      abstract     = {The understanding of growth mechanisms and electronic
                      properties is a key issue for improving the performance of
                      small organic devices, in which the metal-organic interface
                      and its properties play a crucial role. In this context we
                      investigated the adsorption behavior and the electronic
                      properties of copper-II-phthalocyanine (CuPc) within the
                      first adsorbate layer on Au(111) and Cu(111). Together with
                      recent results published for CuPc/Ag(111) [Kroger et al.,
                      New J. Phys. 12, 083038 (2010)] this leads to a
                      comprehensive understanding of the adsorption of CuPc on
                      noble metal surfaces: On Cu(111) the molecule-surface
                      interaction is the strongest. The molecules chemisorb on the
                      surface and form one-dimensional chains or two-dimensional
                      islands, depending on coverage. This behavior indicates an
                      attractive intermolecular interaction. In contrast, on
                      Au(111) CuPc is only weakly physisorbed and behaves like a
                      two-dimensional gas in a wide coverage regime. Only when
                      densely packed do the molecules form ordered structures,
                      which are scarcely influenced by the structure of the
                      metallic surface. Molecule-molecule interaction is also very
                      weak, but in contrast to CuPc on Ag(111) no clear
                      indications for a repulsive interaction are found. Regarding
                      the adsorption strength, this latter system represents an
                      (possibly unique) intermediate case which enables the
                      unusual intermolecular repulsion found recently. Our results
                      highlight the special role of this model system, since the
                      interaction of CuPc with the metal can be "tuned" in any
                      order of the adsorption scenarios observed by selecting the
                      right substrate material.},
