荧光检测相对于放射性核素检测是一种高灵敏度、低成本、操作方便的化学检测技术,可以用于检测多种化学物质。介绍了荧光化学传感器和化学计量型荧光探针的基本原理。阐明了通过“点击”化学(Cu(I)催化下炔基与叠氮形成稳定的1,2,3-3氮唑化合物)合成荧光化学传感器和化学计量型荧光探针的应用,主要从3个方面展开,包括阴离子识别,阳离子识别以及阴、阳离子对的识别。用于阳离子识别的荧光基团重点介绍了氟化硼二吡咯(BODIPY)、苯并噻二唑和香豆素。

Fluorescence detection is highly sensitive, and avoids the expense and difficulties of handling radioac?tive tracers for most chemical measurements. The definition and principle of chemosensors and chemodosimeters have been introduced. The application of chemosensors and chemodosimeters which were synthesized by Cu(I)-cat?alyzed Huisgen 1,3-dipolar cycloaddition of azides and terminal alkynes (CuAAC) reaction for ion recognition were reviewed from three parts: cation recognition, anion recognition and combined anion and cation recognition by re?cently reported examples. The fluorophores for cation detection were focused on 4,4-difluoro-4-bora-3a,4a-dia?za-s-indacene (BODIPY), benzothiadiazole and coumarin.
