Herein, we report on a three-component supramolecular hybrid system built from specific recognition processes involving Dawson-type polyoxometalate (POM), [P2W18O62]6–, cationic electron-rich cluster [Ta6Br12(H2O)6]2+, and γ-cyclodextrin (γ-CD). Such materials have been investigated using bottom-up approach by studying the interactions between γ-CD both types of inorganic units. Their ability to interact has in solid state single-crystal X-ray diffraction (XRD) solution multinuclear NMR...
In this communication, we report on a noteworthy hybrid supramolecular assembly built from three functional components hierarchically organized through noncovalent interactions. The one-pot synthesis procedure leads to the formation of large Mo-blue ring-shaped anion {Mo154}, which contains adduct based symmetric encapsulation Dawson-type [P2W18O62]6– by two γ-cyclodextrin units. Such nanoscopic onion-like structure, noted [P2W18O62]@2γ-CD@{Mo154} has been characterized single-crystal X-ray...
Metastable γ-Ga2O3 nanoflowers assembled from hexagonal nanopetals are successfully constructed by the oxidation of metallic Ga in acetone solution. The with a hollow interior structure exhibit short response time and large light-current–dark-current ratio under relatively low bias voltage, suggesting an especially important potential application solar-blind photodetection. As service to our authors readers, this journal provides supporting information supplied authors. Such materials peer...

Visible-light-driven plasmonic photocatalysts are promising candidates for environmental cleanup applications owing to their high solar energy utilization efficiency. In this Letter, we describe a facile and versatile cyclodextrin (CD)-driven colloidal self-assembly approach toward visible-light-responsive Au/TiO2 the degradation of herbicide phenoxyacetic acid (PAA) in water. The effect several cyclodextrins, natives modified, is investigated. Our results reveal that these cyclic...
[reaction: see text] Native and modified cyclodextrins (CDs) have shown polyvalent properties in a biphasic Pd/C-catalyzed Suzuki-Miyaura reaction. In addition to their mass transfer ability, the CDs favored dispersion of catalyst water. With randomly methylated (RaMe-beta-CD), gains initial activities were multiplied by factors between 3.8 343 depending on nature substrates. The reusability system was also demonstrated.
During these last years, cyclodextrins have contributed greatly to the development of catalytic processes in water. These cyclic oligosaccharides composed 6(α), 7(β) or 8(γ) glucopyranose units improve mass transfer aqueous-organic two-phase systems and are useful compounds design new catalysts. Thus, chemically modified can be used to: (i) increase significantly rate selectivity reactions catalyzed by water-soluble organometallic complexes, (ii) ligands for aqueous catalysis, (iii)...
During the past fifteen years, use of chemically modified cyclodextrins (CDs) in aqueous organometallic catalysis has significantly contributed to enlarge application field biphasic processes chemistry. In this paper, we describe how these supramolecular receptors became one most efficient solutions solve mass transfer problems catalysis. The scientific gaps that have been cleared explain exact role CDs systems are especially emphasized. particular, impact interactions between and...
Abstract A thermoregulated catalytic process has been elaborated using a ruthenium‐nanoparticle catalyst embedded into supramolecular cyclodextrin‐based hydrogel matrix. Upon heating, the gel phase turned sol in which alkenes could be efficiently hydrogenated. cooling, reaction products and metallic easily separated. The reusability of system was clearly demonstrated.
α-, β-, and γ-cyclodextrins (CDs) were modified on their secondary face by mechanosynthesis at room temperature using a laboratory-scale ball-mill. Mono-2-tosylated γ-CDs obtained in good yield from mixtures of native γ-CDs, respectively, N-tosylimidazole, an inorganic base, with each them being the solid state. The yields appeared to be dependent upon nature base reaction time. A kinetic monitoring (1)H NMR spectroscopy demonstrated that highest mono-2-tosyl-CDs measured KOH as very short...
