摘要
对于公共安全中存在的安全隐患及时检测和预防有助于保护公民的身体健康和财产安全。荧光检测技术以其优异的选择性、高的灵敏度、快的响应速度引起了广泛的研究。聚集诱导发光(AIE)材料作为一种与聚集导致发光猝灭(ACQ)材料截然相反的新兴有机荧光材料,实现了发光分子在固态或是聚集态下的高荧光量子产率。而独特的AIE特性,使其不必担心由于分子聚集导致的荧光信号的降低或猝灭,同时由于分子聚集程度的增加引起荧光颜色和强度的变化,可以被用来实现对靶标物的定性和定量分析,为荧光分析检测提供了新的思路和方案。目前基于AIE的荧光检测方法及相关技术已经被广泛应用各个领域,其中在公共安全领域的研究表现突出,并取得较高的研究成果。本文分析总结了近几年来AIE分子在公共安全领域中的应用进展,包括爆炸性物质、指纹识别、毒品检测、食品安全等方面,并对目前存在的问题和应用前景进行了总结和展望。
Nowadays,detection and prevention of some hidden dangers existing in public security is of great importance for protection of citizens’health and property.Among many detection methods,fluorescence detection technology exhibits distinct advantages of high sensitivity,good selectivity and fast response etc.,and has been widely applied in diverse sensing areas.Aggregation-induced emission(AIE)materials,as a new type of organic fluorescent materials,which is exactly opposite to the aggregation-caused quenching(ACQ),achieve high fluorescence quantum yield in solid or aggregated state.The AIE molecule exhibits unique characteristics,lower back-ground,higher signal to noise ratio and more outstanding resistance to photobleaching etc.Moreover,it can avoid the decrease or quenching of emission caused by molecular aggregation.Meanwhile,the increase of molecular aggregation leads to the change of fluorescence color and intensity,so it can be used to achieve the qualitative and quantitative analysis of target.At present,AIE-based fluorescent detection methods and the related technologies have been widely applied in various fields,especially for the public security,which has obtained high research achievements.In this paper,the advance of AIE molecules in the field of public security in recent years were analyzed and summarized,including fluorescent sensors for explosive substances,fingerprint identification,drug detection,food safety.Finally,the existing problems and application prospects were summarized and prospected.
