  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.

  一种基于荧光素-烯丙氧基苯基骨架的钯选择性化学传感器，以及使用该化学传感器检测液体样品中钯离子的方法，其中将液体样品与包括水和化学传感器的溶液接触以形成混合物。测量混合物的紫外可见吸收谱和/或荧光发射谱以确定液体样品中钯离子的存在或不存在，其中化学传感器在溶液中具有315至325 nm的紫外可见吸收峰和380至400 nm的荧光发射峰，在混合物中紫外可见吸收峰向338至342 nm的巴氏红移和/或荧光发射峰向530至550 nm的巴氏红移表明液体样品中存在钯离子。
