Real-time sensing of Chemical Warfare Agents (CWAs) is today a crucial topic to prevent the lethal effects of a terroristic chemical attack. For this reason, the development of efficient, selective, sensitive and reversible sensoristic devices, able to detect by optical response ppm levels of these compounds, is strongly required. Here, the synthesis of a new fluorescent sensor based on a salen-uranyl scaffold, functionalized with two bodipy moieties, and its application for the detection of sub-ppm levels of CWAs is reported. Detection properties were evaluated by fluorescence measurements and selectivity tests demonstrated the strong affinity for CWAs.

今天，对化学战剂（CWA）进行实时传感已成为防止恐怖化学袭击的致命影响的关键主题。因此，迫切需要开发能够通过光学响应检测这些化合物的ppm水平的高效，选择性，灵敏和可逆的传感设备。在此，报道了基于具有两个bodipy部分功能的salen-uranyl支架的新型荧光传感器的合成，及其在检测亚ppm水平的CWAs中的应用。通过荧光测量评估检测性能，选择性测试证明对CWA具有很强的亲和力。
