[求助] 几句论文求大神翻译成中文,谢谢

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,我们设计并合成了一系列2,6 - 双(对 - 二烷基氨基苯乙烯基)-9,10 - 二苯乙烯基蒽(FCN,方案1),研究着重在PFC性能和N-烷基长度的影响。我们现在报告,这些十字形的同系物不仅是有效的PFC材料,而且可通过改变N-烷基的长度有效地调整其热回复温度。
FCn的合成和结构描述见方案1。合成FCn的一般路线从2,6 - 双(二乙基膦酰基甲基)-9,10 - 二溴蒽开始【1】。中间体1先与苯乙烯进行Heck偶联,得到中间体2。中间体2与具有不同烷基链长度的每一4-二烷基氨基苯甲醛进行Wittig–Horner反应,得到期望的十字形FCn,经硅胶柱层析后得到的良好的产率和纯度。
