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.
