摘　　要：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 chemodosimetershave 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 werereviewed 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.
