Two-Channel Responsive Fluorescent Probe Of Meso Carboxylate Of Bodipy With Aie Characteristics For Fast Detection Of Palladium

The wide use of palladium species may cause palladium pollution in medicine, food and water, which raises rislcs on environment and health due to the latent hazard of palladium species. In this work, two BODIPY-based fluorescent probes (BDP-COOen and BDP-COOyn) for the detection of palladium have been developed. Both probes displayed strong AIE fluorescence and exhibited selective response to Pd-0 in aqueous buffer. Notably, BDP-COOen showed a favorable two-channel responsive manner as well as preferred reaction kinetics (< 6 min). Furthermore, the probe BDP-COOen was successfully applied for two channel fluorescence imaging of intracellular Pd-0.
