Abstract

The self-assembly of two emeraldine base tetra(aniline) derivatives is investigated using scanning tunneling microscopy. A combination of the scanning tunneling microscopy data and calculations reveals the presence of predicted cis/trans isomerism in this oxidation state. This isomerism is shown to hinder self-assembly into ordered structures, and provides indications as to why the properties of these materials, and their parent polymer, polyaniline, remain unfulfilled.

19. The cis isomer shown in Figure 2b shows an even further reduced angle (≈30° length ≈2.3 nm) with a strong likelihood that these angles will vary with the local environment of each molecule.
