Self‐Assembly of Nanometer‐Scale [Cu₂₄I₁₀L₁₂]¹⁴⁺ Cages and Ball‐Shaped Keggin Clusters into a (4,12)‐Connected 3D Framework with Photoluminescent and Electrochemical Properties

Abstract

Bridging two traditional but distinct research areas—polyoxometalate chemistry and cuprous halide clusters—the (4,12)-connected 3D framework (NH4)[Cu24I10L12][PMoV2MoVI10O40]3 has been built by covalent linkage of nanoscale Keggin anions and [Cu24I10L12]14+ clusters (see picture; L is a multidentate N-heterocyclic ligand); it exhibits remarkable photoluminescent and electrochemical properties.
