Abstract

Bromo-functionalized B-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 energies, with a number showing thermally activated delayed fluorescence and significant emission in the near-infrared region of the spectrum. These B-PAHs represent a useful family of acceptors that can be readily synthesized and functionalized.

摘要

合成了最低未占分子轨道（LUMO）小于-3.0电子伏特的溴官能化硼多环芳烃（PAH），并将其用于交叉偶联反应以形成供体-受体材料。这些材料具有一系列的单重态能量，其中一些显示出热激活延迟荧光，并在光谱的近红外区域有显著发射。这些硼多环芳烃代表了一类有用的受体家族，它们易于合成且可官能化。
