摘要：

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.
