三重态收获对于高效光电子器件、时间分辨生物成像、传感和防伪器件是重要的。从供体（D）到受体（A）的福斯特共振能量转移（FRET）对于在各种激发后有效地收获三重态激子是重要的。然而，除了D的发射和A的吸收之间的光谱重叠之外，还没有报道通过反向系间穿越从单重态的FRET（FRETS-S）和从三重态的FRET（FRET-S）的关键因素的一般解释。这篇专题文章概述了涉及三重态的FRET。在讨论了考虑自旋禁戒因素的D态对FRET辐射产额的贡献后，介绍了FRETS-S、FRETS-S和FRETT-S的双重FRETT-S以及选择性FRETT-S等多种涉及三重态的方案。代表性的例子，包括化学结构和FRET三重收获，突出使用新兴的应用在光电子学和余辉成像。最后，使用FRET涉及三重态的高效率的光电器件和时间分辨生物成像的最新发展进行了讨论。这篇文章提供了关键的信息，用于控制国家的最先进的性能使用FRET涉及的三重态。
Triplet harvesting is important for high-efficiency optoelectronics devices, time-resolved bioimaging, sensing, and anti-counterfeiting devices. Förster resonance energy transfer (FRET) from the donor (D) to the acceptor (A) is important to efficiently harvest the triplet excitons after a variety of excitations. However, general explanations of the key factors of FRET from the singlet state (FRETS-S) via reverse intersystem crossing and FRET from the triplet state (FRETT-S) have not been reported beyond spectral overlap between emission of the D and absorption of the A. This feature article gives an overview of FRET involving the triplet state. After discussing the contribution of the radiation yield from the state of the D considering spin-forbidden factors of FRET, a variety of schemes involving triplet states, such as FRETS-Svia reverse intersystem crossing from the triplet state, dual FRETS-S and FRETT-S, and selective FRETT-S, are introduced. Representative examples, including the chemical structure and FRET for triplet harvesting, are highlighted using emerging applications in optoelectronics and afterglow imaging. Finally, recent developments of using FRET involving triplet states for high-efficiency optoelectronic devices and time-resolved bioimaging are discussed. This article provides crucial information for controlling state-of-the-art properties using FRET involving the triplet state.
