Abstract

A rhodamine-based chemosensors (RF) was designed, and their sensing behavior toward metal ions was investigated by fluorescence spectroscopies. RF showed high selective recognition toward Cr3+ over other examined metal ions in aqueous media. With the optimum condition described, the response was linearly proportional to the concentration of Cr3+ in the range 0–10 μM with a detection limit of 0.023 μM. The proposed method was also applied to intracellular Cr3+ imaging in living cells and determination Cr3+ in tap water, river water.
