A simple and easily synthesized colorimetric and fluorescent chemosensor 1, based on aromatic OH and imine moieties as a binding and anthracene as signaling unit, has been synthesized in a one-step procedure. The chemosensor 1 is developed as a dual chemosensor for detection of Hg and Al ions in CHOH, which exhibited a color change from light yellow to dark yellow with Hg ions, enabling 1 a suitable "bare eye" indicator for Hg ions. On the other hand, fluorescent enhancement with blue shift along with brilliant cyan fluorescence was observed upon binding with Al ions. A possible sensing mechanism has been proposed by means of Job's plot and H NMR titration.
一种基于芳香族羟基和亚胺部分作为结合基团、蒽作为信号单元的简单且易于合成的比色和荧光化学传感器1已通过一步法合成。化学传感器1被开发为一种用于检测CHOH中汞离子和铝离子的双功能化学传感器，它与汞离子反应时颜色从浅黄色变为深黄色，使1成为一种适用于汞离子检测的“肉眼”指示剂。另一方面，与铝离子结合时观察到荧光增强并伴有蓝移以及明亮的青色荧光。通过Job曲线和1H NMR滴定提出了一种可能的传感机制。
