摘要：
An easily prepared "turn-on" -type fluorescent chemosensor for mercury based on Rhodamine-B, which exhibits high sensitivity and selectivity over other metal ions in aqueous systems, was obtained. The distinctive wavelengths in the UV/Vis absorption range can sense Hg2+, Cu2+, and Fe3+ separately. Furthermore, this "turn-on" -type fluorescent sensor, upon the addition of Hg2+ over other competitive species, was successfully applied to bioimaging in yeast and HeLa cells. The potential of these types of chemosensors for use in environmental and biological systems is great.
