苯基偶氮甲碱树枝状聚合物,可用作精确的金属纳米粒子的模板,仅在非质子介质中可溶。特定表面活性剂的使用使得它们能够在水溶液中增溶。在稀释条件下,它们形成离散的胶束,其尺寸接近树枝状大分子的尺寸。缩合导致它们聚集;然而,它们保持在均匀溶液中而没有沉淀。此外,每个胶束被很好地分离。胶束中锌卟啉核心的三重激发态是显着稳定的,这表明刚性核壳胶束的形成防止任何外部分子接近核心。
Phenylazomethine dendrimers, which can be used as the template for precise metal nanoparticles, are soluble only in aprotic media. The use of a specific surfactant enabled their solubilization in aqueous solutions. Under dilute condition, they formed discrete micelles with a size close to the that of the dendrimer. Condensation resulted in their aggregation; however, they remained in a homogeneous solution without precipitation. Furthermore, each micelle was well isolated. The triplet-excited state of the zinc porphyrin core in the micelles was significantly stable, suggesting the formation of rigid core-shell micelles preventing any external molecules from approaching to the core.
