1H NMR Studies of Aqueous Micellar Solutions of N-Dodecyl- N,N-dimethyl-N-benzylammonium Chloride

Geminal Ionic Liquids: A Combined Approach to Investigate Their Three‐Dimensional Organisation

“…These cross-peaks probably suggest contact between the imidazolium ring and the alkyl chain. A similar observation has been previously reported for N-dodecyl-N,N-dimethyl-N-benzylammonium chloride in D 2 O, [19] and for 1-methyl-3-octylimidazolium bromide in D 2 O. [20] The presence of these cross-peaks seems to indicate that, at 298 K, the liquid structure of geminal IL 1 is governed not only by Coulomb interactions, but also by p-p stacking between imidazolium and the phenyl ring.…”

Static and dynamic light-scattering studies on micellar solutions of alkyldimethylbenzylammonium chlorides

“…Our previous data [20,21] indicate that introduction of this substituent results in an approximately two-fold decrease in the value of the cmc and a substantial increase in the degree of ionization, β, of the micelles. According to NMR results of Różycka-Roszak and Cierpicki [32], the benzyl group of dodecylbenzyldimethylammonium cation is located inside the micelle. Such a conformation may account for the high values of β.…”

Study of reverse micelles of di-isobutylphenoxyethoxyethyldimethylbenzylammonium methacrylate in benzene by nuclear magnetic resonance spectroscopy

“…5b). The cross peaks can be interpreted as a result of both intra-and intermolecular interactions between the respective fragments [17][18][19][20][21]26,27], as shown in Fig. 4.…”

“…4a and 4b, respectively. Unfortunately it is impossible to distinguish between inter-and intramolecular interactions for the particular system studied, which is often the case in such complex systems when correlations between molecules of the same kind are considered [19,26].…”
