Since the seminal report by Adachi and co-workers in 2012, there has been a veritable explosion of interest in the design of thermally activated delayed fluorescence (TADF) compounds, particularly as emitters for organic light-emitting diodes (OLEDs). With rapid advancements and innovation in materials design, the efficiencies of TADF OLEDs for each of the primary color points as well as for white devices now rival those of state-of-the-art phosphorescent emitters. Beyond electroluminescent devices, TADF compounds have also found increasing utility and applications in numerous related fields, from photocatalysis, to sensing, to imaging and beyond. Following from our previous review in 2017 ( Adv. Mater. 2017, 1605444), we here comprehensively document subsequent advances made in TADF materials design and their uses from 2017–2022. Correlations highlighted between structure and properties as well as detailed comparisons and analyses should assist future TADF materials development. The necessarily broadened breadth and scope of this review attests to the bustling activity in this field. We note that the rapidly expanding and accelerating research activity in TADF material development is indicative of a field that has reached adolescence, with an exciting maturity still yet to come.

热激活延迟荧光材料的黄金时代：设计与开发


自 2012 年 Adachi 及其同事的开创性报告以来，人们对热激活延迟荧光 （TADF） 化合物的设计产生了真正的爆炸式增长，尤其是作为有机发光二极管 （OLED） 的发射器。随着材料设计的快速进步和创新，TADF OLED 的每个原色点以及白色器件的效率现在可以与最先进的磷光发射器相媲美。除了电致发光器件，TADF 化合物还在许多相关领域中获得了越来越多的用途和应用，从光催化到传感，再到成像等等。根据我们 2017 年的上一次审查 （ Adv. Mater.2017 年 1605444 月），我们在这里全面记录了 2017 年至 2022 年 TADF 材料设计及其用途的后续进展。强调结构和性能之间的相关性以及详细的比较和分析将有助于未来的 TADF 材料开发。这篇评论必然扩大了广度和范围，证明了这一领域的熙熙攘攘。我们注意到，TADF 材料开发中迅速扩大和加速的研究活动表明该领域已进入青春期，令人兴奋的成熟尚未到来。
