We present a simple way to build up well-controlled coacervate-core dendrimicelles by assembly of anionic PAMAM dendrimers with a cationic-neutral diblock copolymer. Upon increasing pH, the formation of micellar structures shows constant size but the number of dendrimer molecules incorporated in one micelle decreases, following the charge stoichiometry formation rules; concomitantly, the salt stability increases. This study shows the straightforward tuning of macromolecular core-units and related micelle properties.
我们提出了一种通过将阴离子型聚酰胺-胺（PAMAM）树枝状大分子与阳离子-中性二嵌段共聚物组装来构建可控性良好的凝聚核树枝状胶束的简单方法。随着pH值升高，胶束结构的形成显示出尺寸恒定，但一个胶束中所含树枝状大分子分子的数量会根据电荷化学计量形成规则而减少；与此同时，盐稳定性增加。这项研究展示了对大分子核心单元及相关胶束性质的直接调控。
