【Abstract】 The electronic structure、thermal stability and molecule orientation of 5-(N-n-butyl-3,4,9,10-perylene tetracarboxyl icimide-N’-phenyl)-10, 15, 20-triphenylporphyrin growth on Ru(0001) surface has been studied with ultraviolet photoemission spectroscopy. Three emission features of the organic material are observed at 4.5, 6.8 and 9.2 eV respectively, and the HOS is located at 1.5eV below the Fermi level. The decomposition of the adsorbed organic substance on Ru(0001) surface is at roughly 200℃. The angle-resolved ultraviolet photoemission spectroscopy results suggest that the two condensed nuclei which compose the organic material, porphyrin and perylene, are not in the same plane. There exists an angle between these two planes of the condensed nucleus, one plane is not parallel to the substance.更多还原
