The incorporation of heteroatoms directly into the sp2-carbon skeleton of polycyclic aromatic hydrocarbons (PAHs) provides a powerful tool - next to variation of their size and periphery and/or lateral decoration with various substituents - to manipulate the optoelectronic properties and supramolecular behavior. Nitrogen is particularly appealing in this context as it can readily adopt a planar sp2-hybridized geometry to enable for efficient electronic communication with the surrounding system. The resulting nitrogen-containing PAHs are highly attractive objects for experimental and theoretical studies as defined molecular fragments of heteroatom-doped carbon allotropes on one hand and as functional materials for diverse applications on the other. We have recently identified various relatively simple triarylamines as versatile building blocks for the construction of unprecedented nitrogen-containing PAHs with appealing electronic and materials characteristics.[3-5] In this talk, our respective efforts involving synthesis in solution and on surfaces will be presented and fundamental characteristics of the resulting compounds discussed.
