The Marriage of Aggregation-Induced Emission with Polymer Science.

Aggregation-induced emission (AIE) is a novel photophysical phenomenon coined in 2001 by our group and describes the enhanced light emission of some luminogens in the aggregate or solid state. The combination of AIE research and polymer science is a smart approach to produce functional luminescent materials with mechanical strength and excellent processability for real-world applications. In this feature article, recent progress in AIE polymeric systems, including chemical synthesis and physical blending strategies, is summarized. Through chemical synthesis, various AIE-active polymers, such as covalently bonded polymers, supramolecular polymers, and nonconjugated luminescent polymers, can be obtained. Serving as environmentally sensitive probes, AIE luminogens can also be physically doped into polymers to generate interesting systems. Finally, outlooks and perspectives on the future direction of AIE polymeric systems are discussed.
