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CH_3CN-H_2O(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 click reaction of anthracene fluorophore-containing triazolium receptor molecule 1 was synthesized by the click reaction. In the solution of CH_3CN-H_2O (V:V = 9: 1), the acceptor molecule 1 showed very strong mercury ion Good fluorescence quenching response with a fluorescence quenching rate of 75% and a mercury ion detection limit of 6.1 × 10 -6 mol / L. 1H NMR titrations indicate that three of the triazole rings in the acceptor molecule N atoms and central ions participate in coordination.
