A multivalent mixed-metal strategy for single-Cu+-ion-bridged cluster-based chalcogenide open frameworks for sensitive nonenzymatic detection of glucose

Abstract

Here we report two new metal-chalcogenide open frameworks (MCOFs) with large-sized supertetrahedral clusters bridged by an accessible single-cuprous ion via a multivalent mixed-metal strategy. Such Cu-rich semiconductor MCOFs have been investigated for the first time for nonenzymatic detection of glucose, and display good sensitivity and stability.
