The synthesis and photophysical properties of a novel fluorescent sensor are described. The phosphorus−selenium moiety allowed a selective mercury salt complexation, followed by the formation of phosphane oxide, which leads to a turn-on of the fluorescence. The sensibility and selectivity toward mercury cations were evaluated (0.18 ppb) and found to be in complete adequation with the targeted level
描述了新型荧光传感器的合成和光物理性质。磷-硒部分允许选择性的汞盐络合,随后形成氧化膦,这导致荧光的开启。对汞阳离子的敏感性和选择性进行了评估(0.18 ppb),发现与世界卫生组织的目标水平完全吻合,这使该染料成为汞阳离子的有效剂量计。
