Fluorescence resonance energy transfer (FRET) from the excited state of donor to ground acceptor is one most important fluorescence mechanisms and has wide applications in light-harvesting systems, light-mediated therapy, bioimaging, optoelectronic devices, information security fields. The phenomenon sequential natural photosynthetic systems provides great inspiration for scientists make full use light energy. In recent years, discrete supramolecular assemblies (DSAs) have been successively...
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...
During the past twenty years, cyclodextrins (CDs) have proven to be very effective in aqueous biphasic catalysis. They could act as molecular receptors for numerous organic substrates and favour their conversion at aqueous/organic interface. Recently, new applications been found CDs can now defined polyfunctional entities between substrate-containing phase catalyst-containing phase. In this paper, we highlight latest breakthroughs use of catalysis through several examples from literature.
A novel halloysite-hydrochar nanocomposite has been prepared and applied for the immobilization of Pd NPs to furnish an efficient catalyst hydrogenation nitroarenes. It was confirmed that use a catalytic amount β-cyclodextrin (β-CD) could improve yield reaction significantly. With aim investigation effect combination Hal Char, Char surface modification, way β-CD on activity, several control catalysts were their activities compared with catalyst. Hal-Char as support more effective than each...
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...

The selective dehydrogenation of aqueous solutions HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence different monoaryl-biaryl or alkyl-biaryl phosphines aryl diphosphines bearing sulfonated groups. All catalytic systems were used water without any additives proved be active at 90 °C, giving high conversions good TOF values. As an alternative Ru(II) metal precursor, known dimer [Ru(η6-C6H6)Cl2]2 was also tested...

At the boundary between mechanochemistry, supramolecular chemistry and catalysis, present study explores role of cyclodextrins (CDs) other saccharide additives in mechanosynthesis gold nanoparticles (AuNPs) their use as catalysts reduction substituted nitrobenzene derivatives.
Cyclodextrins (CDs) can be envisaged to cure some diseases related the brain, but behavior of these compounds toward blood-brain barrier (BBB) remains largely unexplored envisage such clinical applications. To fulfill this gap, toxicity and endothelial permeability for native, methylated, hydroxypropylated α-, β-, γ-CDs have been studied on an in vitro model BBB. As shown by sucrose immunofluorescence stainings, native CDs are most toxic (α- > β- γ-CD). Whereas chemical modification β-CD...
