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 (λmax = 550 nm) with a short lifetime (2.4 μs) and a moderate emission quantum yield (16 %).
