ABSTRACT
Conformational variations of a 10 nm long oligothiophene wire comprising 24 thiophene rings on Au(111), which are related to the various straight and bent shapes of the long wires, have been directly visualized by scanning tunneling microscopy (STM). The local bending angles within the wire are well characterized as s-cis/s-trans configurations of individual thiophene rings. We find that the partial stabilization of the metastable s-cis conformation results in the wire bending, which should be influenced by solvent and substituents.
