热激活延迟荧光（TADF）材料作为发光体和主体的设计是一个爆炸性的研究领域。在电致发光（EL）器件中，用廉价的有机化合物取代磷光金属络合物，表现出相当的性能指标，这是一种范式转变，因为这些新材料提供了开发低成本照明和显示器的可能性。在这里，TADF材料的全面审查，重点是连接它们的光电行为与有机发光二极管（OLED）和相关的EL器件的性能。TADF发射器在特定的颜色范围内进行交叉比较，重点是蓝色，绿黄色，橙红色和白色OLED。有机小分子，树枝状聚合物，聚合物和激基复合物发射体都在这篇评论中进行了讨论，因为它们作为主体材料的用途。TADF材料的结构和它们的光电性能之间的相关性。TADF材料的成功迎来了下一代OLED。
The design of thermally activated delayed fluorescence (TADF) materials both as emitters and as hosts is an exploding area of research. The replacement of phosphorescent metal complexes with inexpensive organic compounds in electroluminescent (EL) devices that demonstrate comparable performance metrics is paradigm shifting, as these new materials offer the possibility of developing low-cost lighting and displays. Here, a comprehensive review of TADF materials is presented, with a focus on linking their optoelectronic behavior with the performance of the organic light-emitting diode (OLED) and related EL devices. TADF emitters are cross-compared within specific color ranges, with a focus on blue, green-yellow, orange-red, and white OLEDs. Organic small-molecule, dendrimer, polymer, and exciplex emitters are all discussed within this review, as is their use as host materials. Correlations are provided between the structure of the TADF materials and their optoelectronic properties. The success of TADF materials has ushered in the next generation of OLEDs.
