“…The self-assembly of nanoparticles (NPs) represents a cuttingedge approach in materials science, enabling the design of novel materials with bespoke structures and functionalities. [1] Unlike traditional methods that rely primarily on altering size and morphology of building blocks, [2,3] and other straightforward parameters to modulate assembly behavior and structure, the manipulation of surface ligands on NPs presents a more nuanced and effective strategy for control. [4] Specifically, the employment of polymeric ligands, including homopolymers and block copolymers, with their versatile spatial configurations, empowers researchers to tailor the surface properties of NPs.…”

The utilization of polymer conformations to construct a variety of superlattices is a common method within the field. However, this technique often results in only long‐range ordering rather than the formation of distinct superlattices. In our study, we successfully obtained a well‐organized array of discrete pancake‐shaped superlattices (DPSs) through the utilization of air‐liquid interface self‐assembly, facilitated by the confined environment created by a block copolymer. It is crucial to note that both the self‐assembly behavior and resulting morphologies of the DPSs can be precisely tuned by adjusting several experimental parameters, most notably the concentration and molecular architecture of the block copolymers. Furthermore, our work provides valuable insights into the formation processes and mechanisms underpinning the DPSs. The approach described here is both straightforward and efficacious, establishing a strong foundation for subsequent research and the development of non‐close‐packed superlattice structures.This article is protected by copyright.

A facile post-assembly approach for the fabrication of non-close-packed gold nanocrystal arrays from binary nanocrystal superlattices

Abstract: Here, we demonstrate a novel approach for fabricating non-close-packed gold nanocrystal arrays using facile one-step post-modification of Cs4PbBr6-Au binary nanocrystal superlattice by electron beam etching of the perovskite phase. The...
