无法合成具有独立定制的纳米尺度和介观尺度特征的分级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，以制作具有各种相内分级形态的纳米结构材料。在组装过程中采用的组成各向异性的结构单元由含有序列限定的侧链的多组分接枝嵌段共聚物形成。在接枝嵌段共聚物中的各种结构参数的明智设计使得能够在组装的结构中跨越纳米尺度和介观尺度广泛地调节组合物、形态和晶格参数。我们的战略引入了先进的设计原则，以有效地创建复杂的分层结构，并提供了一个简便的合成平台，以获得具有多种精确集成功能的纳米材料。
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.
