Abstract
2,2-Dipicolylamine (DPA) based receptors detect Zn(2+) with high fidelity. A fluorescent sensor with thiocarbamate-linked DPA turns it into a highly selective module for Ag(+) with up to ~7-fold enhancement of fluorescence. The sensor exhibits a double ratiometric behavior. It also displays an interesting [Ag(+)] dependent aggregation induced emission.
摘要
2,2-联吡啶-4-甲胺（DPA）基受体具有高保真度检测 Zn(2+) 的能力。一个带有硫代氨基甲酸酯键联 DPA 的荧光传感器将其转化为对 Ag(+) 具有高选择性的模块，荧光增强高达约 7 倍。该传感器表现出双重比率行为。它还显示出有趣的 [Ag(+)] 依赖聚集诱导发射。
