In the first section, the suitability of seven different perylene bisimide derivatives (1–7) with respect to nanotube dispersion and exfoliation in water has been investigated (Scheme 3.1) [1, 2]. The syntheses of these systems is described in the literature [2, 3]. As outlined by numerous studies [4–12], the inclusion of polycyclic aromatic units in nanotube dispersion additives enhances the interaction with the aromatic nanotube scaffold in comparison to classical detergents where the interaction is limited to van der Waals attraction.
