Using metastable atom electron spectroscopy (MAES), changes of the outermost electronic states of organic thin films were measured for an OTi-phtalocyanine (OTiPc) film and a 8-bromooctanehtiol (8BrT) self-assembled monolayer (SAM) during the impact of slow He* (23S). Removal of the outermost atoms, i.e., oxygen atom for OTiPc film and for Br atom for 8BrT self-assembled monolayer (SAM), whose molecular orbitals spread to the outside of the film, can be successfully realized. In the case of 8BrT SAM, we also observed a new band related to the formation of a C=C double bond at the surface. The observed spectral changes in MAES indicate that the surface reaction can be realized by the selective ionization of the outermost surface with the impact of slow metastable atoms.
