合成并表征了一种新的含萘大环三唑类化合物（1）及其无环对照化合物（2）。在乙腈和乙腈水溶液中，1和2对Hg ~（2+）表现出较好的荧光传感能力，其中1由于其大环效应表现出更好的灵敏度和选择性。1H-1 NMR滴定和密度泛函理论计算结果表明，1和2中三唑的N原子和醚基的O原子参与了与Hg ~（2+）的络合作用。(C)2014爱思唯尔有限公司版权所有。
A new naphthalene- containing macrocyclic triazole (1) and its acyclic compared compound (2) have been synthesized and characterized. In acetonitrile and acetonitrile aqueous solutions, 1 and 2 showed good fluorescence sensing ability to Hg2+ over other metal ions, with 1 exhibiting better sensitivity and selectivity than 2 owing to its macrocyclic effect. H-1 NMR titrations and DFT calculation results showed that the N atoms of triazole and O atoms of the ether groups in 1 and 2 participate in binding during complexation with Hg2+.
