Complexation of Methyl Orange with ß-cyclodextrin: Detailed Analysis and Application to Quantification of Polymer-bound Cyclodextrin

Cyclodextrin modified niosomes to encapsulate hydrophilic compounds

“…The increase in EE for MO due to niosomes with b-CD can be attributed to the presence of a complex between MO:b-CD since the association constant for the inclusion complex MO : b-CD (1 : 1) is considerable, about 3000 M À1 (ref. 56) as was mentioned. In the same conditions MY is very insoluble in water even in the presence of cyclodextrin, so the amount of complex formed with the last compound is considerably lower than with MO.…”

Recognition mechanism of d- and l-tryptophan enantiomers using 2-hydroxypropyl-α- or β-cyclodextrins as chiral selectors

“…2 In several studies, the stability constant of the complex has been calculated to quantify the supramolecular interaction in solution between the organic guest and the cyclodextrin host. To obtain such information, several approaches have been described, such as isothermal titration calorimetry, 4 solubility diagrams 5 and multivariate analysis, 6 as well as Scott/Scatchard plots, which were applied to data obtained from UV absorption spectroscopy, 7 capillary electrophoresis (CE) 8 and high performance liquid chromatography (HPLC). 9 The stability constants could also be calculated from diffusion coefficient data obtained by diffusion ordered spectroscopy (DOSY) experiments.…”

A Liquid‐Crystal‐Based System for Differentiating Structurally Related Analytes

“…Corresponding to their molecular structure and shape, they acquire a unique ability of entrapping guest molecules in their internal cavity. As a result, a host‐guest complex is formed between cyclodextrins and guest molecules ,. Among the mentioned cyclodextrins, β‐CD is the most widely used as they are easily accessible due to its appropriate internal cavity diameter and high water‐solubility .…”
