Polymer-containing Organo-Polyoxometalate: Towards New Catalytic Object.

Polyoxometalates (POMs) are early transition metal oxide clusters, which form a diverse family of compounds with highly tunable shapes, sizes, charges, etc. Generating hybrid structures is an attractive path to increase the structural diversity of POMs. The present article is a personal account that retraces how we inserted polyoxometallic platforms onto polymeric chains. We focused on two main families of functionalized organo-POMs: the organotin-substituted Dawson polyoxotunstates α1 and α2-[P(2)W(17)O(61)(SnR)](7-) and the Dawson vanadotungstates [P(2)V(3)W(15)O(59){(OCH(2))(2)-C(Et)NHC(=O)R}](5-). Herein we discuss how the connection of POMs to polymers affects the self-assembly of the polymers and the catalytic properties of the polyoxometalates.
