      abstract     = {Self-assembled monolayers (SAMs) of ruthenium-based
                      molecular wires on solid surfaces are of great interest for
                      optoelectronic and nanoelectronic applications. Here, we
                      present a novel reactive Ru precursor, which enabled us to
                      grow SAMs of Ru complex wires on Au surfaces even at room
                      temperature. Thus, the Ru complex wire growth can be
                      performed easily by sequential reaction of the reactive Ru
                      precursor with terpyridine ligands without the harsh
                      reaction conditions needed otherwise. Subsequently, we
                      monitored the stepwise growth using infrared reflection
                      absorption spectroscopy (IRRAS) and surface-enhanced Raman
                      spectroscopy (SERS). A comparison of IRRAS and SERS data
                      with theoretical spectra, derived from density functional
                      theory calculations, enabled us to verify the formation of
                      each individual growth step. Furthermore, we used these data
                      to determine the orientation of the Ru-based molecular wires
                      with respect to the Au surface. Growth step-dependent layer
                      thicknesses obtained from variable angle spectroscopic
                      ellipsometry verify the spectroscopic results. Thus, we
                      provide a room-temperature method to realize Ru complex wire
                      growth based on a reactive Ru precursor.},
