Abstract:
Transport of electrons through molecular units is an important topic in the field of molecular electronics (1) and future device modeling. Most of the research (2) has focused on saturated aliphatic chains or on ring structures with saturated C-C bonds, and only few theoretical papers and experiments have dealt with conjugated molecular bridges. All the theoretical work has addressed molecular bridges in ultra-high-vacuum (UHV), whereas all the previous measurements have been performed in a solvent environment. We report here on transient absorption experiments in UHV that probed heterogeneous electron transfer from the molecular chromophore perylen via different molecular anchor - bridge groups into nm-structured anatase TiO2 layers
