| Synthesis and Spectroscopic Studies of Molecular Fluorescent Probe for Hg2+ Detection Based on Boron Dipyrromethene Fluorophore |

| 摘要: 合成了一种中位-苯甲酸基取代的氟硼二吡咯类染料衍生物(1)并研究了它的金属离子传感性能。在甲醇溶液中，染料1显示出显著的对汞离子具有选择性的“开-关”型亲离子荧光团响应，而对其他一些代表性碱金属、碱土金属、过渡金属及重金属离子等都没有明显的荧光响应；同时染料1在对所检测的金属离子中，通过其溶液颜色的改变对汞离子显示出明显的选择性显色行为，以便实现对汞离子的 “裸眼检测”。 |

| Abstract: A novel boron-dipyrromethene (BDP) derivative 1 with benzoyloxy subunit at meso-position was synthesized and its metal ion sensing properties were investigated. In methanol, dye 1 exhibits pronounced “on-off-type” fluorescence response with high selectivity towards Hg2+ among the representative alkali-, alkaline earth-, transition- and heavy-metal ions, and dye 1 also shows a significant Hg2+ selective chromogenic behavior over the other tested metal ions by changing the color of the solution, which makes possible the “naked-eye detection” of Hg2+. |
