Figure 1.
F 1s region measured in 0° (left) and 80° (right) emission for the clean Ag(111) crystal (I), after deposition of 0.5 ML of [C8C1Im][Tf2N] (II), after two subsequent deposition steps of 0.6 ML of [C8C1Im][PF6] on top of the existing [C8C1Im][Tf2N] layer (III and IV), and after heating the layered system to 370 K for 20 min (V). All spectra have been measured at RT. At the top of the figure, the molecular structures of 1‐methyl‐3‐octylimidazolium hexafluorophosphate, [C8C1Im][PF6], and 1‐methyl‐3‐octylimidazolium bis[(trifluoromethyl)sulfonyl]imide, [C8C1Im][Tf2N] are shown.
