Sensing of gaseous environment pollutants and health hazards is in demand these days and in this regard, lethal phosgene has emerged as a leading entrant. In this contribution, we have successfully developed a facile chemodosimeter (ANO) based on an anthracene fluorophore and oxime recognition site with an interesting mechanism to sense lethal phosgene evolved from bleaching powder, a very popular disinfectant and sanitizer. The ANO probe is highly competent in recognizing deadly phosgene in solution and in the gaseous phase with a detection limit in the nanomolar range (1.52 nM). The sensing mechanism is confirmed by UV-vis, emission spectroscopy, mass spectrometry, and computational studies.
如今，对气态环境污染物和健康危害的检测需求日益增长，在这方面，致命的光气已成为主要的进入者。在本研究中，我们成功地开发了一种基于蒽荧光团和肟识别位点的简便化学传感器（ANO），具有一种有趣的机制，可以检测来自漂白粉（一种非常流行的消毒剂和杀菌剂）的致命光气。ANO 探针在溶液中和气相中都具有很高的识别致命光气的能力，检测限达到纳摩尔范围（1.52 nM）。通过紫外-可见光谱、发射光谱、质谱和计算研究证实了传感机制。
