An aqueous fluorescent probe, 1, was developed for the rapid detection of Hg2+ with high sensitivity and excellent selectivity. Upon the addition of Hg2+ in pure aqueous media, the Hg2+-mediated hydrolysis of vinyl ether and subsequent cyclization reactions converted probe 1 into the corresponding iminocoumarin dye, which is strongly fluorescent when excited. The application of this probe for the detection of intracellular Hg2+ was successfully demonstrated in living cells. Copyright © 2015 John Wiley & Sons, Ltd.
开发了一种水性荧光探针 1,用于快速检测 Hg2+,具有高灵敏度和出色的选择性。在纯水介质中添加 Hg2+ 后,Hg2+ 介导的乙烯基醚水解和随后的环化反应将探针 1 转化为相应的亚氨基香豆素染料,该染料在激发时发出强烈的荧光。该探针在活细胞中成功检测细胞内 Hg2+。版权所有 © 2015 约翰·威利父子有限公司
