Abstract

On the basis of fluorescence resonance energy transfer (FRET) from benzimidazole to a rhodamine moiety, a rhodamine–benzimidazole conjugate (RBC) ratiometric fluorescent probe has been designed and synthesized. The RBC selectively binds to Cu²⁺, showing visually observable changes in absorption and emission behavior, and demonstrates an effective intracellular Cu²⁺ imaging ability, allowing it to function as a cytoplasm marker.
