Summary of main observation and conclusion Silver cluster‐assembled materials (SCAMs) are emerging multi‐functional materials and have attracted great attention recently. In this work, we have prepared a new SCAM of {[Ag 18 (S t Bu) 10 (CF 3 COO) 2 (PhPO 3 )(PhPO 3 H) 4 (bpy‐NH 2 ) 2 ]∙(PhPO 3 H 2 )} n (denoted as Ag 18 bpy‐NH 2 ), by a facile one‐pot method. Ag 18 bpy‐NH 2 adopts a chain‐like structure made of Ag 18 clusters bridged by bipyridyl linkers. Ag 18 bpy‐NH 2 exhibits reversible luminescent mechanochromism upon mechanical stimulation and solvent treatment. Moreover, it also displays luminescent thermochromism with a linear relationship of the temperature to the intensity ratio of the dual emissions over a wide temperature range of 83 to 303 K. This work might provide new insights into the assembly of multifunctional stimuli‐responsive SCAMs.
