Diphosphoryl‐functionalized Polyoxometalates: Structurally and Electronically Tunable Hybrid Molecular Materials

Angewandte Chemie, Volume 135, Issue 23, June 5, 2023., 2023
The synthesis and characterization of a new class of hybrid diphosphoryl Wells–Dawson polyoxometalate (POM) is described. The covalent tethering of diphosphoryl compounds to the inorganic cluster gives redox‐active materials with enhanced hydrolytic stability compared to the corresponding phosphonate analogues.
