Polycyclic aromatic hydrocarbons (PAHs) are fragments of graphene prepared in various sizes and shapes to adapt their optoelectronic properties. This structure-property relationship allows material chemists to design conjugated materials with specific properties, tailored for organic electronics devices. Introducing heteroatoms, such as nitrogen or sulfur, into their core is a powerful strategy to tune their frontier orbitals energy, as well as their optical, semiconducting and self-assembly properties. The inclusion of oxygen atoms in the skeleton of PAHs lead to applications ranging from chiroptics 7 and spintronics 8 to organic electronics 9 and photocatalysis. Bonifazi and co-workers 11 have extensively studied the synthesis and properties of oxygen-doped PAHs resulting in a collection of functional conjugated systems for electrochromic displays, 12 photocatalysis, charge transport, and nonlinear optics. These oxygendoped PAHs are prepared through a copper-catalysed oxidative C-H activation of hydroxy-decorated PAHs precursors. The vast majority of these materials are electron-rich, p-type materials. The exploration of electron poor, n-type, O-decorated PAHs lags behind and few examples have been reported so far. Notable examples are coming again from Bonifazi and co-workers 17 who reported oxygencontaining rylene diimide and monoimide derivatives showing low LUMO energies and a wide visiblelight absorption. Fujimoto and Izawa 18 described a distorted bay O-annulated perylene diimide (PDI) derivative bearing seven-membered rings which has been exploited as a non-fullerene acceptor (NFA) in organic solar cells (OSCs). Recently, Zeng and co-workers reported the synthesis of an O-doped rylene diimide derivative showing efficient near-infrared fluorescence.
