This communication presents a fluorescent chemosensor for detecting Pb(II) and Hg(II) in aqueous solutions. The sensor showed a turn-on response to Pb(II) by an enhancement of emission intensity at 380 nm and to Hg(II) by an enhancement of emission intensities at 380 and 475 nm. We have first characterized a unique function of tryptophan as a ligand as well as a quencher for recognition and fluorescent change by a metal binding event.
本通讯介绍了一种用于检测水溶液中 Pb(II) 和 Hg(II) 的荧光化学传感器。该传感器对 Pb(II) 的响应为 380nm 处发射强度的增强，对 Hg(II) 的响应为 380nm 和 475nm 处发射强度的增强。我们首次描述了色氨酸作为配体以及金属结合事件识别和荧光变化的猝灭剂的独特功能。
