Abstract

Replacement of secondary ligands enhance the luminescence 30-fold in Ag29 cluster.

Molecular reactivity of thiolate-protected noble metal nanoclusters: synthesis, self-assembly, and applications

“…1), which have been widely used to customize the size, structure, surface chemistry and properties of metal NCs. 7,[111][112][113] Ligand exchange reactions largely depend on the etching reaction of the foreign ligands on the existing M-SR interface of the metal NCs. As M(I)-SR motifs have been discovered with various structures and arrangement patterns on the surface of the M(0) core, the chemical environment of SR ligands can be diverse in the metal NCs.…”

Self‐Assembly of Precision Noble Metal Nanoclusters: Hierarchical Structural Complexity, Colloidal Superstructures, and Applications

“…PL quantum yield of NCs is lower compared to semiconductor quantum dots or organic dyes. However, one could improve the PL of NCs by ligand engineering, [ 353 ] encapsulation of NCs inside protein pockets, [ 354,355 ] self‐assembly, [ 319 ] doping, [ 356–358 ] and AIE. [ 28,359–361 ] AIE has been further investigated in the self‐assembled superstructures originated from different NCs, and their potential applications have been reviewed.…”

Regulation of Surface Structure of [Au9Ag12(SAdm)4(Dppm)6Cl6](SbF6)3 Nanocluster via Alloying

“…Atomically precise core-shell nanoclusters have become a promising material in catalysis, biomedicine, and chemical sensing due to the unique quantum confinement effect resulting in optical properties ( Jin et al, 2016 ; Yao et al, 2018 ; Xu et al, 2019 ; Jin R. et al, 2021 ; Sun et al, 2021 ; Zheng et al, 2021 ). The studies on correlation between the properties and structures of cluster compounds based on the determined crystal structures show that the core and shell structures have different effects on the performance of the cluster compounds, and modifications on the core and shell structures may induce variations on clusters properties ( AbdulHalim et al, 2014 ; Chakraborty and Pradeep, 2017 ; Khatun et al, 2018 ; Yan et al, 2018 ; Jin Y. et al, 2021 ). The Pt core-doped nanocluster PtAu 24 (SC 6 H 13 ) 18 exhibits higher hydrogen production than that of Au 25 ( Kwak et al, 2017 ), and the dopant AuAg 24 shows stronger fluorescence performance ( Bootharaju et al, 2016 ).…”
