摘要

基于无金属热激活延迟荧光(TADF)材料的第三代有机发光二极管(OLED)具有近 100% 的激子利用效率,可以解决第一代荧光发光体的低效率问题和第二代有机金属磷光发光体的高成本问题,因此在过去十年中引发了极大的关注。构建高效稳定的 TADF-OLED 需要利用具有窄单线-三线能隙(ΔEST)、高光致发光量子产率(PLQY)和短 TADF 寿命的 TADF 材料。高效的反向系统间交叉(RISC)过程需要较小的ΔEST,而这可以通过有效分离最高占位分子轨道(HOMO)和最低未占位分子轨道(LUMO)来实现。TADF 发射器通常被设计为分子内电荷转移(ICT)分子,具有高度扭曲的供体-受体(D-A)分子结构。人们探索了多种电子供体和受体的组合。在本综述中,我们将重点介绍结合了强电子供体吩嗪分子的有机 TADF 分子的最新进展及其在有机发光二极管中作为发光层(EML)的应用。

Recent Progress in Phenoxazine-Based Thermally Activated Delayed Fluorescent Compounds and Their Full-Color Organic Light-Emitting Diodes

Third-generation organic light-emitting diodes (OLEDs) based on metal-free thermally activated delayed fluorescent (TADF) materials have sparked tremendous interest in the last decade due to their nearly 100% exciton utilization efficiency, which can address the low-efficiency issue of the first-generation fluorescent emitters and the high-cost issue of the second-generation organometallic phosphorescent emitters. Construction of efficient and stable TADF-OLEDs requires utilizing TADF materials with a narrow singlet–triplet energy gap (ΔEST), high photoluminescence quantum yield (PLQY) and short TADF lifetime. A small ΔEST is necessary for an efficient reverse intersystem crossing (RISC) process, which can be achieved through the effective spatial separation of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). TADF emitters have been generally designed as intramolecular charge transfer (ICT) molecules with highly twisted donor–acceptor (D–A) molecular architectures. A wide variety of combinations of electron donors and acceptors have been explored. In this review, we shall focus on recent progress in organic TADF molecules incorporating strong electron-donor phenoxazine moiety and their application as emitting layer (EML) in OLEDs.
