Abstract
The structural properties of three deep eutectic solvents (DESs), namely a 1:2 mixture of urea and choline (Ch) chloride and two analogous DESs containing different cations in place of choline, namely benzyl(2-hydroxyethyl)dimethylammonium (BeH) and benzyltrimethylammonium (Be), were studied by means of Molecular Dynamics simulations. The presence or not of a hydroxyl group on the organic cation, as well as of a bulky substituent such as the benzyl one, was found to strongly affect the DES hydrogen bond network, giving rise to different three dimensional arrangements of all the species present in the systems.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
