Chromophores that exhibit aggregation‐induced emission (i.e., aggregation‐induced emission luminogens [AIEgens]) emit intense fluorescence in their aggregated states, but show negligible emission as discrete molecular species in solution due to the changes in restriction and freedom of intramolecular motions. As solvent‐swollen quasi‐solids with both a compact phase and a free space, gels enable manipulation of intramolecular motions. Thus, AIE‐active gels have attracted significant interest owing to their various distinctive properties and promising application potential. Herein, a comprehensive overview of AIE‐active gels is provided. The fabrication strategies employed are detailed, and the applications of AIEgens are summarized. In addition, the gel functions arising from the AIE moieties are revealed, along with their structure–property relationships. Furthermore, the applications of AIE‐active gels in diverse areas are illustrated. Finally, ongoing challenges and potential means to address them are discussed, along with future perspectives on AIE‐active gels, with the overall aim of inspiring research on novel materials and ideas.

“…[21] In addition, with the aid of coordination of Hg 2 + and the redox reaction of glutathione (GSH), the fluorescence of PAA solution can be controlled in a reversible on-off manner, similar to the reported AIE-active polymers. [22][23][24] In brief, the non-conjugated AIE-polymers can be directly prepared from the accessible non-AIE monomers. The development of non-conjugated polymers provides more possibilities for their applications in the biological field such as imaging, detection, trace analysis and so on.…”

In this study, a series of polyamide‐amines (PAAs) were prepared by Michael addition reaction of piperazine derivatives with N, N‐bisacrylamidepiperazine (BAP). An obvious aggregation‐induced emission (AIE) effect was observed for PAAs with fluorescence emission at 425–525 nm and affected by the structure, excitation wavelength, pH value, temperature, PAAs concentration and precipitant (acetone). The piperazine rings and amides groups on PAAs backbone contribute to their AIE by the clusterization‐triggered emission (CTE) mechanism, in accordance with the red‐shift of time‐dependent density functional theory (DFT). The DFT results proved the influence of packing way on aggregation luminescence, clarified the cluster mechanism of luminescences, and the ultraviolet absorption spectrum of PAAs. Additionally, based on the coordination, Hg2+ ions effectively quenched the fluorescence intensity of PAAs and showed enhanced quenching effect with the increase of concentration of Hg2+ ions. And also, a reducing agent, glutathione, can restore the fluorescence of PAAs solution mixed with Hg2+ ions, by which realizes the reversible switching process between fluorescence on and fluorescence off.

“…The π-π interactions have been broadly investigated in the range of conjugated molecules as a universally existing intermolecular binding forces that occur among the inherent luminogens instead of effecting via postmodified functional groups, thus rendering it particularly effective in tuning fluorescence properties by straightly altering the packing modes. For many supramolecular architectures containing π-conjugated molecular entities, even though the assemblies are principally jointed by other intermolecular driving forces, π-π interactions are still indispensable within the structures, [56][57][58][59] which we will not discuss in detail in this section.…”

Aggregation‐induced emission systems involving supramolecular assembly

Aggregation‐induced emission (AIE), as an exciting photophysical phenomenon, has been regarded as one frontier research topic within both ranges of molecular luminescence and materials science over the last two decades. Since controllable molecular ensembles with particular morphologies and tunable functions can be elegantly constructed in the realm of supramolecular chemistry, the integration of supramolecular assembly and AIE systems can expectedly bring about luminescent materials with tunable emission and tailorable well‐ordered architectures. In this review, we will provide a summary of the creation and working mechanisms of AIE systems involving supramolecular systems that are driven by different supramolecular driving forces including hydrogen bonding, host−guest interactions, metal coordination, and π–π interactions. The morphological and photoluminescent features of these AIE‐active supramolecular assemblies will be elucidated, and the regulated fluorescence properties of the AIEgens induced by the assembling–disassembling processes will be discussed in detail.
