Recent advances in POM-organic frameworks and POM-organic polyhedra.

In this review, the recent advancements of POMOFs and POMOPs, including their assembly methodologies, classification and related applications are summarized. Moreover, the current challenges in the design and fabrication of POMOFs and POMOPs as well as the great potential in these two areas are also discussed. • The recent advancements of POMOFs and POMOPs are summarized. • The advantages of using POM clusters to construct POMOFs and POMOPs are summarized. • Synthetic strategies for further development of POMOFs and POMOPs are presented. • Understanding the structure-property relationships of POMOFs and POMOPs. • The current challenges and the great potential of POMOFs and POMOPs are discussed. During the past two decades, the search of strategies to introduce polyoxometalate (POM) clusters as secondary building units (SBUs) to construct porous extended POM-organic frameworks (POMOFs) and discrete POM-organic polyhedra (POMOPs) have attracted sustained interests because such materials not only integrate the advantages of both POMs and framework/polyhedra structures, but also exhibit good prospects in photo-/electro-catalysis, separation, molecular recognition, host-guest chemistry and so on. In this review, the recent advancements of POMOFs and POMOPs, including their assembly methodologies, classification and related applications are summarized. Moreover, the current challenges in the design and fabrication of POMOFs and POMOPs as well as the great potential in these two areas are also discussed. [ABSTRACT FROM AUTHOR]
