Overview. Studies in our laboratory concern concern the use of metal-oxide cluster-anions (polyoxometalates, or POMs) for addressing fundamental problems in electron transfer, catalysis, host/guest chemistry and nanoscience, and as building blocks for functional supramolecular assemblies. Studies range from fundamental investigations of inorganic reaction mechanisms to explorations of supramolecular structures formed by electrostatic, hydrogen-bonded or hydrophobic interactions.

Metal-oxide cluster science. POMs are typically prepared from early-transition metals (V, Mo, and W) in their highest oxidation states (d0, and sometimes d1, electronic configurations). Many POMs possess extensive and reversible redox chemistries, and as a class, their compositions and structures, which control the physical and chemical properties that impart functionality, can be rationally modified at the atomic level.  Functional systems are prepared through the incorporation of reactive components, such as transition-metal ions, by control over the nanoscale architectures of larger metal-oxide (POM) frameworks, and by use of POM clusters as components of supramolecular and nanoscale assemblies.
