Abstract

Elucidating the coordination structures and assembling modes of atomically precise metal nanoclusters (NCs) remains a hot topic as it gives answers to underlying mechanism of nanomaterials and bulk materials in...

Ag6Cu8(C=CAr)14(DPPB)2: A Rigid Ligand Co‐Protected Bimetallic Silver(I)‐Copper(I) Cluster with Room‐Temperature Luminescence

“…The presence of aromatic ring structures within peripheral ligands often facilitates the facile crystallization of cluster molecules from solution due to the π-π or H-π interactions. [17] However, the intermolecular associations of Ag 6 Cu 8 are primarily governed by hydrogen bonding between the F and H atoms on the alkyne ligands, [18] as illustrated in Figure 2. This hydrogen bonding interaction plays a significant role in the assembly and crystallization processes of cluster molecules, leading to the formation of macroscopically visible single crystal structures.…”

Cu26 Nanoclusters with Quintuple Ligand Shells for CO2 Electrocatalytic Reduction

“…Atomically precise metal nanoclusters with a crystal structure determined remain a unique class of nanomaterials in terms of their role in illustrating structure–property relationships. − With size, composition, and structure precisely determinable and readily tunable, metal nanoclusters have found wide applications in fields including catalysis, biology, and electronics. − Such nanocatalysts with molecular characteristics have especially been regarded as model systems to probe catalytically active sites and uncover the reaction mechanism of nanocatalysis at the molecular level. − The past several decades have thus witnessed significant efforts in optimizing the activity, selectivity, and stability of cluster-based catalysts in various chemical transformations via multiple strategies such as ligand engineering, composition tuning, and structure tailoring. − In the progress, the reactions have been extended from thermal catalysis and electrocatalysis to photocatalysis, ligands from phosphine, thiol, and alkynyl to N -heterocyclic carbene, and metals from gold, silver, and copper to platinum and palladium. ,− ,− …”

PtAg18 superatoms costabilized by phosphines and halides: synthesis, structure, and catalysis

“…1–16 In particular, the ligands on the surface of metal nanoclusters can not only improve their stability but also play a role in modifying their structural characteristics as well as functions. 17–40 Among the ligands, phosphines, as the pioneering class of candidates for the stabilization of metal nanoclusters, have made significant contribution to the study of the relationship between cluster structures and their properties. 17,31,33,41–46 The spatial site resistance and electronic properties of phosphine ligands can be modulated over a wide range so that the desired properties can be achieved by structural engineering.…”
