A nonsulfur probe based on a 1,8-naphthalimide and alkyne conjugate for the ratiometric fluorescent sensing for Hg(2+) and Au(3+) through the tuning of pH in different aqueous solutions is described. This work provides a novel reaction-based approach for selective recognition of these two ions with significant change of fluorescence color and constitutes the first ratiometric case for Au(3+).
一种基于 1,8-萘酰亚胺和炔烃共轭物的无硫探针，通过在不同水溶液中调节 pH 值，实现了对 Hg(2+)和 Au(3+)的比率荧光传感。这项工作为这两种离子的选择性识别提供了一种新的基于反应的方法，荧光颜色有显著变化，并构成了首例 Au(3+)的比率荧光案例。
