Polymer-based fluorescence sensor incorporating thiazole moiety for direct and visual detection of Hg2+ and Ag+

Polymer-based sensor incorporating thiazole ligand moiety exhibited 'turn-off' fluorescence response on both Hg2+ and Ag+. The color change of this polymer solution could be clearly observed by the naked eyes upon the addition of Hg2+ (green to colorless) and Ag+ (green to yellow).
