In the current work, we have designed and synthesized a series of 2,6-bis(p-dialkylaminostyryl)-9,10-distyrylanthracenes (FCn, Scheme 1) to examine emphatically the PFC behaviour and the effect of the Nalkyl length. 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. |

在目前的工作中,我們設(shè)計(jì)并合成了一系列2,6 - 雙(對 - 二烷基氨基苯乙烯基)-9,10 - 二苯乙烯基蒽(FCN,方案1),研究著重在PFC性能和N-烷基長度的影響。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,而且可通過改變N-烷基的長度有效地調(diào)整其熱回復(fù)溫度。 FCn的合成和結(jié)構(gòu)描述見方案1。合成FCn的一般路線從2,6 - 雙(二乙基膦;谆-9,10 - 二溴蒽開始【1】。中間體1先與苯乙烯進(jìn)行Heck偶聯(lián),得到中間體2。中間體2與具有不同烷基鏈長度的每一4-二烷基氨基苯甲醛進(jìn)行Wittig–Horner反應(yīng),得到期望的十字形FCn,經(jīng)硅膠柱層析后得到的良好的產(chǎn)率和純度。 |
