A new sulfide-selective chemosignaling system was devised based on a Cu2+ complex of fluorescein derivative having a dipicolylamine (DPA) binding site; the fluorescein–DPA conjugate 1, in the presence of Cu2+ ions, revealed a selective turn-on type signaling behavior toward sulfide ions with a detection limit of 420 nM in 100% aqueous solution.
基于具有二吡啶胺(DPA)结合位点的荧光素衍生物的 Cu2+ 复合物,设计了一种新的硫化物选择性化学信号系统;荧光素-DPA 缀合物 1 在存在 Cu2+ 离子的情况下,显示出针对硫离子的选择性开启型信号传导行为,在 100% 水溶液中的检测限为 420 nM。
