What is it about?

We reported an efficient preparation of original hybrid polyoxometalates. In these compounds the electronic communication between the organic chain and the inorganic part is impressive and could be fine tuned by the modification of the organic side chain. An X-ray structure confirms the anchoring of the organic via two alcohols and an amide functions

Why is it important?

The insertion of an amide carbonyl into the polyanionic structure is new and allows the electronic communication between the organic and inorganic parts. That allowed us to play with the redox potential of the POM or the organic side chain (reported later in other publications).

Perspectives

We later used that kind of compounds for chemoselective oxidation of sulfur (Organic Letters, 2011, 13, 22, 5990); controlled preparation of Palladium complexes (Organic Letters, 2014, 16, 15, 3860) or POM -Porphyrin Copolymers (Chemistry - A European Journal, 2015, 21, 8271). See also the work from C.P. Pradeep and coll ([P2V3W15O62]9 − cluster based covalent polyoxometalate-organic hybrid: Synthesis, structure, self-assembly and in vitro antioxidant activities (Inorganic Chemistry Communications, 2015, 56, 65).
