Phosgene and its substitutes (diphosgene and triphosgene) are widely utilized as chemical industrial materials and chemical warfare agents and pose a threat to public health and environmental safety due to their extreme toxicity. Research efforts have been directed to develop selective and sensitive detection methods for phosgene and its substitutes. In this paper, we have prepared two BODIPY‐based
光气及其替代品(双光气和三光气)被广泛用作化学工业原料和化学战剂,并且由于其极高的毒性而对公共健康和环境安全构成威胁。已经进行了研究努力以开发用于光气及其替代物的选择性和灵敏的检测方法。在本文中,我们已经制备了两种基于BODIPY-荧光探针,ö -Pah和ø -Pha,这两种异构体具有不同的活性位点,邻-aminohydroxy(3',4'或4',3')在的苯基内消旋位置,并比较其对三光气的传感性能。带有o-(4′-氨基-3'-羟基),o的探针‐Pha在o-(3′-氨基‐4′-羟基),o - Pah上表现出更好的感测性能,例如较低的检出限(LOD)(0.34 n m vs. 1.2 n m),并且响应速度更快(10 s和200 s)。此外,根据上述比较研究,通过扩展o - Pha的3,5-共轭,构建了红色荧光探针o - Phae。o- Phae探针显示快速响应(60 s),对三光气的高灵敏度(LOD
