Received Date: 24 February 2007

Fund Project: This research was supported by the NNSFC (No.20332020,20472079).

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_Hg²⁺/F_free >130) and it was highly selective to Hg²⁺ over the other metal ions by more than 45-fold.
