[求助] 求各位帮帮忙翻个句子,谢谢

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.
学渣啊

我们现在报告,这些十字形的同系物不仅是有效的PFC材料,而且其热回收基态的温度可有效地通过改变N-烷基的长度进行调节。
FCn的合成和结构见图1。合成FCn的一般路线从2,6-双(二乙氧基磷酰基甲基)-9,10-二溴蒽(1)开始。中间体1首先与苯乙烯进行Heck偶联,得到中间体2。中间体2与含不同长度烷基链的4-二烷基氨基苯甲醛进行Wittig–Horner反应,得到预期的十字形FCn,经硅胶柱层析纯化后,产率和纯度都很好。
