ESIPT‐Active Naphthalene‐Based Hydroxyoxime Fluorescent Chemodosimeters for Rapid and Sensitive Phosgene Sensing in Solution and Polymer Films
Abstract
ABSTRACT Choking agents such as phosgene, diphosgene, and chlorine pose serious threats to public health due to their extreme inhalation toxicity. Exposure to these gases can cause severe damage to the respiratory system, leading to acute oxygen deprivation, respiratory failure, and potentially fatal outcomes. In this regard, two hydroxy‐oxime‐based chemodosimetric fluorescent probes, HNOX‐6 and HNOX‐7 , were designed, synthesized, and characterized using 1 H NMR, 1 3 C NMR, FT‐IR spectroscopy, and HRMS methods. Among the two probes, HNOX‐6 exhibits exceptional sensing performance with an ultralow detection limit of 0.042 nM and an ultrafast response time of
