In the last few years, electron-deficient materials have been actively researched for application in organic light-emitting diode (OLED) as dopant and electron-transporting materials. The boron-containing materials are interesting as they give good emissive properties in solid state with an electron-accepting character. Recently, many boron-containing materials are used as emissive materials for thermally activated delayed fluorescence (TADF) OLED applications. In this review, boron acceptor-based push-pull small molecules used for application in blue TADF OLEDs are reviewed, covering their different types of acceptor, molecular design, structure-property relation, material properties, and device properties. Also, the importance of boron acceptors to address the key issue of blue TADF OLEDs is discussed.
在过去几年中，缺电子材料作为掺杂剂和电子传输材料在有机发光二极管（OLED）中的应用受到了积极研究。含硼材料因其在固态下具有良好的发射特性和电子接受特性而备受关注。最近，许多含硼材料被用作热激活延迟荧光（TADF）OLED应用的发光材料。在本综述中，对用于蓝色TADF OLED的基于硼受体的推拉小分子进行了综述，涵盖了它们不同类型的受体、分子设计、结构-性能关系、材料性能和器件性能。此外，还讨论了硼受体对于解决蓝色TADF OLED关键问题的重要性。
