[求助] 求大神帮忙翻译一小段,真的自己不会,谢谢!!!

For example, most 9,10-bis(arylvinyl)anthracene derivatives exhibit unique aggregation-induced emission (AIE) and PFC behaviour related to the strongly twisted backbone conformations.8d,10c,11,25–30 Contrarily, planar 2,6-bis(arylvinyl)- anthracene derivatives show aggregation-quenched emission and non-PFC behaviour. Therefore, it is very interesting to know whether the center-crossed chromophores integrated by 2,6- and 9,10-bis(arylvinyl)anthracenes are AIE- and PFC-active since
2-D cross-conjugated cruciforms have many unique and interesting optical and optoelectronic properties.31 To the best of ourknowledge, there are no reports on the construction of cruciforms with AIE and/or PFC behaviour at present, and organic materials exhibiting chain length-dependent PFC behaviour are also scarce, although a number of organic fluorophores with chain length-dependent solid-state uorescence have been reported in the past few years.7,11a,25,30,32,33 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 Nalkyllength.
学渣啊

例如,大多数9,10-双(芳乙烯基)蒽衍生物表现出独特的聚集-诱导发光(AIE),并且PFC行为与强烈扭曲的骨架构象有关。【8d,10c,11,25 – 30】相反,平面的2,6-双(芳乙烯基)-蒽衍生物显示聚集-猝灭发光和非PFC行为。因此,有意思的是(非常有趣的是)是否知道由2,6 -双(芳乙烯基)蒽和9,10-双(芳乙烯基)蒽整(组)合的中心(央)-交叉生色团是AIE活化(性)和PFC活化(性),因为二维交叉-共轭十字形(结构)具有许多独特而有趣的光学和光电特性。【31】据我们所知,目前没有构筑含AIE和/或PFC的行为的十字形(结构)的报道,而有机材料表现出链长-依赖的PFC行为也缺乏(研究),尽管在过去的几年里已报道了一些具有链长-依赖的有机荧光体的固态荧光。【7,11a,25,30,32,33】在本工作(文)中,我们设计和合成了一系列2,6-双(对-二烷基氨苯乙烯基) 9,10-二苯乙烯基蒽(FCn,方案1),重点考察PFC行为和烷基链长的影响。
