Reversible Wide‐Range Tuneable Luminescence of a Dual‐Stimuli‐ Responsive Silver Cluster‐Assembled Material

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 {Ag₁₈(S^tBu)₁₀(CF₃COO)₂(PhPO₃)(PhPO₃H)₄(bpy‐NH₂)₂]?(PhPO₃H₂)}_n (denoted as Ag₁₈bpy‐NH₂), by a facile one‐pot method. Ag₁₈bpy‐NH₂ adopts a chain‐like structure made of Ag₁₈ clusters bridged by bipyridyl linkers. Ag₁₈bpy‐NH₂ 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.
