“…[ 24 ] W-containing catalyst is an effective candidate for ODS methods owing to its intrinsic redox proprertie. [ 25 ] Here, we chose diphenyl sulphide (DPS) as a model compound, octane as a substitution for gasoline and UTNBs as the catalyst (details seeing Experimental Section). All the results are based on high-performance liquid chromatography (HPLC) measurements.…”

“…Thus, POM amphiphilic building blocks comprising long single-alkyl chain surfactants behave as a dual trap for both substrate molecule and oxidizing agent. 105 POM mesostructures comprising single alkyl chain surfactants (A1 to A4) exhibit enhanced catalytic efficiencies for oxidation of sulfides to sulfones (Fig. 14).…”

Polyoxometalates (POMs) are discrete anionic metal-oxide nanoclusters which exhibit unrivalled structural diversity, exceptional physical properties, and have many potential applications. Nonetheless, possessing high crystalline energy and hydrophilic nature, the assembly of POM clusters into rationally design architectures has been a long-standing bottleneck for their ultimate use in advanced materials and devices. To confront this challenge, both covalent and non-covalent modifications of POM nanoclusters are increasingly considered. This perspective reviews recent progress in the assembly of non-covalently modified surfactant-encapsulated POM nanoclusters with particular emphasis on our research work. The described solution-based assembly approach provides an excellent control on size, shape, and stability of the assembly structures. By effective exploitation of non-covalent interactions between the POM hybrid nanobuilding blocks, several unprecedented assembly structures including disks, cones, tubes, fullerene-like spheres, multiple shape flowers, wires, and thin films can be achieved. The assembly structures are highly robust and tunable in terms of size and shape and can act as hosts for guest nanomaterials to develop composite materials of combinatorial properties. In the last section of this manuscript, we present the catalytic properties of the assembly structures and their remote controlled manipulation in the reaction system.

“…1 Beyond the wellexplored small-molecule surfactants 2, 3 and block-copolymers [4][5][6][7] , giant surfactants have been regarded as a new kind of attractive topic because they contain functional (e.g., catalysis [8][9][10][11] , oxidize-reduction redox 12 or magnetic properties 13 ) inorganic nanoparticles/molecular clusters which simultaneously act as surfactant polar head groups. 14-22 They can self-assemble into order structures in bulk 23 , thin film 24 and solution 14,25,26 .…”

A series of multi-headed giant surfactants based on polystyrene (PS)-polyhedral oligomeric silsesquioxane(s) (POSS) conjugates, with a different number and topology of POSS heads, are found to self-assemble into different supramolecular structures including vesicles, cylindrical and spherical micelles in H2O/DMF mixed solvents. The transitions among different morphologies can be rationally controlled by tuning the number and topology of POSS heads, as well as the macromolecular concentration.
