• ]acridine-7,14-dione (quinacridone, QA), which forms 1D chains on flat metal surfaces already per se, on a vicinal Ag(100) surface. We describe how the presence of the step edges influences the azimuthal orientations of the chains. QA is a good candidate for such experiments because strong intermolecular

• described in several examples in the literature. Most often, flexible substituents on more rigid core units lead to different conformers, which self-assemble in different 2D structures as shown, e.g., for porphyrin [16], phthalocyanine [17], and quinacridone derivatives [18], N,N-diphenyl oxalic amide [19
