Building Block Metal Nanocluster‐Based Growth in 1D Direction

Abstract

Metal nanoclusters with precisely modulated structures at the nanoscale give us the opportunity to synthesize and investigate 1D nanomaterials at the atomic level. Herein, it realizes selective 1D growth of building block nanocluster “Au13Cd2” into three structurally different nanoclusters: “hand‐in‐hand” (Au13Cd2)2O, “head‐to‐head” Au25, and “shoulder‐to‐shoulder” Au33. Detailed studies further reveals the growth mechanism and the growth‐related tunable properties. This work provides new hints for the predictable structural transformation of nanoclusters and atomically precise construction of 1D nanomaterials.

Extensive Polymerization of Atomically Precise Alloy Metal Clusters During Solid-State Reactions

“…Supramolecular interactions between metal clusters have been utilized for the bottom-up fabrication of nanomaterials. − Directed self-assembly of clusters results in the formation of polymers of atomically precise clusters. − However, controlled self-assembly of clusters has been challenging, and Yuan et al introduced a solvent-mediated approach for precisely synthesizing polymers of clusters . In this work, we show that clusters can also interact with each other in the solid state, resulting in the exchange of metal atoms, which was not studied previously.…”
