Hybrid materials with hierarchical nanostructures are of great interest for their advanced functions. However, the effect of the formation of hierarchical nanostructures on properties is not well understood. Here, through combining dissipative particle dynamics simulation and the finite‐difference time‐domain method, the optical properties of hierarchically ordered nanostructures formed by mixtures of A(BC)_n multiblock copolymers and nanoparticles (NPs) are investigated. A series of hierarchically ordered nanostructures with multiple small‐length‐scale hybrid domains are obtained from the self‐assembly of A(BC)_n /NP. An increase and blueshift in optical absorption are observed when the number of small‐length‐scale hybrid domains increases. The small‐length‐scale hybrid domains enhance light scattering, which consequently contributes to the improved optical performance. These findings can yield guidelines for designing hierarchically ordered functional nanocomposites with light‐harvesting characteristics.

由多嵌段共聚物/纳米粒子混合物自组装的分层有序纳米结构的独特光学性质。

具有分层纳米结构的混合材料因其先进的功能而备受关注。但是，人们还不太了解分层纳米结构的形成对性能的影响。在这里，通过结合耗散粒子动力学模拟和时域有限差分法，研究了由A（BC）_n 多嵌段共聚物和纳米粒子（NPs）的混合物形成的分层有序纳米结构的光学特性。从A（BC）_n的自组装获得一系列具有多个小长度尺度杂化域的分层有序纳米结构 / NP。当小长度尺度混合域的数量增加时，观察到光吸收的增加和蓝移。小长度尺度混合域增强了光散射，因此有助于改善光学性能。这些发现可以为设计具有光收集特性的层次有序的功能纳米复合材料提供指导。
