Hybrid Polyoxometalates: Keggin and Dawson Silyl Derivatives as Versatile Platforms

A new series of polyoxometalate-based hybrids has been synthesized. These covalently linked organic−inorganic materials represent valuable elementary building blocks ready for postfunctionalization, using classical organic reactions and couplings. This approach is exemplified by the grafting of an organic chromophore via a Sonogashira coupling.
