - 甲醛(0.167克,0.46毫摩爾)和9,10 - 雙(二乙基磷酰基)蒽(0.10克,0.21毫摩爾)溶解在20mL無(wú)水THF中。加入叔丁醇鉀(0.19克,1.67毫摩爾)后將得到的懸浮液在室溫下攪拌5小時(shí)。將甲醇溶液中加入到混合物中,將所得固體通過(guò)過(guò)濾收集。將粗產(chǎn)物用硅膠柱層析法純化(石油醚/二氯甲烷=4:1,體積/體積)。從氯仿 - 甲醇中重結(jié)晶后,得到黃綠色固體(0.19克,75%產(chǎn)率)。 |
