Surface induced smectic order in ionic liquids - an X-ray reflectivity study of [C22C1im]+[NTf2].
Surface induced smectic order was found for the ionic liquid 1-methyl-3-docosylimidazolium bis(trifluoromethlysulfonyl)imide by X-ray reflectivity and grazing incidence scattering experiments. Near the free liquid surface, an ordered structure of alternating layers composed of polar and non-polar moieties is observed. This leads to an oscillatory interfacial profile perpendicular to the liquid ...

متن کاملNear-Wall Molecular Ordering of Dilute Ionic Liquids
The interfacial behavior of ionic liquids promises tunable lubrication as well as playing an integral role in ion diffusion for electron transfer. Diluting the ionic liquids optimizes bulk parameters, such as electric conductivity, and one would expect dilution to disrupt the near-wall molecular ordering. We study this ordering in the ionic liquids [Emim]+[NTf2]-, [Emim]+[DCA]-, and [C4mpyr]+[N...
متن کاملRelationship between low-Q peak and long-range ordering of ionic liquids revealed by high-energy X-ray total scattering.
The structures of 1-alkyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide ([CnmIm(+)][TFSA(-)]) ionic liquids (alkyl-chain length n = 4, 8, 10, and 12) have been studied by high-energy X-ray total scattering at T = 298-453 K. The low-Q peaks observed in the X-ray structure factors S(Q)s at 0.2 < Q < 0.4 A(-1) for n≤ 8 were almost unchanged up to T = 453 K, whereas they shifted to lower Q...
متن کاملNanoscale heterogeneity in alkyl-methylimidazolium bromide ionic liquids.
High-energy x-ray diffraction measurements and atomistic molecular dynamics (AMD) numerical simulations have been carried out on 1-alkyl-3-methylimidazolium bromide ionic liquids, C(n)mimBr, with n = 2, 4, and 6. Excellent agreement between experiment and simulation is obtained, including the region of the low-Q peak that has proved problematic in previous work in the literature. In the partial...
