Crystal engineering has recently emerged as a method of choice for the design and construction of organic as well as metal-organic functional materials. Crystal engineering attempts to establish packing trends in whole families of compounds and seeks to establish connections between structure and function. The utility of crystal engineering has also been expanded to the nanoscience and the deve...

An overview of the synthesis, characterization and catalytic applications of polyoxometalates/zeolites composites is given. The solids obtained by direct synthesis of the polyoxometalate in the presence of the zeolite are first described with their applications in catalysis. Those obtained by a direct mixing of the two components are then reviewed. In all cases, special care is taken in the loc...

Composites based on polyoxometalates (POMs) have been increasingly attracted by many researchers due to their multitudinous architectures and excellent redox activities as well outstanding proton electron transport capacities. Lately, much research has done POMs composited with well-porous framework materials (including ZIFs, MOFs) or conducting polymers, carbon quantum dot (CQD), graphene, str...

Magnetic polyoxometalates (POMs) are obtained by a simple sonication between functionalized magnetic nanoparticles and polyoxometalates. This material can be used not only as a highly active acid catalyst, but also as a catalyst support for chiral amines.

We are delighted to introduce this special issue of Inorganics. This themed issue is dedicated to polyoxometalates (POMs) as an outstanding class of oxo-cluster materials. Polyoxometalates have fascinated generations of researchers since the mid-18th-century, and they continue to attract promising young scientists all over the world. Since the first pioneering studies, the manifold structures a...

Self-assemblyings of surfactant-encapsulated Wells-Dawson polyoxometalates (SEPs) nanobuilding blocks in butanone and esters yielded supramolecular gels showing thermo and photo responsive properties. The gels can be further polymerized if unsaturated esters were used and subsequently electrospinned into nanowires and non-woven mats. The as-prepared non-woven mats have a Young's modulus as high...

Premium polyoxometalates! The organic functionalization of 3 d-metalsubstituted polyoxometalates and the synthesis of new metal-oxo clusters with accessible 3 d- and 4 f-metal centers suitable for organic derivatization are discussed in this thesis. A total number of 39 compounds were structurally characterized, and their luminescent and magnetic properties analyzed. The solution behavior was s...
