Michael Lepper presents a detailed room temperature scanning tunneling microscopy study of Nickel-tetraphenyltetrabenzoporphyrin on Cu(111), a prototype system for the fabrication of functional molecular architectures. The peculiar adsorption behavior, in particular the observation of three different coexisting supramolecular arrangements and the identification of two different intramolecular conformations within one arrangement, yield valuable insights into the specific molecular interactions and the self-assembly process in general.   Contents Fundamentals of Scanning Tunneling Microscopy Experimental Setup Coverage Dependent Adsorption Behavior of Ni-TPBP on Cu(111) Polymorphism of the Supramolecular Arrangements Intermolecular Interactions within the Supramolecular Arrangements Intramolecular Conformations  Target Groups Researchers and students in the fields of physical chemistry, surface science and molecular sciences Practitioners in these areas The Author Michael Lepper finished his Master Thesis under the supervision of PD Dr. Hubertus Marbach at the Chair for Physical Chemistry II of Prof. Hans-Peter Steinrück at the FAU Erlangen-Nürnberg, in which he is now working on his PhD thesis.
