Towards Substrate-Independent Self-Assembling Monolayers: Investigation of Short Nylon Oligomers — •Manuela Pluntke¹, Sabine Letsche², Dirk Volkmer², and Othmar Marti¹ — ¹Institute of Experimental Physics, Ulm University, D-89069 Ulm, Germany — ²Institute of Inorganic Chemistry II, Ulm University, D-89068 Ulm, Germany

Self-assembled monolayers provide a convenient and simple route to tailor the surface properties of a material. Our current efforts are focussed on the design of molecules which form stable two-dimensional monolayers on a broad variety of substrate surfaces. This requires a robust and close packing of molecules in a two-dimensional layer in which the supramolecular entities are stabilized by hydrogen bonds. For that purpose we have synthesized short nylon oligomers with different functional groups (e.g. N,N'-Bis(isonicotinyl)-1,6-hexamethylendiamin) and we have investigated their self-assembly on mica by means of atomic force microscopy and STM.
