Abstract

Luminescent Silver Clusters In article number 2500700, Yoshiki Niihori, Yuichi Negishi, and co-workers showed the syntheses of novel Ag54 clusters, composed of silver and sulfur and protected by thiolate and sulfonate, with a large internal cavity that can encapsulate sulfide and iodide ions. The encapsulation of iodide ions into Ag54 enhances spin-orbit interaction and improves phosphorescence properties.
