• BODIPY
• Colorimetric recognition
• 'Turn off' fluorescence
• Sequential recognition

A new multifunctional probe made up of boron dipyrromethene (BODIPY) and benzimidazole neighboring phenol was designed and synthesized. This probe displays a colorimetric recognition of Hg2+ and a 'turn off' fluorescent response to Cr3+ at physiological condition. The 'in situ' ensemble of host and Hg2+ shows a selective and ratiometric detection of I- via the formation of three-component ensemble. These systems were further used to detect their corresponding targets in real water sample with acceptable recovery. Compared to the comprehensive report of the single-target responsive chemosensor, these results provided an approach to design the challenging multifunctional probe.
