Rhodamine‐based reversible fluorescence turn‐on chemosensor appended with ‘N’ and ‘O’ donor atoms as chelating moieties has been synthesized for the selective detection of Fe 3+ ion over other competitive metal ions in aqueous medium. Designed probe indicated color change to pink with lower limit of detection at 1.93×10 −7 M exhibiting high sensitivity toward Fe 3+ ion. Sensing mechanism was established by HRMS and NMR titration studies. The probe was successfully applied for the detection of Fe 3+ ions in live MCF‐7 cells.
