Luminescent silver clusters that are confined inside porous zeolites have attracted great research interest due to the combined advantages of high quantum yield, tunable emission, excellent chemical stability, and desirable adoption ability of this micronano-composite. In this research, a series of Ag-exchanged R-LTA/Ag (R = Li, Na, K) zeolites were synthesized, in which the silver clusters showed blue-shifted excitation in the UV region, red-shifted emission in the visible region, and decreased emission intensity when taking Li, Na, and K as the extra-framework cations, respectively. The [Ag(HO)R-sod] ( = 2, 4; R = Li, Na, K) structures were constructed, and the TD-DFT method was further carried out to study the influence of extra-framework cations on the luminescence performance of [Ag] clusters, in which the substitution of Al for Si and the reasonable hydrate levels were both taken into consideration.

Article Synopsis
- Cluster-based spin crossover (SCO) frameworks are innovative metal-organic frameworks (MOFs) that exhibit unique properties and diverse structures.
- The study highlights the synthesis of a specific SCO framework [Fe3{Ag4(CN)6(H2O)}2(TPBA)3](ClO4)2·7DMF (1) featuring a rare topology and a complex network composed of metal clusters and Fe2+ ions.
- Additionally, the research demonstrates effective post-synthetic modifications that allow transformation between different topologies while retaining their spin crossover behaviors, paving the way for advanced smart porous materials.

Elucidating the correlations between the core structure of atomically precise nanoclusters and their catalytic activities is fundamentalfor exploring highly efficient nanocatalysts. Herein, a series of Ag-based nanoclusters protected by 2,4-dimethylphenylthiophenol (specifically AgPd(SPhMe) and AgM(SPhMe) where M = Ag, Pd, and Pt) were synthesized and deposited on TiO supports as heterogeneous catalysts for the selective hydrogenation of nitroarenes with NaBH as the reductant. It was found that AgPd(SPhMe) could spontaneously lose its ligands during catalysis, leading to the formation of polydispersed AgPd nanoparticles.
