Si-containing polycyclic aromatic hydrocarbons: synthesis and opto-electronic properties

Abstract

We report the straightforward synthesis of Si-containing PAHs (Polycyclic Aromatic Hydrocarbons). The impact of pi-extension and exocyclic modifications on both the optical and redox properties is investigated using a joint...

“…Finally, we also used this strategy to prepare a novel family of PAHs featuring two heteroatoms in the scaffold with various -extension and Si-substituents (57-59, Scheme 9). 51 All those systems remain planar according to X-ray crystallography and DFT. Contrary to what was observed on simpler silaphenalenes such 53, the double annulation strategy did not allow introducing functional groups on the alkyne.…”
