A facile AIE fluorescent probe which exhibits a large stokes shift of 202 nm has been successfully developed. The probe can recognize Cd2+ with high selectivity by inhibiting ESIPT process, leading to observably blue-shift and significantly enhanced fluorescence with the colour changed from green to cyan. Excitedly, the recognition of Cd2+ is completely free from the interference of Zn2+ and Cd2+ could be quantitatively detected in aqueous solution with the detection limit of 1.5 × 10−7 M. Moreover, the probe has been successfully applied to detect Cd2+ in real water samples and image Cd2+ in living cells.

一种具有大斯托克斯位移的简便 AIE 荧光探针，用于检测真实水样和活细胞中的 Cd2+
已成功开发出一种简便的 AIE 荧光探针，其具有 202 nm 的大斯托克斯位移。该探针通过抑制 ESIPT 过程可以高选择性地识别 Cd 2+，导致可观察到的蓝移和显着增强的荧光，颜色从绿色变为青色。令人兴奋的是，Cd 2+的识别完全不受Zn 2+的干扰，可以在水溶液中定量检测Cd 2+，检测限为1.5 × 10 -7 M。此外，该探针已成功应用于检测镉2+实际水样和图像镉2+在活细胞中。
