由聚（苯乙烯-b-4-乙烯基吡啶甲基碘）-聚氧乙烯酸酯复合胶束，SVP-6，与聚氧乙烯酸酯为基础的超分子星星聚合物，PSP-4，在不同质量的溶剂中的可控相互作用建模的球形聚合物刷，使我们能够调整其自组装行为从自识别到超分子识别。在前一种情况下，孤立的，收缩球连同由PSP-4形成的一些囊泡与由SVP-6形成的多胶束聚集体共存，而在后一种情况下，SVP-6被托管在PSP-4的囊泡内。这项工作代表了一个重要的一步，发展和理解的可编程自组装刷状聚合物成复杂的材料。
The controllable interactions of a spherical polymer brush modeled by a poly(styrene-b-4-vinylpyridinium methyl iodide)-polyoxometalate composite micelle, SVP-6, with a polyoxometalate-based supramolecular star polymer, PSP-4, in solvents of variable quality allow us to tune their self-assembly behaviors from self-recognition to supramolecular recognition. In the former case, isolated, contractive spheres together with a few vesicles formed by PSP-4 coexist with multimicelle aggregates formed by SVP-6, whereas SVP-6 is hosted inside the vesicle of PSP-4 in the latter case. This work represents an important step toward the development and understanding of programmable self-assembly of brushlike polymers into complex materials.
