“…Thus, greater efforts are needed urgently. Compared with chemotherapy for infectious diseases, treatment with AIEgenbased modalities has shown prominent outcomes in terms of protection 235,236 and therapeutics. 237,238 The most effective method to cure an infectious disease is to kill the pathogen completely.…”

“…[ 97 , 98 ] The recent reviews have covered the various excited state phenomena associated with AIEgens, such as TICT (twisted intramolecular charge transfer), PET (photo‐induced electron transfer), RIR (restriction of intramolecular motion), and ISC (intersystem crossing) in fiber, which have been used for smart sensing in fields such as biomedical, energy conversion, and electronics. [ 98 , 99 ] Existing reviews concentrate on how AIE properties are enhanced in the fiber; however, the relationship between fiber morphology and structural interaction with AIE aggregates is not thoroughly explored. Until now, the attention was given to the incorporation of AIE materials in fiber and the plausible AIE mechanisms.…”

“…Until now, the attention was given to the incorporation of AIE materials in fiber and the plausible AIE mechanisms. [ 97 , 98 , 99 ] Encouragingly, the results to date suggest that electrospun nanofibers and porous films/membranes incorporating AIEgens hold a lot of promise, since they offer enhanced photostability, photothermal properties, photoefficiency, and sensitivity. In this review, we have adopted a different approach and concentrate our discussions on the structure−processing−property relationships of AIE‐active electrospun fibers.…”

This review addresses the latest advancements in the integration of aggregation-induced emission (AIE) materials with polymer electrospinning, to accomplish fine-scale electrospun fibers with tunable photophysical and photochemical properties. Micro-and nanoscale fibers augmented with AIE dyes (termed AIEgens) are bespoke composite systems that can overcome the limitation posed by aggregation-caused quenching, a critical deficiency of conventional luminescent materials. This review comprises three parts. First, the reader is exposed to the basic concepts of AIE and the fundamental mechanisms underpinning the restriction of intermolecular motions. This is followed by an introduction to electrospinning techniques pertinent to AIE-based fibers, and the core parameters for controlling fiber architecture and resultant properties. Second, exemplars are drawn from latest research to demonstrate how electrospun nanofibers and porous films incorporating modified AIEgens (especially tetraphenylethylene and triphenylamine derivatives) can yield enhanced photostability, photothermal properties, photoefficiency (quantum yield), and improved device sensitivity. Advanced applications are drawn from several promising sectors, encompassing optoelectronics, drug delivery and biology, chemosensors and mechanochromic sensors, and innovative photothermal devices, among others. Finally, the outstanding challenges together with potential opportunities in the nascent field of electrospun AIE-active fibers are presented, for stimulating frontier research and explorations in this exciting field.

Aggregation‐induced emission luminogens (AIEgens) have recently been developed at a tremendous pace in the area of organic luminescent materials by virtue of their superior properties. However, the practical applications of AIEgens still face the challenge of transforming AIEgens from molecules into materials. Till now, many AIEgens have been integrated into fiber, endowing the fiber with prominent fluorescence and/or photosensitizing capacities. AIEgens and fiber complement each other for making progress in flexible smart materials, in which the utilization of AIEgens creates new application possibilities for fiber, and the fiber provides an excellent carrier for AIEgens towards realizing the conversion from molecule to materials and an ideal platform to research the aggregate state of AIEgens in mesoscale and macroscale. This review begins with a brief summary of the recent advances related to some typical AIEgens with various functions and the technology for the fabrication of AIEgen‐functionalized fiber. The most representative applications are then highlighted by focusing on energy conversion, personal protective equipment, biomedical, sensor, and fluorescence‐related fields. Finally, the challenges, opportunities, and tendencies in future development are discussed in detail. This review hopes to inspire innovation in AIEgens and fiber from the view of mesoscale and macroscale.
