Abstract
- The eco–environmental toxicity of the rare metal palladium (Pd) has received extensive attention, thereby requiring simple and practical methods for detecting Pd. Herein, a new probe (HPD) based on dicyanoisophorone dye was designed and synthesized for the detection of Pd. HPD provides several advantages for tracking Pd, including near–infrared (NIR) emission (λ ex = 670 nm, λ em = 700 nm), naked–eye recognition, and comprehensive detection of 0/2/4 valence Pd with good selectivity and anti–interference. The reaction–sensing mechanism of HPD for Pd was further studied using density functional theory calculations. HPD was demonstrated to be a promising tool for the detection of Pd in real water samples, as well as the imaging of Pd in living cells and animals. [Display omitted] • A novel intramolecular charge transfer (ICT) based fluorescence probe was developed to detect palladium (Pd). • Near–infrared (NIR) emission and naked–eye detection of Pd are performed. • The detection mechanism of the probe was verified by experiments and calculations. • The probe can detect Pd in real water samples, living cells and animals.
