Table S1: Different transition temperatures observed for the ionic liquids studied in this work. TC, and Tm, refer to the temperature of formation and melting of a crystal or a liquid crystal phase, respectively, as observed in the thermal conductivity and DSC data. For liquids (4) to (8) the crystals nucleate within a glassy phase, as obtained also from POM experiments and explained in the text. Tg, refers to the formation of the glass, also obtained from thermal conductivity and DSC. The numbers in the first column identify the different ionic liquids, as follows: (1) 1-Ethyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide; (2) 1-Ethyl-3-Methylimidazolium bis(trifluoromethylsulfonyl)imide; (3) 1-Butyl-3-Methylimidazolium triflate; (4) 1-Ethyllimidazolium bis(trifluoromethylsulfonyl)imide; (5) 1-Butyl-3-Methylimidazolium nitrate; (6) 1-Ethyl-3-Methylimidazolium acetate.
