| Outline of Final Research Achievements |
In order to realize the molecular electronic devices consisting of a small amount of functionalized molecules, the exact understanding of interactions between molecules and electrodes is of importance. In this study, we first focused on the dynamics of photoexcited electronic states for functionalized self-assembled monolayers (SAMs). The photoexcited processes was measured using time-resolved two-photon photoemission (TR-2PPE) spectroscopy, and then the interactions between the excited functional groups and the metal substrate were quantitatively elucidated as a function of their distance. By the analysis of the experimental results, the dominant decay process was attributed to the excitation energy transfer. In addition, in the search for creating multi-functional molecular layers, we successfully fabricated the self-assembled heterogeneous bilayer systems.
