Extensive Polymerization of Atomically Precise Alloy Metal Clusters During Solid-State Reactions.

Exploring the reactions between atomically precise metal clusters and the consequences of such reactions has been an exciting field of research during the past decade. Initial studies in the area were on reactions between clusters in the solution phase, which proceed through the formation of dimers of reacting clusters. In the present work, we examine the interaction between two atomically precise clusters, [Au(PET)] and [Ag(DMBT)], in the solid state, where PET and DMBT are 2-phenylethanethiol and 2,4-dimethylbenzenethiol, respectively.

Macropolyhedral -BH, the "Forgotten" Isomer.

The chemistry and physics of macropolyhedral BH clusters have attracted significant attention due to the interesting photophysical properties of -BH (blue emission, laser properties) and related potential applications. We have focused our attention on the "forgotten" -BH isomer, which has received very little attention since its discovery compared to its -BH isomer, presumably because numerous studies have reported this isomer as nonluminescent. In our study, we show that in crystalline form, -BH exhibits blue fluorescence and becomes phosphorescent when substituted at various positions on the cluster, associated with peculiar microstructural-dependent effects.

Secondary ligand-induced orthogonal self-assembly of silver nanoclusters into superstructures with enhanced NIR emission.

Orthogonal self-assembly is one of the crucial strategies for forming complex and hierarchical structures in biological systems. However, creating such ordered complex structures using synthetic nanoparticles is a challenging task and requires a high degree of control over structure and multiple non-covalent interactions. In this context, nanoarchitectonics serves as an emerging tool to fabricate complex functional materials.
