Size- and Shape-Dependent Photoexcitation Electron Transfer in Metal Nanoclusters

Wentao Fan et al.

Summary: There are unresolved fundamental issues regarding metal nanoclusters, including the transformation from face-centered cubic (fcc) to hexagonal close-packed (hcp) structures and photoexcitation electron transfer. This study successfully achieved the fcc-to-hcp structure transformation and revealed size and shape-dependent photoexcitation electron transfer for metal nanoclusters. A new thermally induced ligand exchange method was developed to synthesize a rod-shaped hcp Au42(SCH2Ph)32 nanocluster, which exhibited specific absorption and dual emission properties. The findings also suggest a possible structure transformation pathway and predict a novel rod-shaped hcp Au58(SR)40 nanocluster with a larger aspect ratio. Additionally, a kernel-based middle-to-both ends sp <- sp photoexcitation electron transfer mechanism was observed in rod-like gold nanoclusters, indicating the potential for tunable and practical applications.

Supercrystal engineering of atomically precise gold nanoparticles promoted by surface dynamics

Qiaofeng Yao et al.

Summary: The size, morphology and symmetry of supercrystals made of [Au-25(SR)(18)](-) nanoparticles can be altered by adjusting the surface dynamics of the particles. Excess tetraethylammonium cations play a crucial role in the formation of micrometre-sized hexagonal rod-like supercrystals, which are held together by SR-[Au(I)-SR](4) interparticle linkers. The resulting supercrystals can be systematically tuned by changing the concentration and type of the tetraalkylammonium cations.

Atomically Precise Au42 Nanorods with Longitudinal Excitons for an Intense Photothermal Effect

Yingwei Li et al.

Summary: This study reports a metal-precise rod-shaped Au42(SCH2Ph)32 with a high aspect ratio of the hexagonal-close-packed Au20 kernel, which exhibits intense longitudinal absorption and effective photothermal conversion at low concentrations. The findings demonstrate that Au42 nanorods inherit the longitudinal excitation similar to metallic-state nanorods. This work highlights the potential applications of Au42 nanorods in photothermal converters, biomedical therapy, photoacoustic imaging, and photocatalysis.

Near-Infrared Dual Emission from the Au42(SR)32 Nanocluster and Tailoring of Intersystem Crossing

Lianshun Luo et al.

Summary: The synthesis and photoluminescence of the Au42(PET)32 nanocluster are presented in this work. The nanocluster exhibits dual emission, with fluorescence and phosphorescence at different wavelengths. The emission quantum yield is 11.9% in liquid state and the fluorescence is suppressed while the phosphorescence is enhanced in solid state, which can be explained by interaction-induced transition.

Summary: The study focuses on the boundary between molecular and metallic gold nanoclusters, presenting the synthesis and structural determination of the largest all-alkynyl-protected gold nanocluster, Au-156. The cluster's rod shape with concentric core structure displays metal-like electron dynamics, suggesting Au-156 as a key crossover cluster for the transition from molecular to metallic state. The shape of the cluster is identified as one of the crucial factors in determining the molecular or metallic nature of a gold nanocluster.

Hydrogen Evolution Electrocatalyst Design: Turning Inert Gold into Active Catalyst by Atomically Precise Nanochemistry

Yingwei Li et al.

Summary: In this study, a thiolate (SR)-protected Au-36 Ag-2 (SR)(18) nanocluster with low ligand coverage and a core composed of three icosahedral (I-h) units is reported for efficient catalyzing hydrogen evolution reaction (HER). The Au-36 Ag-2 (SR)(18) exhibits high catalytic activity at lower overpotentials due to its low ligand-to-metal ratio, low-coordinated Au atoms and unfilled superatomic orbitals. This study provides a new strategy for constructing highly active catalysts from inert metals by pursuing atomically precise nanoclusters and controlling their geometrical and electronic structures.

Double-helical assembly of heterodimeric nanoclusters into supercrystals

Yingwei Li et al.

Summary: DNA has long been used as a template for constructing helical assemblies of inorganic nanoparticles, but achieving helices without biological ligands is challenging. Atomically precise nanoclusters protected by ligands demonstrate hierarchical structural complexity, similar to biomolecules. The newly synthesized homodimeric and heterodimeric gold nanoclusters self-assemble into superstructures, with heterodimeric clusters forming more complex helical superstructures driven by van der Waals interactions. The surrounding ligands on the clusters contribute to the assembly through paired steric interactions.
