Combinatorial Hierarchically Ordered 2D Architectures Self‐assembled from Nanocrystal Building Blocks

A one-step, low-cost, and general nanocrystal self-assembly method that covers both the nanometer-scale superlattice and macroscale ordered patterns—that is, hierarchical architectures—is developed. This approach can generate various functional, compositional, and dimensional combinatorial architectures. It may give new opportunities in applications of catalysis, electronics, energy, magnetic devices, and bio-techniques.
