The title paper describes the photophysics of a series of 2-benzylidenemalononitrile (RDC) derivatives, having donor- π – acceptor (D-π-A) architecture in solution, solid state and in hydrosol. Interestingly, it is observed that by tuning the electronic energy levels via changing donor strength, one can play with the emissive properties to the large extent; from non- fluorescent to fluorescent, to aggregation induced dual fluorescence, to aggregation induced enhanced emission (AIEE). The nature of aggregation is studied by Field Emission Scanning Electron Microscope (FESEM). This aggregation induced emission (AIE) in hydrosol is used to develop a thin layer chromatography (TLC) based simple, easy to use technique to identify the trinitrophenol in aqueous solution as well as can distinguish the three positional nitrophenol derivatives.

标题论文描述了在溶液，固态和水溶胶中具有供体-π-受体（D-π-A）结构的一系列2-亚苄基丙二腈（RDC）衍生物的光物理性质。有趣的是，观察到通过改变施主强度来调节电子能级，人们可以在很大程度上发挥发射特性。从非荧光到荧光，再到聚集诱导的双重荧光，再到聚集诱导的增强发射（AIEE）。聚集的性质通过场发射扫描电子显微镜（FESEM）研究。溶胶中的这种聚集诱导发射（AIE）用于开发基于薄层色谱（TLC）的简单易用的技术来鉴定水溶液中的三硝基苯酚以及可以区分三种位置的硝基苯酚衍生物。
