abstract = {The solvation and the dynamic properties of apolar model
solutes in alkyl imidazolium-based ionic liquids (IL) are
studied by using all-atom molecular dynamics simulations. In
regards to specific IL effects, we focused on the often used
1-ethyl-3-methyl imidazolium cation in combination with the
anions tetrafluoroborate, acetate, and
bis(trifluoromethanesulfonyl)imide. Our findings reveal that
the size of the anion crucially influences the accumulation
behavior of the cations, which results in modified IL
solvation properties. Deviations between the different alkyl
imidazolium-based IL combinations can be also observed with
regard to the results for the radial distribution functions,
the number of surrounding molecules, and the molecular
orientation. The analysis of the van Hove function further
shows pronounced differences in the dynamic behavior of the
solutes. The simulations verify that the solute mobilities
are mainly influenced by the composition of the local
solvent shell and the properties of the underlying
Lennard–Jones interactions. Additional simulations with
regard to modified short-range dispersion energies for alkyl
imidazolium-based ILs validate our conclusions.},
