文摘

A simple structured Hg2+-selective fluorescent sensor based on an ESIPT dye was developed. Probe showed marked Hg2+-selective signaling via dithiane-to-aldehyde conversion. Interfering response from Cu2+ was removed using citrate buffer as a masking agent. Signaling of Hg2+ in simulated wastewater by readily-usable smartphone was possible.
