Extensive use of palladium in many catalysts and catalytic converters causes a high degree of pollution of water and soil resources. Therefore, there is an urgent need to develop rapid and sensitive palladium probes. Herein, a novel "turn-on" near-infrared (NIR) fluorescence and colorimetric probe for Pd has been designed on the basis of the deallylation of the probe, followed by the release of NIR emissive fluorophore through the Tsuji-Trost reaction. The probe can selectively discriminate between the oxidation states of Pd and Pd. Sensing results demonstrates that the probe has excellent selectivity, sensitivity, fast response time, NIR fluorescence, high biocompatibility, and low detection limit for the Pd detection over a series metal ion. The probe has been successfully applied in visualization of residual Pd content from water, soil, drug and living cell samples by fluorescence observation with the naked eye.
钯在许多催化剂和催化转化器中的广泛应用导致了水资源和土壤资源的高度污染。因此，迫切需要开发快速灵敏的钯探针。在此基础上，基于探针的脱保护作用，通过 Tsuji-Trost 反应释放近红外（NIR）发射荧光团，设计了一种新型的“开启”近红外（NIR）荧光和比色钯探针。探针可以选择性地区分钯和钯的氧化态。传感结果表明，该探针对一系列金属离子具有优异的选择性、灵敏度、快速响应时间、NIR 荧光、高生物相容性和低检测限。该探针已成功应用于通过荧光观察肉眼可视化水、土壤、药物和活细胞样品中残留钯含量。
