Excitation energy transfer (EET) as a fundamental photophysical process is well-explored for developing functional materials with tunable photophysical properties. Compared to traditional fluorophores, aggregation-induced emission luminogens (AIEgens) exhibit unique advantages for building EET systems, especially serving as energy donors, due to their outstanding photophysical properties such as bright fluorescence in aggregation state, broad absorption and emission spectra, large Stokes shift, and high photobleaching resistance. In addition, the photophysical properties of AIEgens can be modulated by energy transfer for improved luminescence performance. Therefore, a variety of EET systems based on AIEgens have been constructed and their applications in different areas have been explored. In this review, we summarize recent progress in the design strategy of AIE-based energy transfer systems for light-harvesting, fluorescent probes and theranostic systems, with an emphasis on design strategies to achieve desirable properties. The limitations, challenges and future opportunities of AIE–EET systems are briefly outlined.

激发能传递对聚集诱导排放的调节：设计与应用
激发能转移（EET）作为一种基本的光物理过程，已被广泛用于开发具有可调光物理特性的功能材料。与传统的荧光团相比，聚集诱导的发射光致发光剂（AIEgens）具有独特的光物理特性，例如聚集态的明亮荧光，宽广的吸收和发射光谱，大的斯托克斯位移，因此在建筑EET系统（尤其是作为能量供体）方面显示出独特的优势。 ，并且具有高的耐光漂白性。另外，可以通过能量转移来调节AIEgen的光物理性质，以改善发光性能。因此，已经构建了多种基于AIEgens的EET系统，并探索了它们在不同领域中的应用。在这篇评论中，我们总结了基于AIE的能量收集系统（用于光收集，荧光探针和诊断学系统）的设计策略的最新进展，重点放在了实现所需性能的设计策略上。简要概述了AIE-EET系统的局限性，挑战和未来机会。
