Onionlike Hybrid Assemblies Based on Surfactant‐Encapsulated Polyoxometalates

Aqueous synthesis of mesostructured BiVO4 quantum tubes with excellent dual response to visible light and temperature

“…3(d)), mainly due to the associated reduction in surface energy [16], with a concomitant rearrangement of oleate ions on the surface of the BiVO 4 pearl-necklace-shaped quantum wires. Previous studies of the rearrangement of surfactant ions on the surface of polyoxometalates [17,18] support our suggestion of oleate ion rearrangement on the surface of the BiVO 4 pearl-necklace-shaped quantum wires. As the BiVO 4 has three surface oleate ligands, it may be expected that the forces generated when BiVO 4 pearl-necklace-shaped quantum wires come into contact with each other result in the rearrangement of the oleate ions on the BiVO 4 surface leading to a Y-shaped arrangement-one oleate ion moves in one direction while the other two move in the opposite direction along the planes perpendicular to the pearlnecklace-shaped quantum wires (Scheme 1(d)).…”

“…When the Y-shaped arrangements of oleate ions are aligned in the same direction, their mutual repulsion-coming from the direction of the pair of oleate ions-will inevitably force the side-to-side assembly of the pearl-necklace-shaped quantum wires to tilt a certain angle [17,19], thus, making them gradually assemble into tubular nanostructures (Scheme 1(d) and 1(e)). Published reports of the formation of tubular or spherical shapes by polyoxometalates with three or four surfactant ions further support our assumption that the BiVO 4 quantum tubes are formed because of the specific number of oleate ions attached and their peculiar rearrangement [17,18]. As shown in Fig.…”

Insights into the working mechanism of cathode interlayers in polymer solar cells via [(C8H17)4N]4[SiW12O40]

“…41. It is worth noting that the synthesis procedures of TASiW-12 are simple, green, and of high-yield and low-cost.…”

Smart Self‐Assemblies Based on a Surfactant‐Encapsulated Photoresponsive Polyoxometalate Complex

“…[7][8][9] Self-assemblies for all organically modified POMs with different morphologies have proved to be feasible, [8b] but up to now none of them can carry out a dynamic transition. Therefore, the fabrication of novel aggregate structures and smart POM assemblies will be of topical interest.…”
