Abstract: The electronic structure of the interface between cyclooctatetrene(COTH) and Ru metal is studied by the ultraviolet photoelectron spectroscopy(UPS). Three peaks are observed at 5.6, 7.9 and 10.2 eV below the Fermi level, they are related to the πCC, σCC and σCH bands of the phenyl in the COTH material respectively. The peak at 3.8 eV below the Fermi level is related to the C-C band with π characteristic orbit derived from the COTH containing eight phenyls. The highest occupied state (HOS) of COTH is at 1.8 eV below the Fermi level. The work function of COTH is only 3.2 eV, 1.0 eV lower than that of clean Ru. The results of the angle resolved ultraviolet photoelectron spectroscopy (ARUPS) suggest that the molecule of COTH is approximately parallel to the substrate surface.
