Title
Detection of Hg2+ ion in aqueous media by new fluorometric and colorimetric sensor based on triazole–rhodamine
Abstract

•A novel rhodamine B derivative bearing triazole unit (RHT) were synthesized in two steps.•The prepared RHT was characterized by using spectroscopic techniques.•RHT showed a highly selective and sensitive response as fluorometric and colorimetric towards Hg2+ ion.

A highly efficient and selective rhodamine B sensor bearing triazole unit (RHT) as the metal ion receptor was designed and synthesized. RHT was characterized by 1H NMR, 13C NMR, APT, COSY, FTIR, elemental analysis, and also its binding selectivity toward various metal ions was studied. Fluorescence enhancement by factors 24 times was achieved upon selective interaction with Hg2+ ion over other metal ions in aqueous solutions. Selective fluorescent enhancement of RHT was attributed to ring opening from the spirolactam (nonfluorescent) to ring-opened amide (fluorescent). Also, distinct color changes from colorless to pink provided “naked eye” detection of Hg2+.
