  摘要：

  设计了一种能够感知环境pH变化的双发射光子纳米物体，基于由两亲性嵌段共聚物组装的壳交联胶束，并与pH不敏感的染料交联。这些染料交联剂是具有四官能团的哌嗪分子，带有一组末端脂肪胺基团和一组苯胺胺基团，对纳米物体的聚丙烯酸壳域表现出形态依赖的反应性。苯胺胺基团与纳米物体壳的反应程度被证明会影响催移（蓝移）。496 nm处的荧光强度与560 nm处的荧光强度之比依赖于溶液的pH。我们在此报道了棒状或球形纳米物体的pH敏感双发射光物理特性的观察，其壳域提供了两个不同的平台进行酰胺化反应——通过加入碳二亚胺形成活化酯或预先安装活化酯基团。我们证明物理操作（形态或颗粒尺寸的变化）或化学操作（活化酯安装顺序）的交联反应可以在生理相关的pH范围内使双发射细微调整约60 nm。具有聚（p-羟基苯乙烯）核心的棒状壳交联纳米结构随着pH的增加而蓝移，而具有聚苯乙烯核心和聚乙烯氧化物冠层的球形壳交联纳米结构则随着pH的降低而蓝移。

  Described herein are optical agents, including compositions, preparations and formulations, for monitoring the pH of a fluid. Optical agents described herein include photonic nanostructures and nanoassemblies including supramolecular structures, such as shell cross-linked micelles, that incorporate at least one linking group comprising one or more photoactive moieties that provide functionality as exogenous agents for a range of pH monitoring applications. Optical agents described herein comprise supramolecular structures having linking groups imparting useful optical and structural functionality. In an embodiment, for example, the presence of linking groups function to covalently cross link polymer components to provide a cross-linked shell stabilized supramolecular structure, and also impart useful optical functionality, for example by functioning as a fluorophore.
