Stabilization and immobilization of polyoxometalates in porous coordination polymers through host–guest interactions

The stabilization and immobilization of polyoxometalates (POMs) through the formation of POM-containing coordination polymers is one of the more attractive areas of supramolecular chemistry and POM materials. Owing to their various structural topologies and chemical compositions, which endow them with tunable shape, size and high negative charges, POMs are remarkably versatile building blocks in the construction of coordination supramolecules. Frequently, POMs act as anionic templates to build three-dimensional metal organic frameworks. In this review, we summarize the structures of POM-containing coordination polymers in which the combination of POMs and metal–organic polymers is through host–guest supramolecular interactions, such as weak coordination interactions, electrostatic interaction, and hydrogen bonding.
