摘　　要：全氟辛烷磺酸盐(Perfluorooctane sulfonate,PFOS)是一种持久有机污染物,具有生物毒性、高稳定性、存在范围广的特点,严重威胁人类健康安全。因此,对PFOS的检测具有重要意义。本文通过简单的合成制备了一种四苯基乙烯衍生物(TPE-py)用于检测PFOS。通过核磁共振谱图、荧光光谱以及紫外-可见吸收光谱等方法对其分子结构、光物理性质、检测效果和传感机理进行了研究。实验结果表明,基于静电相互作用和聚集诱导发光性质,TPE-py可实现对PFOS“开启”式的快速定量检测,检测限为0.11μmol/L。Perfluorooctane sulfonate(PFOS)is a persistent organic pollutant,which has the characteristics of biotoxicity,high stability and wide distribution,which is a great threat to human health and safety.Therefore,the detection of PFOS is of great significance.In this paper,a tetraphenylvinyl derivative fluorescent probe(TPE-py)was prepared by simple synthesis for the detection of PFOS.The molecular structure,photophysical property,detection effect and sensing mechanism were studied by means of NMR spectroscopy,fluorescence spectrum and ultravioletvisible absorption spectrum.The results show that TPE-py was successfully prepared and it can detect PFOS quickly and quantitatively based on the properties of electrostatic interaction and aggregation-induced emission by turn-on mode and the detection limit is 0.11μmol/L.
