Adsorption geometry and stability of organic molecules on surfaces are key parameters that
determine the observable properties and functions of hybrid inorganic/organic systems …

Using light to control the switching of functional properties of surface-bound species is an
attractive strategy for the development of new technologies with possible applications in …

We review the binding and energy level alignment of π-conjugated systems on metals, a
field which during the last two decades has seen tremendous progress both in terms of …

Using scanning tunneling spectroscopy, we study the transport of electrons through C 60
molecules on different metal surfaces. When electrons tunnel through a molecule, they may …

Direct comparative studies of the photoisomerization of azobenzene derivatives in self-
assembled adlayers on Au and as free molecules in dichloromethane solution were …

We present a detailed comparison of the S0, S1 (n→ π*) and S2 (π→ π*) potential energy
surfaces (PESs) of the prototypical molecular switch azobenzene as obtained by Δ-self …

Coinage metal adsorbed azobenzene is investigated as prototypical molecular switch. It is
shown that switching capabilities are not just lost due to excited state quenching, but already …

We use time-resolved two-photon photoemission to study two molecular photoswitches at
the Au (111) surface, namely azobenzene and its derivative tetra-tert-butyl-azobenzene …

Modifying surface-bound molecular switches by adding side groups is an established
concept for restoration of functionality which a molecule possesses in solution and which is …

Time-and angle-resolved two-photon photoemission (2PPE) spectroscopies have been
used to investigated the electronic structure, electron dynamics and localization at the …
