Abstract:	Eu(III) complexes, Eu(L1)₃(H₂O)] (1) and Eu₂(L2)₆(H₂O)₂] (2) have been prepared and structurally characterized. They are highly selective and sensitive chemosensors for Hg²⁺. These Eu-containing materials show fluorescent enhancement only for Hg²⁺. The complexation of other metal ions leads to fluorescence quenching or no response.
