We now report that these cruciform homologues are not only effective PFC materials, but also that their heatrecovering temperature of ground states can be effectively tuned by changing the N-alkyl lengths. The synthesis and structure of FCn is depicted in Scheme 1. The general route to FCn started from 2,6-bis(diethylphosphoryl-methyl)-9,10-dibromoanthracene (1). Intermediate 1. was first subjected to a Heck coupling with styrene to afford the intermediate 2. TheWittig–Horner reaction of 2 and each 4-dialkylaminobenzaldehyde with different lengths of alkyl chain gave the desirable cruciforms FCn in good yields and purity after purification by column chromatography on silica gel. |

我們現(xiàn)在報(bào)告,這些十字形的同系物不僅是有效的PFC材料,而且其熱回收基態(tài)的溫度可有效地通過改變N-烷基的長度進(jìn)行調(diào)節(jié)。 FCn的合成和結(jié)構(gòu)見圖1。合成FCn的一般路線從2,6-雙(二乙氧基磷酰基甲基)-9,10-二溴蒽(1)開始。中間體1首先與苯乙烯進(jìn)行Heck偶聯(lián),得到中間體2。中間體2與含不同長度烷基鏈的4-二烷基氨基苯甲醛進(jìn)行Wittig–Horner反應(yīng),得到預(yù)期的十字形FCn,經(jīng)硅膠柱層析純化后,產(chǎn)率和純度都很好。 |
