摘要

制备了一种选择性灵敏的显色和荧光双信号响应氟化物传感器(L),该传感器由罗丹明6G荧光团和2,2 ' -联吡啶组成。将汞离子加入到L的CH3CN溶液中后,颜色由无色变为粉红色,表明该传感器可以作为汞离子的灵敏“肉眼”指示器。高发射选择性是由于L- hg2 + 1:2配合物的形成导致L的螺旋循环打开。

Highly Sensitive Fluorescent Probe for Selective Detection of Hg2+
A selective and sensitive chromogenic and fluorogenic dual signal responding fluoride-sensor (L), comprising the well-known rhodamine 6G fluorophore and 2,2′-bipyridine was prepared and spectroscopically characterized. After mercury ion was added to the CH3CN solution of L, a color change from colorless to pink-red, which indicated that the sensor can serve as a sensitive “naked-eye” indicator for mercury ion. The high emission selectivity is due to the formation of L-Hg2+ 1:2 complex leads to spirocycle opening of L.
