TL;DR: In this article, a simple way to prepare cucurbit[5]uril is described, and the solubility of cucurbits in aqueous acids has been investigated by means of calorimetric titrations.
Journal ArticleDOI
Complexation of Some Amine Compounds by Macrocyclic Receptors
TL;DR: In this paper, some aspects of complexformation, liquid-liquid extraction, and transport through liquid membrane of various amine compounds like ammonium ion, amines, amino acids and peptides, withmacrocyclic receptors, such as crown ethers,cryptands, calixarenes, and cucurbituril are presented.
Journal ArticleDOI
Complex Formation between Cucurbit[n]urils and Alkali, Alkaline Earth and Ammonium Ions in Aqueous Solution
TL;DR: In this paper, the authors examined the complex formation between cucurbit[5]uril, decamethylcucurbit [5]-uril and cucurbitsuril in aqueous solution and calculated the stability constants of the complexes formed without the knowledge of the exact solubility of the ligand.
Journal ArticleDOI
The determination of complex stabilities between different cyclodextrins and dibenzo-18-crown-6, cucurbit[6]uril, decamethylcucurbit[5]uril, cucurbit[5]uril, p-tert-butylcalix[4]arene and p-tert-butylcalix[6]arene in aqueous solutions using a spectrophotometric method
TL;DR: In this paper, the stability constants of the complexes formed are determined from UV-spectrophotometric measurements, even without the knowledge of the molar absorptivities and of the solubilities of the guest molecules.
Journal ArticleDOI
Cucurbituril and α- and β-Cyclodextrins as Ligands for the Complexation of Nonionic Surfactants and Polyethyleneglycols in Aqueous Solutions
TL;DR: In this paper, the complexation of nonionicsurfactants and polyethylene glycols by the ligandscucurbituril, α- and β-cyclodextrin was studied in aqueous solution.
