X-ray photoelectron study of fluorinated graphite intercalation compounds

Intercalated compounds of fluorinated graphite C2F . yR, where R is benzene , hexafluorobenzene, acetone, or germanium tetrachloride, are studied by X- ray photoelectron spectroscopy. The binding energies of the C1s and F1s inn er levels indicate that the C-F chemical bond in fluorinated graphite diffe rs dramatically front the covalent bond in graphite monofluoride. The bindi ng energies of the inner levels in atoms of the graphite fluoride matrix an d GeCl4 are analyzed and it is concluded that there is no chemical binding between the host matrix and the guest molecule.
