What is it about?
AIE research in recent decades has rapidly propagated into various fields, encompassing physics, chemistry, materials science, optics and electronics, engineering science, and biomedical sciences. The diversity of the AIE-derived composite materials is immense, and there are numerous opportunities to engineer innovative material systems. Rational design of bespoke AIEgen materials coupled with electrospinning methodologies could revolutionize the way future materials are being designed and engineered toward specific functions in various field.

Why is it important?
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
