Abstrakt: Palladium (Pd) is a significant heavy metal with outstanding catalytic properties, extensively utilized in the pharmaceutical industry and organic chemistry. Due to the detrimental impact of palladium on human health and the environment, there is a pressing need for efficient and convenient analytical techniques. In this context, we have created a simple fluorescent switch-on probe, INXPd, for the selective determination of Pd 0 . The allyl carbonate in INX-Pd could be entirely cleaved by Pd 0 to produce the intermediate INX-OH, resulting in distinct colorimetric and fluorometric alterations. INX-Pd displayed high sensitivity in detecting Pd 0 , with a detection limit of 56 nM, and a fast response time (2.0 min). INX-Pd was successively utilized to determine Pd 0 in drugs, water, soil, and various foodstuff samples as well as smartphone and test strips. Moreover, cell imaging experiments demonstrated that INX-Pd is suitable for imaging Pd 0 in living cells.
