The wide use of palladium species may cause palladium pollution in medicine, food and water, which raises risks 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 Pd⁰ 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 Pd⁰.

钯物种的广泛使用可能会造成药物，食品和水中的钯污染，由于钯物种的潜在危害，这会增加对环境和健康的风险。在这项工作中，已经开发了两种用于检测钯的基于BODIPY的荧光探针（BDP-COOen和BDP-COOyn）。两种探针均显示强AIE荧光，并在水性缓冲液中显示出对Pd ^0的选择性响应。值得注意的是，BDP-COOen显示了有利的两通道响应方式以及优选的反应动力学（<6分钟）。此外，探针BDP-COOen已成功应用于细胞内Pd ^0的两通道荧光成像。
