crystal structure and non covalent interactions have been incorporated. To achieve the on-site application of TPOD we have performed an experiment in soil sample to detect trace amount of DCP. Moreover the probe can be useful in cellular imaging of DCP containing bio-samples. Thus the probe TPOD is an auspicious, instant and on site monitoring ratiometric fluorescent probe for selective DCP detection in

site for the selective “on–off” fluorescence detection of lethal phosgene with the dimer formation of DPBO through carbonate linkage generated from phosgene. The probe DPBO also exhibits notable spectrofluorometric response in different solvents, as demonstrated by SEM analysis. The detection limit of the probe DPBO towards phosgene was calculated as 21.53 μM, with a fast reaction response time within
开发了一种荧光探针,4-(二苯氨基)-苯甲醛肟 ( DPBO ),包含 4-(二苯氨基) 苯甲醛作为荧光团和羟胺,其中生成的肟基团导致形成选择性识别位点。通过光气产生的碳酸酯键形成DPBO二聚体,对致命光气进行“开-关”荧光检测。SEM 分析证明,探针DPBO在不同溶剂中也表现出显着的荧光光谱响应。计算得出探针DPBO对光气的检测限为 21.53 μM,反应响应时间在 30 s 内,通过估计为 1.03 × 的Stern-Volmer 猝灭常数 ( K SV )测量了光气对DPBO的荧光猝灭效率。 10 4 M -1。通过各种光谱技术,如紫外-可见光、发射光谱、质谱和计算研究,确认了传感机制。在实际应用中,传感器DPBO可用于家用漂白剂、土壤分析和试纸法中光气的检测。
