Molecular Dynamics of Deep Eutectic Solvents
Summary
Deep eutectic solvents (DESs) are designer liquids formed by mixing hydrogen‐bond donors and acceptors, which exhibit melting points significantly lower than those of their pure components. Molecular dynamics simulations have become indispensable for elucidating the microscopic origins of their unique physicochemical properties—namely high solvation power, tunable viscosity and remarkable thermal stability. Atomistic and coarse‐grained models have characterised the intricate hydrogen‐bond networks, ion pairing and nanoscale segregation that drive DES behaviour, while enhanced sampling and refined force fields have improved agreement with experimental scattering and spectroscopic data. These studies reveal how temperature, water content and component ratio govern structural rearrangements, transport properties and interfacial phenomena. By linking simulation and experiment, researchers are designing DESs for sustainable catalysis, metal electrodeposition, biomass processing and pharmaceutical solubilisation, underlining their global significance as green alternatives to volatile organic solvents.
