Phosgene is a highly toxic substance that has become a serious potential threat to public health safety. A colorimetric and ratiometric fluorescence probe 1 for phosgene has been developed based on an ESIPT process. Both the visible colorimetric change from colorless to yellow and the fluorescent color change from blue to green (under 365 nm hand-held UV lamp) can be easily observed by the naked eye. Probe 1 has a high sensitivity and selectivity for phosgene in solutions and the gas phase. The mechanism for sensing by 1 was investigated by using high-resolution mass spectrometry and 1H NMR and 13C NMR spectroscopies.

基于ESIPT的荧光探针，用于溶液和气相中光气的比色，比率和选择性检测
光气是一种剧毒物质，已经成为严重威胁公共健康的潜在威胁。基于ESIPT方法，已开发了用于光气的比色和比例荧光探针1。可见色度从无色变为黄色，荧光色从蓝色变为绿色（在365 nm手持紫外线灯下），都可以用肉眼轻松观察到。探针1对溶液和气相中的光气具有很高的灵敏度和选择性。通过使用高分辨率质谱和1 H NMR和13 C NMR光谱研究了1的感应机理。
