Ortho O-Annulated AzaBenzannulated PeryleneDiimide and BisAzaCoroneneDiimide

The development of new n-type organic semiconductors is crucial to the development of organic electronics. The introduction of heteroatoms into electron-acceptor units enables their properties to be fine-tuned and new applications to emerge. In this study, we present the preparation of BisAzaCoroneneDiimide derivatives annulated by the insertion of oxygen in their ortho position. These compounds exhibit high planarity and their properties are sensitive to the extension of their π-system. Their performance in preliminary organic electronics studies is also reported.
