Trisubstituted heteropolytungstates as soluble metal oxide analogs. III. Synthesis, characterization, phosphorus-31, silicon-29, vanadium-51, and 1- and 2-D tungsten-183 NMR, deprotonation, and proton mobility studies of organic solvent solute forms of HxSiW9V3O40x-7 and HxP2W15V3O62x-9

Slow‐Proton Dynamics within a Zirconium‐Containing Sandwich‐Like Complex Based on the Trivacant Anion α‐[SiW9O34]10– – Synthesis, Structure and NMR Spectroscopy

“…Such a situation could strongly hamper the dynamic relaxation of the molecular framework and thus render slow the net H + hopping over the {Zr 3 nKeggin anions in aqueous solution in which the H + hopping over the {M 3 O 3 } cap was found to proceed more quickly. [26] The H + hopping frequency decreases further within the monoprotonated anion H 1 -1 since the 183 W resonances still broaden, until those attributed to the belt ulti- Figure 6. 183 W NMR spectra of H 3 -1 (a), H 2 -1 (b) and H 1 -1 (c) as Na + salts.…”

Multilayer Assemblies Consisting of Tri‐Vanadium‐Substituted Heteropolyanions and Its Electrocatalytic Properties

“…We can see that the redox peak with the formal potential E f at ca. 0.17 V should be assigned to the vanadium-centered one-electron redox process of P 2 W 15 V 3 [23]. Certainly, there are also tungstencentered redox waves at more negative potentials, which are beyond the aim of this article and not discussed further.…”

An Intriguing Morphology Evolution of Polyoxometalate‐Polystyrene Hybrid Amphiphiles from Vesicles to Tubular Aggregates

“…(Bu 4 N) 5 [H 4 P 2 W 15 V 3 O 62 ] was synthesized according to the method reported in ref. [51] The hybrid polymer, used here for further study, has a Dawson trivanadiumsubstituted heteropolytungstate head and PS chain denoted as Bu 4 N þ -POM-PS with molecular weight M n ¼ 86 000 g Á mol À1 . The details regarding the synthesis have been reported in our previous study.…”

“…Although the self-assembly of a POM-based hybrid for constructing POMfunctionalized structures has been extensively reported, [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] studies on POM-polymer hybrids are still scarce. Previously, we reported on the synthesis of a novel hybrid polymer composed of a POM head {(Bu 4 N) 5 [H 4 P 2 W 15 V 3 O 62 ]} and a polystyrene (PS) tail via ATRP.…”
