The properties of ILs can be tailored by the selection of specific anions and cations. A common feature of ILs composed of cations with long aliphatic side chains are heterogeneities on the nanometer length scale. This so-called microphase separation arises from the clustering of aliphatic moieties. We used small angle neutron and x-ray scattering to study the liquid structure in a series of [Cn C1 im] + based ILs with different anions. Analysis of the scattering pattern shows that the structural heterogeneities are governed by the interplay between the alkyl chain length and the geometry of the anion.
