Abstract
Bromo-functionalized B1-polycyclic aromatic hydrocarbons (PAHs) with LUMOs of less than −3.0 eV were synthesized and used in cross-couplings to form donor–acceptor materials. These materials spanned a range of S1 energies, with a number showing thermally activated delayed fluorescence and significant emission in the near-infrared region of the spectrum. These B1-PAHs represent a useful family of acceptors that can be readily synthesized and functionalized.
