A simple fluorescent probe NHQ based on quinoline was successfully prepared via one-step synthesis. The probe NHQ exhibited "turn-on" fluorescence and excellent selectivity toward Cd(2+) in different buffer solutions such as Tris-HCl buffer solution, HEPES buffer solution, and PBS buffer solution, and even in water. Moreover, the binding model of NHQ with Cd(2+) was definitely confirmed by the single crystal X-ray diffraction studies of the complex.
通过一步合成法成功制备了一种基于喹啉的简单荧光探针NHQ。该探针NHQ在不同缓冲溶液（如Tris-HCl缓冲溶液、HEPES缓冲溶液和PBS缓冲溶液）甚至水中均表现出“开启”荧光以及对Cd(2+)的优异选择性。此外，通过配合物的单晶X射线衍射研究明确证实了NHQ与Cd(2+)的结合模式。
