Brominated B(1)-Polycyclic Aromatic Hydrocarbons for the Synthesis of Deep-Red to Near-Infrared Delayed Fluorescence Emitters

[Image: see text] 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 fluor...

Sumario:[Image: see text] 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.
