Abstract

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.

Design strategies and applications (light-harvesting, fluorescent probe and theranostics) of AIEgen-based excitation energy systems are discussed in this review.

利用激发能转移调制聚集诱导发射:设计与应用
激发能转移(EET)作为一种基本的光物理过程,在开发具有可调光物理性质的功能材料方面得到了很好的探索。与传统的荧光基团相比,聚集诱导发射发光基团(AIEgens)具有聚集态荧光明亮、吸收和发射光谱宽、Stokes位移大、耐光漂白等优异的光物理性质,在构建EET系统中具有独特的优势,特别是作为能量供体。此外,AIEgens的光物理性质可以通过能量转移来调节,以提高发光性能。因此,人们构建了各种基于AIEgens的EET系统,并探索了它们在不同领域的应用。在这篇综述中,我们总结了基于人工智能的能量传递系统在光收集、荧光探针和治疗系统的设计策略方面的最新进展,重点介绍了实现理想性能的设计策略。简要概述了ae - eet系统的局限性、挑战和未来机遇。本文综述了基于aiegen的激发能系统的设计策略和应用(光收集、荧光探针和治疗学)。

期刊介绍: Topics in Current Chemistry is a journal that presents critical reviews of present and future trends in modern chemical research. It covers all areas of chemical science, including interactions with related disciplines like biology, medicine, physics, and materials science. The articles in this journal are organized into thematic collections, offering a comprehensive perspective on emerging research to non-specialist readers in academia or industry. Each review article focuses on one aspect of the topic and provides a critical survey, placing it in the context of the collection. Selected examples highlight significant developments from the past 5 to 10 years. Instead of providing an exhaustive summary or extensive data, the articles concentrate on methodological thinking. This approach allows non-specialist readers to understand the information fully and presents the potential prospects for future developments.
