Abstract Silver chalcogenolate cluster assembled materials (SCAMs) are a category of promising light‐emitting materials the luminescence of which can be modulated by variation of their building blocks (cluster nodes and organic linkers). The transformation of a singly emissive [Ag 12 (SBu t ) 8 (CF 3 COO) 4 (bpy) 4 ] n (Ag 12 bpy, bpy=4,4′‐bipyridine) into a dual‐emissive [(Ag 12 (SBu t ) 6 (CF 3 COO) 6 (bpy) 3 )] n (Ag 12 bpy‐2) via cluster‐node isomerization, the critical importance of which was highlighted in dictating the photoluminescence properties of SCAMs. Moreover, the newly obtained Ag 12 bpy‐2 served to construct visual thermochromic Ag 12 bpy‐2/NH 2 by a mixed‐linker synthesis, together with dichromatic core–shell Ag 12 bpy‐2@Ag 12 bpy‐NH 2 ‐2 via solvent‐assisted linker exchange. This work provides insight into the significance of metal arrangement on physical properties of nanoclusters.
