Author(s): Stephanie Hoeppener, Veronica N. Marin, Ulrich S. Schubert.

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.
