Structure and Molecule-Substrate Interaction in a Co-octaethyl Porphyrin Monolayer on the Ag(110) Surface

Our results indicate that in the single molecular layer each molecular macrocycle is tilted with respect to the metal surface by about 15°. The strong molecular interaction with the substrate leads to the electron transfer from the metal to the molecule. The direct interaction with the substrate involves mostly the Co metal center.

The morphological and electronic properties of the Co-octaethylporphyrin (Co-OEP) / Ag(110) interface were studied by means of scanning tunneling microscopy (STM), near-edge X-ray adsorption fine structure  (NEXAFS) spectroscopy, ultraviolet photoemission spectroscopy (UPS), and density functional theory calculations (DFT). Our results indicate that in the single molecular layer each molecular macrocycle is tilted with respect to the metal surface by about 15°. The strong molecular interaction with the substrate leads to the electron transfer from the metal to the molecule. The direct interaction with the substrate involves mostly the Co metal center.
