Summary: Four silver thiolate clusters with similar nestlike structures were studied, showing tunable solid-state emissions depending on the templating anions. The color of emissions could be adjusted from green to orange and then to red by changing the template anions, indicating a correlation to charge transfer between the templates and metal atoms. This work contributes to the understanding of the templating role of heteroanions and the relationship between structure and properties.

Summary: In this study, we introduce an efficient hybrid copper(I) iodide cluster emitter (DBA)(4)Cu4I4, which achieves ultra-bright triplet yellow-orange emission with a photoluminescence quantum yield over 94.9% through the cooperation of excited state structure reorganization and the metallophilicity interaction. The phonon-assisted de-trapping process of exciton induces the negative thermal quenching effect at 80-300 K. Furthermore, our (DBA)(4)Cu4I4 wafer shows great potential in practical X-ray imaging applications with a light yield higher than 10(4) photons MeV-1 and a high spatial resolution of approximate to 5.0 lp mm(-1). This new copper(I) iodide cluster emitter can be used as a model for investigating the thermodynamic mechanism of photoluminescence in hybrid copper(I) halide phosphorescence materials.

Summary: With the use of anion template-driven self-assembly, we have achieved precise control over the shape and size of silver nanoclusters, reporting the atomically precise structures of Ag37 and Ag46. The results reveal that Cl- ions serve as both local and global templates in Ag37, while CrO42- ions function as local templates with Cl- ions as global templates in Ag46. By utilizing the deep cavity of thiacalix[4]arene with an extended phenyl group, Ag46 has been successfully used as a host material for dye adsorption depending on the charge and size of organic dyes. The study fills the knowledge gap in understanding the directing role of heteroanions in dictating the shape and size of nanoclusters at the atomic level.

Summary: This study presents an atom-precise 18-copper nanocluster (Cu18H) with a pseudo D-3-symmetrical triple-helical Cu-15 core. Cu18H exhibits unique multi-layered 3D chirality and forms an infinite double-stranded helix through intra-strand and inter-strand interactions. The hierarchical assemblies of Cu18H not only resemble the structure of DNA but also exhibit crystallization-induced emission enhancement and aggregation-induced emission enhancement effects, as well as efficient catalysis of electron transfer reactions.

Summary: Despite being a relatively weak supramolecular force, the C-H...O interaction presents a significant challenge in the crystal engineering of complex metallosupramolecules. By altering the composition ratio of a ternary solvent system, the intermolecular C-H...O interaction can be tuned to control the formation of one-dimensional metal cluster polymorphs and modulate their temperature-dependent photoluminescence behavior and photothermal conversion properties, which can be applied in remote-controlled laser ignition.

Summary: In this study, an all-alkynyl-protected gold nanocluster, Au20, with distinguished photophysical properties including near-infrared dual-emission (DE) at 820 and 940 nm and high photo-luminescent quantum yield, was synthesized. Through systematic spectroscopic and theoretical studies, two triplet charge transfer states, ligand-to-kernel and kernel-based CT states, were identified as the origins of DE. The NIR DE also exhibited highly independent and sensitive responses to surrounding environments. This work provides insights into the DE mechanism and promotes the development of NIR DE materials.

Summary: Accurate identification and understanding of defect sites in nanomaterials are crucial for establishing defect-activity relationships. However, the synthesis and isolation of atomically precise coinage-metal nanoclusters with surface vacancy defects are challenging. In this study, a mixed-ligand strategy was employed to synthesize a chiral and metal-deficient copper nanocluster with high hydrogen content. Its crystal structure reveals specific defect sites and experimental results prove its catalytic activity in the hydrogenation reaction. This work paves the way for further research on well-defined chiral metal-deficient nanoclusters and their applications in asymmetrical catalysis.

Summary: Ligand shells of gold nanoclusters have significant effects on their molecular and electronic structures. The study compares the impacts of two similar but distinct protecting ligands, Au13As8 and Au13Sb8. Au13As8 exhibits a blue-shifted electronic absorption band, which is attributed to stronger p-back donation interactions between Au-13 core and AsPh3 ligands. Furthermore, Au13As8 demonstrates better balance between catalytic stability and activity compared to Au13Sb8, making it a promising precursor cluster for further cluster preparation.
