Systematic Studies on 3 d‐ and 4 f‐Metal Containing Polyoxometalates Suitable for Organic Derivatization†
نویسنده
چکیده
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 studied by NMR spectroscopy, mass spectrometry, and light-scattering techniques.

Construction of different dimensional inorganic-organic hybrid materials based on polyoxometalates and metal-organic units via changing metal ions: from non-covalent interactions to covalent connections.
Five POM-based hybrid materials have been designed and synthesized based on different metal ions under hydrothermal conditions, namely, [Zn(Hfcz)(H(2)O)(3)](H(3)fcz)(SiMo(12)O(40)).3H(2)O (1), [Cd(2)(Hfcz)(6)(H(2)O)(2)](SiMo(12)O(40)).H(2)O (2), [Co(2)(Hfcz)(2)(SiW(12)O(40))](H(3)fcz)(2)(SiW(12)O(40)).10H(2)O (3), [Ni(2)(Hfcz)(4)(H(2)O)(2)](SiW(12)O(40)).5H(2)O (4) and [Ag(4)(Hfcz)(2)(SiMo(12)O...
متن کاملRecent Advances in Crystal Engineering from Nanoscience Views: A Brief Review
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...
متن کاملSpectroscopic readout of polyoxometalates' molecular information via self-assembly.
Polyoxometalates [SiM12O40](4-) (M = Mo(VI), W(VI)) and hemicyanine-derived chiral amphiphiles self-assemble in organic media where intermolecular interactions between POMs and hemicyanine units differ depending on the constituent metal ion species: this information is amplified to distinct spectral and self-assembling characteristics.

In this work, we report the synthesis of silver decamolybdate, Ag6Mo10O33, nanostructure by a simple mechanohemical process followed by calcination treatment using acetamide as driving agent. Morphological study by scanning electron microscopy (SEM) images revealed bundles of rods grown closely together with an average diameter of 92 nm for Ag6Mo10O33 sample. Ni-substituted Ag6Mo10O33 compound ...
متن کاملImmobilization of polyoxometalates in the Zr-based metal organic framework UiO-67.
The encapsulation of polyoxometalates within the large pores of the Zr(iv) biphenyldicarboxylate UiO-67 metal-organic framework has been achieved, for the first time, by direct solvothermal synthesis. The resulting POM@UiO-67 composite materials were fully characterized by XRPD, IR, MAS NMR, N2 porosimetry measurements and cyclic voltammetry.
