摘要：
A rhodamine-benzimidazole based chemosensor was designed and prepared for Fe3+ via opening of the spiro-ring to give fluorescent and colored species. L exhibited high selectivity and excellent sensitivity in both absorbance and fluorescence detection of Fe3+ in aqueous solution with comparatively wide pH range (5.8–7.4). The detection limit of this newly developed probe was shown to be up to 2.74 μM. The reversibility establishes the potential of both probes as chemosensors for Fe3+ detection. Fluorescence imaging experiments of Fe3+ in living MGC803 cells demonstrated its value of practical applications in biological systems.
