Hybrid nanoparticle (NP) arrays based on particles of different sizes and chemistries are highly desirable to obtain tunable properties for nanodevices. A simple approach to control the spatial organization of NP mixtures within supramolecular frameworks based on NP size has been developed. By varying the ratio of the NP size to the periodicity of the block-copolymer-based supramolecule, a range of hybrid NP assemblies in thin films, ranging from 1D chains to 2D lattices and 3D arrays and networks of NPs, can be readily generated.
基于不同尺寸和化学性质的混合纳米粒子 (NP) 阵列对于获得可调谐纳米器件的性能非常重要。已经开发出一种简单的方法来控制基于 NP 尺寸的超分子框架内 NP 混合物的空间组织。通过改变 NP 尺寸与基于嵌段共聚物的超分子的周期性的比例，可以在薄膜中容易地生成从 1D 链到 2D 晶格和 3D 纳米粒子的阵列和网络的各种混合 NP 组装体。
