A novel colorimetric and off-on fluorescent chemosensor 2 was designed and synthesized, which showed reversible and highly selective and sensitive recognition toward Cr(3+) over other examined metal ions in aqueous solution. Upon addition of Cr(3+), the solution of chemosensor 2 resulted in a color change from colorless to obvious pink color, these significant changes in color could be used for naked-eye detection. Chemosensor 2 exhibited a stable response for Cr(3+) in the range 0-10 μM with a detection limit of 1 ppm. Furthermore, fluorescence imaging experiments of Cr(3+) ions in living MGC803 cells demonstrated its value of practical applications in biological systems.
设计并合成了一种新型比色和荧光化学传感器 2，该传感器在水溶液中对 Cr(3+)具有可逆的、高度选择性和灵敏的识别能力，优于其他检测的金属离子。向化学传感器 2 中加入 Cr(3+)后，溶液的颜色从无色变为明显的粉红色，这些明显的颜色变化可用于肉眼检测。化学传感器 2 在 0-10 μM 范围内对 Cr(3+)表现出稳定的响应，检测限为 1 ppm。此外，在活的 MGC803 细胞中 Cr(3+)离子的荧光成像实验证明了其在生物体系中实际应用的价值。
