Mono-Substituated 4,4'-dimethyl-2,2'-bipyridine Ligands at the Solid-Liquid Interface: Study of the Molecular Organization

Höppener, Stephanie; Marin, Veronica; Schubert, Ulrich S.

Abstract:

Molecular organization has an important influence on the performance of organic materials, i.e. solar cells, light emitting diodes or sensors. 4,4'-Dimethyl-2,2'-bipyridines have been identified as a promising candidate for such applications. Therefore, high resolution STM investigations at the solid-liquid interface have been conducted, to study the intermolecular interaction of the bipyridine moieties. The results provide inside in the self-organization behavior of 4,4¿-dimethyl-2,2¿-bipyridines and the conclusions might help to understand the molecular arrangement of this class of molecules and might serve, on the long term, as a key to optimize their interaction with respect to improved optoelectronic properties.
