      abstract     = {The growth of high-quality thin films is a key issue in the
                      ability to design electronic devices based on organic
                      materials and to tune their properties. In this context, the
                      interfaces between metals and organic films play a decisive
                      role. Here, we report on the interface formation between
                      copper-phthalocyanine (CuPc) and an Ag(111) surface using
                      various complementary methods. High-resolution low-energy
                      electron diffraction revealed a rich phase diagram for this
                      system with disordered (two-dimensional (2D)-gas-like) and
                      ordered structures (commensurate and point-on-line). In
                      particular, a continuous change in lattice parameters with
                      increasing coverage was found for long-range ordered
                      structures, indicating a substrate-mediated repulsive
                      intermolecular interaction similar to the case of
                      tin-phthalocyanine/Ag(111). Chemisorptivebonding to the
                      substrate was found by x-ray standing waves and ultraviolet
                      photoelectron spectroscopy, and this weakened with
                      increasing coverage at low temperature. This remarkable
                      effect is correlated to a shift in the highest occupied
                      molecular orbital (HOMO) and a HOMO-1 split off band to
                      higher binding energies. Based on our experimental results,
                      we present a comprehensive study of the adsorption behavior
                      of CuPc/Ag(111), including the mechanisms for phase
                      formation and molecular interaction.},
