Effect of replacing [NTf₂] by [PF₆] anion on the [BMIm][NTf₂] ionic liquid confined by gold

The effect of replacing bis(trifluoromethylsulphonyl)imide ([NTf2]) by hexafluorophosphate ([PF6]) in room temperature ionic liquid (IL) 1-butyl-3-methylimidazolium bis(trifluoromethylsulphonyl)imide ([BMIm][NTf2]) confined between two gold interfaces is herein reported through molecular dynamics simulations using all-atom non-polarisable force-fields. Five systems were studied ranging from pure [BMIm][NTf2] to pure [BMIm][PF6], with [PF6] molar...
