摘要
A novel fluorescent Hg^2+ 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 Hg^2+ (FHg^2+/Ffree 〉 130) and it was highly selective to Hg^2+ over the other metal ions by more than 45-fold.
