An anthracene unit was successfully fused to the zigzag edge of a boron dipyrromethene (BODIPY) core by an FeCl3-mediated
oxidative cyclodehydrogenation reaction. Meanwhile, a dimer was also
formed by both intramolecular cyclization and intermolecular coupling.
The anthracene-fused BODIPY monomer 7a and dimer 7b showed small energy gaps (∼1.4 eV) and near-infrared absorption/emission. Moreover, they exhibited high photostability.
