      abstract     = {One of the challenges in molecular electronics is to design
                      molecules which can be used as functional units in
                      electronic devices. The subject of our investigations is an
                      asymmetrical molecule,
                      dihydroxy(4-thiomorpholinomethyl)benzoic acid (TMBA), whose
                      structural and electronic properties are characterized. The
                      self-assembly behavior of TMBA on Au(111) surfaces resulting
                      in highly ordered monolayers is obtained using scanning
                      tunneling microscopy (STM). Furthermore, investigations on
                      the electronic properties of the combined metal/molecule
                      system reveal an orbital mediated tunneling process and
                      tunneling decay constants for the carboxylic and
                      thiomorpholino group. Thus, a diode-like character of TMBA
                      is shown to be caused by intrinsic electronic properties of
                      different molecular moieties.},
