The plot of the anion binding energy vs ε HOMO represents two linear dependencies (Figure , TfO -, and TFSI -. Like G bind (ε HOMO ), r 0 (ε HOMO ) for the anions also represents two dependencies (Figure G), while r 0 (ε LUMO ) is a linear relationship (Figure ). The strongest interaction with the solvent is observed for F -and the weakest onefor the TFSI -and PF 6 -anions.
