Abstract

A simple pyrene-linked thiourea 1 has been synthesized and shown to act as a fluorescent and visual sensor for the detection of Cusup2+/sup and Hgsup2+/sup ions. The sensor showed effective detection of Cusup2+/sup and Hgsup2+/sup at a low detection limit. Receptor 1 has been successfully applied in the fluorescence imaging of Cusup2+/sup and Hgsup2+/sup ions in living cells. Receptor 1 also selectively detects picric acid via both color change and fluorescence change.
