New colorimetric rhodamine–helicene “OFF–ON” fluorescence sensor based on FRET for quantitative and qualitative Hg2+ determination A novel fluorescent sensor designated as DGM was synthesized by integrating rhodamine 6G with a [5]helicene derivative that served as the binding scaffold and tris(2-aminoethyl)amine as the linking agent. The DGM sensor exhibited a “turn-on” fluorescence response specific to Hg2+, which had a substantial Stokes shift of 176 nm and a detection limit of 21 ppb.
