Large polycyclic aromatic hydrocarbons (PAHs) are among the most important research targets in organic materials chemistry. Characterized by precisely defined structures and often functionalizable peripheries, they act as discrete graphene-like models (nanographenes, graphene nanoribbons, carbon nanotubes). They can also be designed to contain heteroatoms or non-benzoid rings, which greatly alters their properties. The prospective use of these molecules in organic electronics requires precise control over their π-conjugation. The synthesis of extended PAH systems can, in principle, be simplified by employing a modular approach, in which suitably designed building blocks are covalently assembled into larger fused structures. In my talk I will show various examples of nanographenoid molecules designed in our research group and describe their properties, including fluorescence, near-infrared absorptions, solvatochromism or host-guest interactions.
