PEG-Infiltrated Polyoxometalate Frameworks with Flexible Form-Factors

[Image: see text] We present the synthesis of metal oxide frameworks composed of the Preyssler anion, [NaP(5)W(30)O(110)](14–), bridged with transition-metal cations and infiltrated with polyethylene glycol. The frameworks can be dissolved in water to form freestanding rigid or flexible films or gel...

description [Image: see text] We present the synthesis of metal oxide frameworks composed of the Preyssler anion, [NaP(5)W(30)O(110)](14–), bridged with transition-metal cations and infiltrated with polyethylene glycol. The frameworks can be dissolved in water to form freestanding rigid or flexible films or gels. Powder X-ray diffraction shows that all form-factors maintain the short-range order of the original crystals. Raman spectroscopy reveals that, similar to hydrogels, the macroscopic mechanical properties of these composites are dependent on the water content and the extent of hydrogen-bonding within the water network. The understanding gained from these studies facilitates solution-phase processing of polyoxometalate frameworks into flexible form factors.
