A disulfur ligand stabilization approach to construct a silver(<scp>i</scp>)-cluster-based porous framework as a sensitive SERS substrate

Abstract

An atomic-precise silver(<sc>i</sc>)-cluster-based MOF (<bold>UJN-1</bold>) stabilized by disulfur ligand has been demonstrated. Its reduced derivative exhibits highly sensitive SERS activity that can be ascribed to abundant hot spots sites and porosity structure.
