A sky-blue luminescent silver(I) complex with a one-dimensional zipper-like structure constructed with 2-diphenylphosphinopyridine and thiocyanate

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.
