Silver nanocluster assemblies are an emerging class of fluorescent and stable solid materials by virtue their structural tunability stability compared to isolated clusters. The photophysical properties the cluster nodes influenced intra- or intercluster interaction. In this work, we show two-dimensional (2D) [Ag5(C2tBu)2(CF3COO)3(C4H4N2)](CHCl3) three-dimensional (3D) [Ag4(C2tBu)(CF3COO)3(C4H4N2)] silver obtained tuning molar ratios same protecting ligands linker. 2D assembly possesses a one-dimensional (1D) chain held together through Ag···Ag interactions, whereas in 3D assembly, Ag4 units linked trifluoroacetate form 1D with Ag4-O-Ag4 Ag4-O-C-O-Ag4 connectivity. This varying effect argentophilic interaction influences photoluminescence properties. emission was found be dominated cluster-centered state owning enhanced 3D, is from theoretical investigations also revealed that lowest unoccupied molecular orbitals (LUMOs) localized on pyrazine contrast, LUMOs mostly metal atoms within cluster. work highlights not only importance synthesis but emphasizes understanding structure-luminescence relationship.
