Candidates for molecular nanowires for the interconnection of gold nanoelectrodes in a molecular‐scale electronic device are to be found in end‐functionalised poly( para ‐phenyleneethynylene)s. The self‐assembly of these polymers was studied on atomically flat solid substrates. On graphite, sub‐molecularly resolved imaging with scanning tunneling microscopy revealed nanorods in a 2 D nematic‐like texture, while on mica, scanning force microscopy (see picture) shows that the nanorods can self‐assemble into highly oriented micrometer‐long nanoribbons with a molecular cross‐section.
