      abstract     = {This work investigates the geometric and chemical
                      properties of different moleculemetal interfaces, relevant
                      to molecular electronics and functional surfaces
                      applications, by means of the normal incidence x-ray
                      standing wave (NIXSW) technique. All NIXSW data are analysed
                      by means of the newly developed open-source program
                      Torricelli, which is thoroughly documented in the thesis. In
                      order to elucidate the role played by the substrate within
                      molecule-metal interfaces, the prototype organic molecule
                      3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA) on the
                      Ag(110) surface is investigated. The molecule results more
                      distorted and at smaller bonding distances on the more
                      reactive Ag(110) surface, in comparison with the
                      Ag(100)$^{1}$ and the Ag(111)$^{2}$ substrates. This
                      conclusion follows from the detailed molecular adsorption
                      geometry obtained from the differential analysis of both
                      carbon and oxygen atoms. Subsequently, the chemisorptive
                      PTCDA/Ag(110) interaction is tuned by the codeposition of an
                      external alkali metal, namely K. As a consequence, the
                      functional groups of PTCDA unbind from the surface, which,
                      in turn, undergoes major reconstruction. In fact, the
                      resulting nanopatterned surface consists of alternated up
                      and down reconstructed Ag terraces covered by PTCDA
                      molecules partly unbound with respect to the pure molecular
                      phase. Within the context of the functional surfaces, the
                      interaction of the molecular switches azobenzene (AB) and
                      3,3,5,5-tetra-tert-butyl-azobenzene (TBA) adsorbed on the
                      Ag(111) surface is investigated. The bonding distance of
                      TBA, only slightly greater compared to AB, indicates that
                      the desired geometric decoupling of the photochromic moiety
                      to enable the switching in the adsorbate state does not
                      occur.$^{3}$ In [...]},
