Inclusion complexes of 2-phenoxyethanol and alkoxyethanols in cyclodextrins: an 1H NMR study

NMR spectroscopic investigation of inclusion complexes between cyclodextrins and the neurotoxin tetramethylenedisulfotetramine

“…Armed with these initial insights, we pursued the determination of the binding constant K between TETS and the CyDs studied herein via titration experiments using NMR. This approach has found tremendous success in the determination of binding constants for inclusion complexes formed between a variety of organic compounds and CyDs . NMR titration experiments were not conducted for the TETS : α ‐CyD case because no observable changes in the TETS's protons chemical shift upon incubation with the CyD were identifiable.…”

Complexation of hydroxytyrosol with β-cyclodextrins. An efficient photoprotection

“…The intercept with the axial axis, 1/K a Dd c , gave an averaged association constant K a ¼93AE7 M À1 , calculated from the three aromatic protons. Considering a 300 MHz spectrometer and the value of Dd c , the fastexchange condition 16 for obtaining only one set of signals involves that the inclusion and release of the guest molecule must occur at least 63 times/s.…”

Micellar behavior of aqueous solutions of dodecyldimethylethylammonium bromide, dodecyltrimethylammonium chloride and tetradecyltrimethylammonium chloride in the presence of α-, β-, HPβ- and γ-cyclodextrins

“…1 H NMR spectroscopy helps in studying the interactional behavior of the components [5,[38][39][40][41]. To gain more insight into the interaction between the two moieties, 1 H NMR for all the three-surfactant systems in the absence and presence of different cyclodextrins were recorded (see Figs.…”
