铀的开采、提炼和乏燃料后处理大多在酸性和高含水率的环境中进行。但目前能满足这一要求的荧光探针较少。为此，设计和合成在此条件下检测铀的荧光传感器是一个迫切需要解决的问题。设计并制备了一种新型的三苯胺荧光传感器（USC-001），用于酸性、高含水率环境和生物样品中铀酰离子的检测。即使其他金属离子的浓度比铀酰离子高5倍，该探针对UO_（22+）仍具有良好的选择性。此外，大量的辅助模拟计算和实验不仅揭示了含水率影响荧光光谱变化的机理，而且提出了USC-001识别UO 22+的机理和配位模式。此外，USC-001已成功用于检测实际水样和生物细胞中的铀酰离子。
Uranium mining, refining and spent fuel reprocessing are mostly carried out in an acidity and high water ratio environment. But there are currently fewer fluorescent probes that can meet this requirement. For this purpose, it is a urgent problem to design and synthesis fluorescent sensor for detection of uranium in these conditions. A novel triphenylamine-based fluorescent sensor (USC-001) has been design and prepared for the detection of uranyl ions in acidic and high water ratio environments and biologic samples. And even though the concentration of other metal ions is 5 times higher than that of uranyl ions, the probe is still have good selectivity to UO22+. In addition, a large number of auxiliary simulation calculations and experiment not only reveal the mechanism of the influence of water ratio on the change of the fluorescence spectrum, but also propose the mechanism and coordination mode of USC-001 for identifying UO22+. Furthermore, USC-001 has been successfully used to detect uranyl ions in actual water samples and biological cells.
