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...
A new deep eutectic solvent (DES), based on a methylated-β-cyclodextrin and levulinic acid, exhibiting supramolecular properties is presented here for the first time.
The complexation abilities of five cyclodextrins (CDs) with seven phenylpropanoids (PPs) were evaluated by UV–visible spectroscopy, phase solubility studies and molecular modeling. Formation constants ( K f ), efficiency (CE), PP:CD molar ratio, increase in formulation bulk energy assessed. All complexes exhibited a 1:1 stoichiometry but their stability was influenced the nature position phenyl ring substituents. A relationship between intrinsic guests S 0 ) solubilizing potential CD...
Carvacrol and thymol have been widely studied for their ability to control food spoilage extend shelf-life of products due antimicrobial antioxidant activities. However, they suffer from poor aqueous solubility pronounced flavoring that limit application in systems. These drawbacks could be surpassed by encapsulation cyclodextrins (CDs). Applications inclusion complexes with CDs were reported without investigating the phenomenon deep. In this study, characterized terms formation constants (...
The chaotropic character of Keggin-type polyoxotungstate anions was evaluated with respect to their ability bind γ-cyclodextrin (γ-CD) by varying the global charge density nanometer-sized polyanion.
The complex formation between daclatasvir and γ-CD or heptakis(2,3,6-tri-O-methyl)-β-CD (TM-β-CD) was studied by isothermal titration calorimetry molecular modeling. Both techniques supported the predominant of a 2:1 in case although 1:1 may be formed to much lower extent as well. In TM-β-CD stoichiometry exclusively 1:1. Complex with did not require dissociation dimer, which is present solution, resulted binding constant 1.67·107 M-2. contrast, weak (K = 371 M-1) required dimer. This line...
The self-assembly of organic amphiphilic species into various aggregates such as spherical or elongated micelles and cylinders up to the formation lyotropic hexagonal lamellar phases results from cooperative processes orchestrated by hydrophobic effect, while those involving ionic inorganic polynuclear entities nonionic components are still intriguing. Herein, we report on supramolecular behavior giant toroidal molybdenum blue-type polyoxometalate, namely, {Mo154} in presence...
The inclusion of volatile derivatives benzene and cyclohexane in β-cyclodextrin (β-CD), hydroxypropyl-β-CD, hydrophilic β-CD-thioethers was investigated by static headspace gas chromatography (HS-GC) molecular modelling. obtained binding constants strongly increase with the amount space filling CD cavity salt concentration. β-CD thioethers show a 3-10 times higher potential than native β-CD.
Supramolecular host–guest inclusion complexes based on cyclodextrins (CDs) are generally studied in aqueous solutions or more rarely the presence of a cosolvent. In this study, we investigate for first time ability CDs to retain their properties deep eutectic solvents (DESs). Five were solubilized mixtures choline chloride:urea (ChCl:U), and these new characterized by measuring viscosity density as function temperature. The heat dissolution β-CD ChCl:U was measured calorimetry. process is...
Abstract Water‐soluble salts of anionic [Re 6 Q 8 (CN) ] 4− (Q=S, Se, Te) chalcogenide octahedral rhenium clusters react with γ‐cyclodextrin (γ‐CD) producing a new type inclusion compounds. Crystal structures determined through single‐crystal X‐ray diffraction analysis revealed supramolecular host–guest assemblies resulting from close encapsulations the cluster within two γ‐CDs. Interestingly, nature inner ligands influences strongly conformation. The S interacts preferentially primary faces...
Hydrogenation of arene derivatives can be successfully performed in water by using ruthenium(0) nanoparticles stabilized 1 : inclusion complexes formed between methylated cyclodextrins and an ammonium salt bearing a long alkyl chain.
