Different investigations, suchas 1D and 2D NMR spectroscopy, resonancelight scattering spectroscopy andmolecular dynamics simulations, havebeen jointly used to achieve a deeperunderstanding of the degree of structuralorder in two geminal ionic liquids.In particular, 3,3’-di-n-butyl-1,1’-(1,3-phenylenedimethylene)diimidazoliumand 3,3’-di-n-butyl-1,1’-(1,4-phenylenedimethylene)diimidazolium bis-ACHTUNGTRENUNG[bis(trifluoromethanesulfonyl)imide]have been studied. These geminal ionicliquids were chosen because of thepresence of both a rigid phenylenedimethylenelink between two imidazoliumrings, which should give a highdegree of order to the solvent system,and the different shapes of the two cationsof the isomers, which could inducedifferent properties and packing in theliquid state. Data collected here showthat the two geminal ionic liquids arecharacterised by a different degree ofstructural order that induces, for example,a different sensitivity of the twosolvent systems to temperature changesor to the presence of a co-solvent suchas methanol.
