摘要：
Bromo-functionalizedB(1)-polycyclic aromatic hydrocarbons(PAHs) with LUMOs of less than -3.0 eV were synthesized andused in cross-couplings to form donor-acceptor materials. Thesematerials spanned a range of S-1 energies, with a numbershowing thermally activated delayed fluorescence and significant emission in the near-infrared region of the spectrum. These B-1-PAHsrepresent a useful family of acceptors that can be readily synthesizedand functionalized.
