A new anthracene-containing tripodal triazole with 1,3,5-trisubstituted benzene core has been easily synthesized by "click reaction".Among various metal ions,1 shows exclusive fluorescence turn-off sensing of Hg2+ in CH3CN-H2O(V:V=9:1) solution.The quenching ration is about 75%,and the detection limit for Hg2+ is 6.1×10-6 mol/L.The 1H NMR titrations results reveal that the N atoms of the three triazoles of 1 take part in binding with center ion with forming 1:1 1-Zn2+ complex.

Key words: tripodal receptor, triazole, anthracene, mercury ion, fluorescence sensing
