Polythiourea, as a kind of seductive material, has been widely applied in various fields. However, the design strategy of polythiourea remains a strong challenge mainly owing to synthesis process is cumbersome and noble metals participate in the reaction. In this report, a new synthetic method is presented to construct poly (siloxane-thioureas) (PTUs) via a simple and economic “one-pot” method. The optical properties of PTUs are mainly investigated by the ultraviolet absorption spectrum and fluorescence spectrum. Noteworthly, PTUs display ultrafast response rate to Cr6+. In addition, PTUs also possess excellent photostability and biocompatibility. A paper sensor based on PTUs is also prepared by visual fluorescence change to achieve the purpose of detection of Cr6+. Herein, it is desired that, as a new type of polythiourea material, PTUs could extend the applications in the bioimaging field.

用于超快检测 Cr6+ 的硫脲桥聚聚硅氧烷及其应用
聚硫脲作为一种诱人的物质，已被广泛应用于各个领域。然而，聚硫脲的设计策略仍然是一个很大的挑战，主要是由于合成过程繁琐且贵金属参与反应。在本报告中，提出了一种通过简单经济的“一锅法”构建聚（硅氧烷-硫脲）（PTU）的新合成方法。PTUs的光学性质主要通过紫外吸收光谱和荧光光谱来研究。值得注意的是，PTU 对 Cr 6+显示出超快的响应速度。此外，PTU 还具有优异的光稳定性和生物相容性。还通过视觉荧光变化制备了一种基于PTUs的纸传感器，以达到检测Cr 6+的目的. 在此，希望作为一种新型聚硫脲材料，PTUs 能够扩展在生物成像领域的应用。
