Si-doped Polycyclic Aromatic Hydrocarbons: Synthesis and Opto-electronic Properties

Abstract

We report the straightforward synthesis of Si-containing PAHs. The impact of pi-extension and exocyclic modifications on both the optical and redox properties is investigated using a joint experimental/theoretical approach. By taking advantage of the solid-state luminescence of these derivatives, electroluminescent devices are prepared. Such preliminary optoelectronic results highlight that these heteroatom-containing PAHs are promising building blocks for organic electronics.
