The development of a one-step borylation of 1,3-diaryloxybenzenes, yielding novel boron-containing polycyclic aromatic compounds, is reported. The resulting boron-containing compounds possess high singlet-triplet excitation energies as a result of localized frontier molecular orbitals induced by boron and oxygen. Using these compounds as a host material, we successfully prepared phosphorescent organic light-emitting diodes exhibiting high efficiency and adequate lifetimes. Moreover, using the present one-step borylation, we succeeded in the synthesis of an efficient, thermally activated delayed fluorescence emitter and boron-fused benzo[6]helicene.
本文报道了一种一步硼化 1,3-二芳氧基苯的方法，生成了新型含硼多环芳烃化合物。由于硼和氧诱导的局域前线分子轨道，得到的含硼化合物具有高的单重态-三重态激发能。将这些化合物作为主体材料，我们成功制备了磷光有机发光二极管，其表现出高效率和适当的寿命。此外，使用本研究中的一步硼化反应，我们成功合成了一种高效的热激活延迟荧光发射体和硼稠合苯并[6]并[1,2-b]噻吩。
