Studies of 1-hexyl-3-methyl-imidazolium ethylsulfate ([HMIM] EtSO 4 ) using an extended surface forces apparatus show, for the first time, an ordered structure within the nanoconfined ionic liquid (IL) between mica surfaces that extends up to ∼60 nm from the surface. Our measurements show the growth...
