• ], bithiophene–fluorenone conjugated oligomers [20], a 2,6-di(acetylamino)pyridine substituted conjugated module [21], and a molecular hexapod having a benzene core and six oligo(p-phenylene vinylene) legs [22]. The conformers can have an impact on the expression or suppression of chirality of the supramolecular

• interaction; large organic molecules; substrate–adsorbate interaction; supramolecular structure; Introduction It is well known that the formation of highly ordered 2D supramolecular networks on smooth surfaces, such as metal substrates or highly oriented pyrolytic graphite (HOPG), is mainly governed by the

• variations in that interaction, play a minor role. These interactions mainly determine the orientation of the resulting supramolecular structure with respect to the underlying substrate lattice [3][6][10][11][12][13][14]. This is mainly due to the fact that lateral variations in the interaction between the

• agreement with the experimental findings. These results illustrate the detail of microscopic understanding that can be extracted from combined STM experiments and state-of-the-art calculations. They also support the validity of structural concepts for the self assembly of supramolecular networks for cases

• on top of a substrate. This specific case is immediately generalized to the idea of depositing molecular, macromolecular or supramolecular organic species on top of inorganic platforms. By exploiting molecular self-organization, one finally arrives at a functional system with novel properties. Much
