CuI-Based Coordination Polymer Assembled from a 2-Pyridyl Sulfide Ligand: Synthesis and Luminescent Properties

Abstract

2-Ehtylthiopyridine (L) reacts with CuI (MeCN, r.t.) to afford a 1D chain coordination polymer (CP), [Cu₂I₂(L)]_n in a 75% yield. The latter consists of double-stranded (Cu₂I₂)_n ribbons ligated on both sides by 2-ehtylthiopyridines in a 1,3-N,S bridging manner. In the solid state at 298 K, this CP displays yellow-green photoluminescence (λ_max = 550 nm) with a short lifetime (2.4 µs) and a moderate emission quantum yield (16%).
