Outline of Final Research Achievements

The mechanism of charge-transfer (CT) state formation at organic/metal interfaces was investigated by using synchrotron radiation based-angle resolved ultraviolet photoelectron spectroscopy. We found that diindenoperylene (C32H16) adsorbed on Ag(111) and Cu(111) showed CT states due to the CT from the metals to the unoccupied states of DIP, irrespective to the crystallinity and surface plane of the substrates, molecular orientation of DIP. By employing other organic molecules, it was implied that a key for the formaton of the CT states is a chemical structure that satisfies the Huekele's rule.
