A novel fluorescent Hg2+ chemosensor based on dithia-dioxa-monoaza crown ether Was synthesized in four steps from inexpensive starting materials. This new sensor exhibited very strong fluorescence response to Hg2+ (F-Hg(2+)/F-free > 130) and it was highly selective to Hg2+ over the other metal ions by more than 45-fold.
