来宾的拓扑选择性封装通常由明确定义的主机专门实现。本文制备了一种以超支化聚乙烯亚胺（PEI）为核、聚苯乙烯（PSs）为壳的高分子反胶束（PEI@PS），并表现出优异的封装和分离能力。研究发现，封装和相转移在动力学上取决于染料的尺寸，从而为染料的分离创造了时间窗口。所有实验结果表明，壳的厚度和密度对客体选择性起着最重要的作用。此外，还发现了高度尺寸选择性的释放。这种大分子反胶束 (PEI@PS) 可在液-液或固-液萃取分离中找到有用的应用，尤其是后者。© 2013 Wiley periodicals, Inc.

Topology-selective encapsulation of a guest is generally exclusively achieved by a well-defined host. In this article, a macromolecular reverse micelle (PEI@PS), with a hyperbranched polyethylenimine (PEI) as core and polystyrenes (PSs) as shell, is prepared and shown with excellent encapsulation and separation abilities. It is found that the encapsulation and phase transfer is kinetically dependent on the size of the dyes, creating a time window for the separation of dyes. All the experimental results show that the thickness and density of shell plays the most important roles in guest selectivity. In addition, highly size-selective release is also found. This macromolecular reverse micelle (PEI@PS) can find useful applications in the liquid–liquid or solid–liquid extraction separation, especially for the latter.© 2013 Wiley Periodicals, Inc. J.
