Abstract

In this work, the synthesis, characterization, and phosphorescent properties of the coordination polymer, {Ag₃(dppy)₂[μ-SCN]₃}_n (1), are described. X-ray crystallography showed that the complex forms a one-dimensional infinite zipper-like chained structure linked by thiocyanate as the bridging ligand. The silver(I) complex exhibits a strong sky-blue phosphorescence with a high quantum yield of 70.2% in the solid state at ambient temperature. Additionally, following a temperature change from 418 to 77 K, the complex displays a remarkable luminescent thermochromic property.
