摘　　要：苯胺是一种使用广泛但具有高毒性的化学原料,对环境安全和人类健康有巨大的潜在威胁。因此,对苯胺的检测具有重要的应用价值。本文设计并合成了一种可对苯胺进行选择性检测的氰基二苯乙烯衍生物(CN-DBE)荧光探针材料。通过光致发光光谱和数值模拟等方法对CN-DBE的聚集诱导发光性质、传感性能和检测机理进行了详细研究。结果表明,基于光诱导电子转移机理,CN-DBE可实现对苯胺的高选择性、定量、快速检测。此外,利用浸渍法制备了相应的CN-DBE试纸,可实现对苯胺的可视化检测,提供了一种廉价且简单的苯胺泄漏检测方法。Aniline sensing is of great societal implications,as aniline is a crucial chemical raw material but with high toxicity,processing with huge impacts on environment safety and human health.Herein,a novel cyanostilbene derivative(CN-DBE)was designed and synthesized as selective fluorescent probe material for aniline detection.Its aggregation-induced emission property,sensing property and detection mechanism were elucidated by photolumines-cence spectra and numerical simulation.The results reveal that CN-DBE possesses high selectivity,quantitative and rapid detection ability to aniline due to the electron transfer mechanism.Moreover,the CN-DBE compound can also enable the fabrication of test strips,which provide a cheap and simple way to detect aniline leakage.
