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 Hg 2+ , Cu 2+ , and Fe 3+ separately. Furthermore, this “turn‐on”‐type fluorescent sensor, upon the addition of Hg 2+ 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.
