Thorough studies of tricyanomethanide-based ionic liquids - the influence of alkyl chain length of the cation.
The glassy, supercooled, and normal liquid states of the 1-alkyl-3-methylimidazolium tricyanomethanide series [CnC1im][TCM] (n = 2, 4, 6, 8, and 16) were investigated by dielectric and mechanical…

How the Structure of Pyrrolidinium Ionic Liquids Is Susceptible to High Pressure.
TLDR
The simulations predict that for 1-alkyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide, Pyrr1,n(+)/NTf2(-) with n = 8 and 10, the PO and CO fade when the external pressure increases from ambient pressure to 10000 bar, and observe that the apolar tail group as well as the polar group correlations are susceptible to the applied pressure.
Thermal and structural studies of imidazolium-based ionic liquids with and without liquid-crystalline phases: the origin of nanostructure.
TLDR
It is argued that the nanostructures of ILs are essentially the same as the layer structures in the LC phases.

Ionic liquid crystals: hexafluorophosphate salts
A series of novel hexafluorophosphate salts, based on N,N′-dialkylimidazolium and substituted N-alkylpyridinium cations, display liquid crystalline behaviour at temperatures above their melting…
Structure of ionic liquids of 1-alkyl-3-methylimidazolium cations: a systematic computer simulation study.
TLDR
Partial structure factors of 1-butyl- and 1-octyl- derivatives display a peak at a wave vector smaller than the main peak, indicating the occurrence of an intermediate range order in these ionic liquids due to the presence of long alkyl chains.
Nanostructural organization in ionic liquids.
TLDR
As the length of the alkyl chain increases, the nonpolar domains become larger and more connected and cause swelling of the ionic network, in a manner analogous to systems exhibiting microphase separation.

Physicochemical properties and structures of room temperature ionic liquids. 2. Variation of alkyl chain length in imidazolium cation.
TLDR
The alkyl chain length of 1-alkyl-3-methylimidazolium bis(trifluoromethane sulfonyl)imide was varied to prepare a series of room-temperature ionic liquids (RTILs), and the thermal behavior, density, viscosity, self-diffusion coefficients, and ionic conductivity were measured over a wide temperature range.
Nanoscale segregation in room temperature ionic liquids.
TLDR
This study provides the first experimental evidence of the existence of nanoscale heterogeneities in neat liquid and supercooled RTILs, such as 1-alkyl-3-methyl imidazolium-based salts, using X-ray diffraction, showing a behavior that resembles the density one only below the glass transition, thus suggesting a complex behavior above this temperature.
Ionic liquids: first direct determination of their cohesive energy.
TLDR
The results obtained in this study emphasize and constitute clear experimental support for the novel concept that these liquid salts are composed of polar and nonpolar domains; that is, they exhibit microphase segregation.
Thermodynamics, structure, and dynamics in room temperature ionic liquids: the case of 1-butyl-3-methyl imidazolium hexafluorophosphate ([bmim][PF6]).
TLDR
A strong connection between structure and dynamics is highlighted, showing the existence of three temperature ranges in the glassy state across which both the spatial correlation and the dynamics change, confirming the view that RTILs show a substantial degree of order.

TLDR
A model to perform coarse grained molecular dynamics simulations of room temperature ionic liquids of the family 1--alkyl-3-methylimidazolium hexafluorophosphate has been developed and Calculated structure factors demonstrate intermediate range ordering in these liquids.
