摘要：We herein report a novel fluorescent probe for Hg2+ based on the deprotection of 1,3-dithiolane, via the covalent assembly principle. Presence of Hg2+ triggers a cascade, which ultimately furnishes the push-pull backbone of a fluorescent dye, rendering a turn-on signal from a zero background and hence high detection sensitivity.
