通过点击反应合成了一个以苯为中心含蒽荧光团的三足三唑受体分子1.在CH3CN-H2O(V:V=9:1)溶液中,受体分子1对汞离子表现出很好的荧光淬灭响应.其荧光淬灭率为75%,对汞离子的检测极限为6.1×10-6 mol/L.1H NMR滴定表明受体分子中三唑环中的三个N原子与中心离子参与了配位.

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.
