摘　　要：近几年来,由有机溶剂中微量水引起的工厂、实验室爆炸事件频频发生,引起了社会的极大关注,亟须一种便捷的方法对有机溶剂中的水含量进行测定。作为新兴发展的分析工具,荧光探针具有灵敏度高、选择性好、毒性小、实时可视化监测等优点,在化学化工、食品、环境等领域均有应用。该文综述了近5年水诱导质子化型荧光探针、水诱导金属络合物解离型荧光探针、水参与的化学反应型荧光探针、水诱导形成氢键型荧光探针、水诱导光致电子转移关闭型荧光探针、水诱导分子内电荷转移/扭曲分子内电荷转移型荧光探针、水诱导荧光聚集诱导增强型荧光探针识别水分子的机理;总结了不同机理荧光探针灵敏度和检测限的差异,比较了不同机理荧光探针之间性能的差异以及适用范围;介绍了不同机理荧光探针检测有机溶剂中水含量的优缺点及其应用;最后,对荧光探针在检测有机溶剂水含量的前景进行了展望。In recent years,frequent factory and laboratory explosions caused by trace water in organic solvents have aroused great social concern,which makes the development of a convenient method for water content assessment in organic solvents is of urgent need.As an emerging analytic tool,organic fluorescent probes offer high sensitivity,good selectivity,low toxicity,real-time visual monitoring and are commonly used in the fields of chemical engineering,food,environment,and so on.In this review,water recognition mechanisms of water induction type fluorescent probes,water induced metal complex dissociation type fluorescent probes,water-involved chemical reaction type fluorescent probes,water induced to form hydrogen bond type fluorescent probes,water induced photo-induced electron transfer turn off type fluorescent probes,water induced intramolecular charge transfer/twisted intramolecular charge transfer type fluorescent probes and water induced aggregation induced emission enhancement type fluorescent probes developed in recent five years were summarized.The differences in sensitivity,detection limits,properties and application ranges of fluorescent probes with different mechanisms were then analyzed and compared,followed by discussions on the advantages,disadvantages and applications of fluorescence probes with different mechanisms for water content measurement in organic solvents.Finally,the future development directions of fluorescence probe for water detection in organic solvents was prospected.
