Alkynyl Approach toward the Protection of Metal Nanoclusters.
TLDR
This Account describes the development of coinage metal nanoclusters protected with alkynyl ligands, and presents the direct reduction method for the synthesis of the following four categories ofnanoclusters: gold nanocluster with mixed-ligand shells, all alkyny-protected gold nanocusters, (c) heterobimetallic gold Nanoclusters, and (d) silver nanocl clusters.
Au20 nanocluster protected by hemilabile phosphines.
TLDR
This is the first example of a ligand-protected gold nanocluster with a core generated from incomplete icosahedral Au(11) building units.
Isolation and Total Structure Determination of an All-Alkynyl-Protected Gold Nanocluster Au144.
TLDR
The work not only addresses the concern of structural information of Au144 , which had been long-pursued, but also provides an interesting example showing ligand effects on the optical properties of ligand protected metal nanoclusters.
A chiral gold nanocluster Au20 protected by tetradentate phosphine ligands.
TLDR
The first structural determination of a gold nanocluster containing an intrinsic chiral inorganic core is reported and single-crystal structural determination reveals that the cluster molecular structure has C3 symmetry.
Alkynyl-protected gold and gold-silver nanoclusters.
TLDR
It is demonstrated that alkynyls are very promising ligands in the control of the structures and properties of gold/silver nanoclusters.
Ligand effects in catalysis by atomically precise gold nanoclusters
TLDR
This work presents a clear demonstration that catalytic performance of gold nanoclusters can be modulated by the controlled construction of ligand spheres.
Atomically Precise Alkynyl-Protected Metal Nanoclusters as a Model Catalyst: Observation of Promoting Effect of Surface Ligands on Catalysis by Metal Nanoparticles.
TLDR
It is, for the first time, demonstrated that the organic-capped metal nanoclusters work as active catalysts much better than those with surface ligands partially or completely removed.
Au19 nanocluster featuring a V-shaped alkynyl-gold motif.
A novel Au19 nanocluster with a composition of [Au19(PhC≡C)9(Hdppa)3](SbF6)2 was synthesized (Hdppa = N,N-bis(diphenylphosphino)amine). Single crystal X-ray structural analysis reveals that the…
Thiacalix[4]arene: New protection for metal nanoclusters
TLDR
Thiacalix[4]arene has been used in the synthesis of a silver nanocluster, the first structurally determined calixarene-protected metal nanoclusters, and suggests a bright future for metal Nanoclusters protected by macrocyclic ligands.
A Near-Infrared-Emissive Alkynyl-Protected Au24 Nanocluster.
TLDR
An alkynyl-protected gold nanocluster that is highly emissive in the near-infrared region with λ(max)=925 nm and the nature of the HOMO-LUMO transition is investigated by time-dependent DFT calculations.
