Abstract
A palladium selective chemosensor based on a fluorescein-allyloxy benzene scaffold and a method of detecting palladium ions in a fluid sample with the chemosensor, whereby the fluid sample is contacted with a solution that includes water and the chemosensor to form a mixture. An ultraviolet visible absorption profile and/or a fluorescence emission profile of the mixture is measured to determine a presence or absence of palladium ions in the fluid sample, wherein the chemosensor has an ultraviolet visible absorption peak at 315 to 325 nm and a fluorescence emissions peak at 380 to 400 nm in the solution, and wherein a bathochromic shift in the ultraviolet visible absorption peak to 338 to 342 nm in the mixture and/or a bathochromic shift in the fluorescence emissions peak to 530 to 550 nm in the mixture indicates the presence of palladium ions in the fluid sample.
