The inability to synthesize hierarchical structures with independently tailored nanoscale and mesoscale features limits the discovery of next-generation multifunctional materials. Here we present a predictable molecular self-assembly strategy to craft nanostructured materials with a variety of phase-in-phase hierarchical morphologies. The compositionally anisotropic building blocks employed in the assembly process are formed by multicomponent graft block copolymers containing sequence-defined side chains. The judicious design of various structural parameters in the graft block copolymers enables broadly tunable compositions, morphologies and lattice parameters across the nanoscale and mesoscale in the assembled structures. Our strategy introduces advanced design principles for the efficient creation of complex hierarchical structures and provides a facile synthetic platform to access nanomaterials with multiple precisely integrated functionalities.

无法合成具有独立定制的纳米级和中尺度特征的层次结构限制了下一代多功能材料的发现。在这里，我们提出了一种可预测的分子自组装策略来制作具有各种相入的纳米结构材料。-阶段层次形态。组装过程中采用的组成各向异性的构建块由包含序列定义的侧链的多组分接枝嵌段共聚物形成。接枝嵌段共聚物中各种结构参数的明智设计使得组装结构中跨越纳米尺度和中尺度的组成、形态和晶格参数能够广泛可调。我们的策略引入了用于高效创建复杂层次结构的先进设计原则，并提供了一个简便的合成平台来获取具有多种精确集成功能的纳米材料。
