New protective ligands for atomically precise silver nanoclusters

Abstract

New-type protecting ligands beyond the conventional ones are beginning to be introduced in stabilizing new silver NCs.

Homoleptic Alkynyl‐Protected Ag15 Nanocluster with Atomic Precision: Structural Analysis and Electrocatalytic Performance toward CO2 Reduction

“…400 nm for Ag nanoparticles. [11,12] Recent years have witnessed the great success of the synthesis,s tructural determination, and appli-cation of Ag NCs,particularly those stabilized by thiolate and phosphine ligands. [11,[13][14][15][16][17][18][19][20][21][22] Recent ligand engineering has also extended to alkynyl for protecting the Ag core,a nd alkynyl ligands exhibit more diverse binding modes on the metal surface and drastically different properties and functionalities.…”

[23] So far, the crystallographically resolved all-alkynylprotected Ag NCs include Ag 74 (PhCC) 44 ,A g 51 ( t BuCC) 32 and so on, [24][25][26][27] but Ag NCs with full alkynyl protection hasnt been reported for CO 2 RR.…”

Homoleptic Alkynyl‐Protected Ag15 Nanocluster with Atomic Precision: Structural Analysis and Electrocatalytic Performance toward CO2 Reduction

“…Note that, due to the strong quantum confinement effect, atomically precise Ag NCs often display significantly different physiochemical properties from those of the larger nanoparticle counterparts, e.g., discrete absorption peaks for Ag NCs instead of the surface plasmon band at ca. 400 nm for Ag nanoparticles [11, 12] . Recent years have witnessed the great success of the synthesis, structural determination, and application of Ag NCs, particularly those stabilized by thiolate and phosphine ligands [11, 13–22] .…”

Structural Diversity and Argentophilic Interactions in Small Phosphine Silver(I) Thiolate Clusters

“…Atomically precise control over the geometry and size of silver‐sulfur based clusters has attracted much attention [1–5] due to the importance of the structure‐property relationships [6–8] in the construction of novel materials for diverse applications such as catalysis, [9] sensing [10,11] and luminescence [12–15] . The assembly, geometry, and size, of silver chalcogenide and halide clusters is often influenced by auxiliary ligands [16–18] …”
