摘要
荧光检测作为检测领域中的一项重要分支,由于其灵敏度高、选择性好和响应速度快等优点,引起了广泛的关注。聚集诱导发光(AIE)效应作为一种与聚集导致发光淬灭(ACQ)截然相反的荧光效应,经历了20年的发展后,AIE已经成为荧光材料的重要组成部分。AIE分子在稀溶液状态下不发光或是发光微弱,而在聚集态下或是固态下具有较高的荧光量子产率、独特的光物理性质,使得AIE分子被广泛应用到各个领域,在荧光检测领域表现突出。目前基于AIE分子设计的荧光检测器在微量检测领域展现出了绝对的优势,能够实现对靶标物质的高灵敏、高选择性的定性和定量分析检测。本文简述了近几年来AIE分子在荧光检测毒性物质方面的应用,如毒性离子、分子、病原体等,并对目前存在的问题和应用前景进行了总结和展望。
As an important branch in the field of detection,fluorescence probe has attracted extensive attention due to its high sensitivity,good selectivity,and fast response.The aggregation-induced luminescence(AIE)effect is exactly opposite to the aggregation-caused quenching(ACQ)effect.After 20 years developing,AIE materials has become an important part of fluorescent materials.AIE molecules is a kind of non-or weakly emissive luminogens in dilute solutions while induced to emit intensely upon aggregation or in solid state.Nowadays,AIE molecules have been widely used in various fields due to their unique photophysical properties,especially in the field of fluorescence detection,which has become a research hotspot.The fluorescence detector based on AIE molecule has shown absolute advantages in the field of micro detection,which can realize the qualitative and quantitative detection of the target substance with high sensitivity and selectivity.In this paper,the application of AIE molecule in fluorescence detection of poisonous substance in recent years is reviewed,such as ions,molecules,pathogens.Finally,the existing problems are summarized and the application prospects are prospected.
