A new selective fluorogenic chemosensor for Hg, which combines a calixarene derivative with a BODIPY core as a fluorescent reporter, is described. The remarkable change in its fluorogenic properties in DMSO and CHCl has been analyzed. A study of its spectral properties on dilution, along with molecular modeling studies, allowed us to explain that this behavior involves the formation of a J-dimer, as well as how the sensing mechanism of Hg proceeds.
描述了一种新型的汞选择性荧光化学传感器,它将杯芳烃衍生物与作为荧光报告基团的BODIPY核心相结合。分析了其在二甲基亚砜(DMSO)和氯仿(CHCl)中荧光性质的显著变化。对其稀释时的光谱性质进行研究,并结合分子模拟研究,使我们能够解释这种行为涉及J-二聚体的形成,以及汞的传感机制是如何进行的。
