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.
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.
