摘要：Phosgene, a highly toxic chemical warfare agent and industrial hazard, poses significant environmental and health risks, necessitating the development of rapid and reliable detection methods. Herein, we present a novel near infrared II (NIR-II) fluorescent probe based on silicon rhodamine and an o phenylenediamine-responsive group for the sensitive and selective detection of phosgene. In the presence of phosgene, it generates a distinct color change and lights up NIR-II (900 nm) emission, enabling both naked-eye visualization and fluorescence in vivo analysis. The probe shows rapid exceptional selectivity for phosgene and achieves rapid detection in solutions, gases, and soils. Notably, we successfully utilize this probe for in vivo imaging in Arabidopsis thaliana , enabling high signal-to-noise ratio real-time monitoring of phosgene within plant systems with minimal interference from autofluorescence. This work advances the design of reaction-based NIR-II probes for hazardous chemical monitoring, combining simple operation, high sensitivity, and broad applicability, thereby contributing to environmental safety and sustainability.
