Electronic structures of the ionic liquids formed by 1-buthyl-3-alkylimidazolium ion [C(n)mim](+) (n = 4, 8, 10) with fluorine-containing anions (tetrafluoroboronate BF4-, hexafluorophosphate PF6-) were studied by ultraviolet photoemission spectroscopy (UPS), inverse photoemission spectroscopy (IPES), and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. Comparison of the calculated density of states with the observed spectra has revealed that the energies of the molecular orbitals of these ionic liquids are significantly affected by the electrostatic Madelung potential among the ions, by which the top of the occupied states and the bottom of the unoccupied states are both derived from the cation.
