We present a concise review of the large variety of self-assembly scenarios observed in solutions of diblock copolymer stars with a solvophilic inner block and a solvophobic outer block. A variety of modeling approaches and simulation techniques at different levels of detail reveals that individual molecules assume configurations akin to patchy colloids, but with a patchiness that depends on physical parameters and can adjust to external stimuli such as temperature and pH. These soft, patchy building blocks inter-associate at finite concentrations into micellar or gel-like solutions, including spherical and wormlike micelles, or they display macroscopic phase separation. The connections between single-molecule conformation and the structure of the concentrated solution are discussed, and coarse-grained strategies for these novel molecular entities are critically compared to one another.

我们对在具有亲溶剂性内嵌段和疏溶剂性外嵌段的二嵌段共聚物星的溶液中观察到的各种自组装情况进行了简要的综述。各种建模方法和模拟技术在不同的细节级别上揭示，单个分子的构型类似于斑驳的胶体，但斑驳程度取决于物理参数，并可以适应外部刺激（例如温度和pH）。这些柔软的，斑驳的结构单元以有限的浓度相互关联成胶束或凝胶状溶液，包括球形和蠕虫状的胶束，或者它们表现出宏观的相分离。讨论了单分子构象与浓缩溶液结构之间的联系，
