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 of the World Health Organization, which makes the dye an efficient dosimeter for mercury cations.
描述了一种新型荧光传感器的合成和光物理性质。磷-硒部分允许选择性地与汞盐络合,然后形成膦氧化物,从而导致荧光的开启。评估了该传感器对汞阳离子的灵敏度和选择性(0.18 ppb),发现其与世界卫生组织的目标水平完全一致,这使得该染料成为汞阳离子的有效剂量计。
