Publikation Supramolecular patterned surfaces driven by cooperative assembly of C60 and porphyrins on metal substrates(Wiley, 04.09.2004) Bonifazi, Davide; Spillmann, Hannes; Kiebele, Andreas; de Wild, Michael; Seiler, Paul; Cheng, Fuyong; Güntherodt, Hans‐Joachim; Jung, Thomas; Diederich, FrançoisPlenty of room on top: Unprecedented one- and two-dimensional fullerene patterns were obtained upon evaporation of pristine C60 onto pre-organized porphyrin monolayers on silver surfaces following a bottom-up approach. The arrangement of the fullerene molecules on the patterned layer can be controlled by the porphyrin structure (see scanning tunneling microscopy images).01A - Beitrag in wissenschaftlicher ZeitschriftPublikation A novel route to molecular self-assembly. Self-intermixed monolayer phases(Wiley, 18.10.2002) de Wild, Michael; Berner, Simon; Suzuki, Hitoshi; Yanagi, Hisao; Schlettwein, Derck; Ivan, Stanislav; Baratoff, Alexis; Guentherodt, Hans-Joachim; Jung, Thomas A.The stars and stripes: A novel route to highly perfect molecular self-assembly is presented. Depending on the relative surface (Ag(111)) coverage of the two species, subphthalocyanine and C60 (green and yellow in the colored STM image) on an surface, well-ordered intermixed monolayers consisting of 1D chains with 1 nm width or 2D hexagonal patterns are formed. The structural parameters and schematic binary "phase diagram" of this system are deduced from detailed room-temperature STM studies. The most important underlying interactions and the relevant properties of the molecules are discussed qualitatively.01A - Beitrag in wissenschaftlicher Zeitschrift
