| Summary: | Polyoxometalates (POMs) represent an important group of metal-oxo nanoclusters, typically comprised of early transition metals in high oxidation states (mainly V, Mo and W). Many plenary POMs exhibit good pH, solvent, thermal and redox stability, which makes them attractive components for the design of covalently integrated hybrid organic-inorganic molecules, herein referred to as hybrid-POMs. Until now, thousands of organic hybrid-POMs have been reported; however, only a small fraction can be further functionalized using other organic molecules or metal cations. This emerging class of 'post-functionalizable' hybrid-POMs constitute a valuable modular platform that permits coupling of POM properties with different organic and metal cation functionalities, thereby expanding the key physicochemical properties that are relevant for application in (photo)catalysis, bioinorganic chemistry and materials science. The post-functionalizable hybrid-POM platforms offer an opportunity to covalently link multi-electron redox responsive POM cores with virtually any (bio)organic molecule or metal cation, generating a wide range of materials with tailored properties. Over the past few years, these materials have been showcased in the preparation of framework materials, functional surfaces, surfactants, homogeneous and heterogeneous catalysts and light harvesting materials, among others. This review article provides an overview on the state of the art in POM post-functionalization and highlights the key design and structural features that permit the discovery of new hybrid-POM platforms. In doing so, we aim to make the subject more comprehensible, both for chemists and for scientists with different materials science backgrounds interested in the applications of hybrid (POM) materials. The review article goes beyond the realms of polyoxometalate chemistry and encompasses emerging research domains such as reticular materials, surfactants, surface functionalization, light harvesting materials, non-linear optics, charge storing materials, and homogeneous acid-base catalysis among others.
The post-functionalizable hybrid-polyoxometalate platforms offer an opportunity to covalently link redox responsive POM cores with virtually any organic molecule or metal cation, generating a wide range of materials with tailored properties. |

| Bibliography: | Aleksandar Kondinski graduated from Jacobs University Bremen in 2010 with a BSc in Chemistry. He completed his PhD under the supervision of Prof. Thomas Heine at the same university in 2016. After a postdoc at RWTH Aachen University under the supervision of Prof. Paul Kögerler, he joined Prof. Parac-Vogt to study hybrid organic-inorganic materials. His research interests include development of advanced polyoxometalates for nanoelectronics and catalytical applications. Dr Anyushin obtained his PhD from Nikolaev Institute of Inorganic Chemistry, Siberian Branch of the Russian Academy of Sciences. During his postdoctoral studies at Nikolaev Institute, Dr Anyushin investigated novel synthetic approaches in noble metal chemistry and in the chemistry of hybrid organic-inorganic compounds, including transition metal clusters and polyoxometalates. He is currently a post-doc in the group of Prof. Parac-Vogt at KU Leuven where he is focusing on developing functional biopolymer-metal-oxo hybrid materials. Dr Anyushin has an enduring interest in the areas of organic-inorganic hybrid molecules, polyoxometalate-based functional materials for catalysis and bio-inorganic hybrid systems. Tatjana N. Parac-Vogt is a full professor of chemistry at KU Leuven, Belgium. She studied chemistry at the University of Belgrade, former Yugoslavia, and obtained her PhD from Iowa State University in Ames, USA. Following her PhD, she performed post-doctoral research at the University of California at Berkeley in the group of Professor Ken Raymond. After that she spent two years in Germany as Alexander von Humboldt Fellow, before moving to KU Leuven in 2000, where she is currently the head of the Laboratory of Bioinorganic Chemistry. She has an active interest in promoting gender and cultural diversity in the working environment, and is also active as a coach and mentor to younger female scientists.
