Polymer-containing Organo-Polyoxometalate: Towards New Catalytic Object

Abstract

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 ?1 and ?2-[P2W17O61(SnR)]7– and the Dawson vanadotungstates [P2V3W15O59{(OCH2)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.
