Brominated B₁-Polycyclic Aromatic Hydrocarbons for the Synthesis of Deep-Red to Near-Infrared Delayed Fluorescence Emitters.

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.
