Chemosensors play important parts in the selective recognition of ions, which is widely applied in various fields of environment, industry and biological sciences. In this work, a chemosensor for multi-metal ions based on rhodamine B derivative was synthesized, which could selectively recognize various metal ions in different solvent system. The addition of Cu2 + caused the color change from colorless to pink in EtOH/H2O (v/v = 1:1) solvent system, which could be quickly identified by the naked eyes with a detection limit of 8.27 × 10? 8 M. In ethanol solution system, the addition of Fe3 + and Zn2 + caused different fluorescence changes with the detection limit of 2.12 × 10? 7 M and 6.64 × 10? 7 M respectively. The binding ratios are 1:1 (1-Cu2 +), 2:1 (1-Fe3 +) and 1:1 (1-Zn2 +), respectively. Meanwhile, the probe 1 was used to detect the trace metal ions in real water samples. Besides, the probe 1 showed sensitive fluorescence signals for Fe3 + in biological cells. The experimental results further verify the application value of the sensor.
