Abstract
High Resolution Image Download MS PowerPoint Slide Bromo-functionalized B 1 -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 S 1 energies, with a number showing thermally activated delayed fluorescence and significant emission in the near-infrared region of the spectrum. These B 1 -PAHs represent a useful family of acceptors that can be readily synthesized and functionalized.
