Thewater-soluble CP was conjugatedwith a rhodamine spirolactam for the first time to develop a new FRET-based ratiometric fluorescence sensing platform(CP 1) for intracellular metal-ion probing. CP 1 exhibits excellent water-solubility with twowell-resolved emission peaks, which benefit ratiometric intracellular imaging applications.
