摘要

光气是一种有毒的窒息性气体，对人类健康构成重大威胁。本研究将聚集体致发射四苯基乙烯（TPE）发光基团与罗丹明肼结合，合成了一种用于光气检测的比例荧光探针。该探针具有旋内酰胺开环特性和与光气的亲核反应，对光气具有独特而敏感的响应。值得注意的是，该探针在比率光气检测中表现出103 nm的Stokes位移增强。此外，开发了365 nm手持式紫外灯下气体光气检测试纸。这些分子的设计和合成对环境健康和公共安全有重要贡献。

An AIEgen-based Fluorescence Probe for Ratiometric Detection of Phosgene in Solution and Gas

Phosgene, a toxic and asphyxiating gas, poses a significant threat to human health. In this study, a ratiometric fluorescence probe for phosgene detection was synthesized based on the combination of aggregation-induced emission tetraphenylethylene (TPE) luminophore and rhodamine hydrazide. The probe exhibits a unique and sensitive response to phosgene based on its spirolactam ring-opening property and nucleophilic reaction with phosgene. Notably, the probe exhibits a large enhanced Stokes shift of 103 nm for ratiometric phosgene detection. Additionally, test strips were developed for the detection of gas phosgene under 365 nm hand-held UV lamps. The design and synthesis of these molecules are significantly contribute to environmental health and public safety.
