ResumoPhotooxidation reactions on the solid films of naphthacene and rubrene were studied by Penning ionization electron spectroscopy (PIES) and UV photoelectron spectroscopy (UPS). PIES was found to reveal the processes of the surface reaction within the first layer selectively. On the other hand, the UPS result showed that the photooxidation reaction proceeded into the inner layers as oxygen molecules diffused into the solid. The present study indicates that the reaction process from the surface to the bulk can be effectively probed by a combination of PIES and UPS.
