“…In 2021, Qiao, Pang and co-workers prepared a novel multi-stimuli responsive, multi-functional polymeric nanoparticle poly(2-(dimethylamino)ethyl methacrylate)-co -poly((4-vinylphenyl) ethene-1,1,2-triyl)tribenzene) with PDMAEMA as the organic carrier,grafted from SiO 2 surface as the inorganic carrier with asymmetrical encapsulation of Fe 3 O 4 nanoparticles (Fe 3 O 4 @SiO 2 @P(DMAEMA-co -TPEE)) (Figure 6A ). [128] The resulting composite nanoparticle possesses a yolk-shell (YS) morphology with the AIE-active TPEE block, allowing for real-time monitoring of any changes to environmental magnetic field, temperature and pH levels, with the added ability to detect CO 2 presence in aqueous solution. In addition to the commonly known pH/thermo-responsiveness of the PDMAEMA block, the incorporation of Fe 3 O 4 endows the polymer with superparamagnetism where higher PL intensity was observed for shorter distance to the source of magnetism.…”

Aggregation-Induced Emission (AIE) is a unique phenomenon whereby aggregation of molecules induces fluorescence emission as opposed to the more commonly known Aggregation-Caused Quenching (ACQ). AIE has the potential to be utilized in the large-scale production of AIE-active polymeric materials because of their wide range of practical applications such as stimuli-responsive sensors, biological imaging agents, and drug delivery systems. This is evident from the increasing number of publications over the years since AIE was first discovered. In addition, the ever-growing interest in this field has led many researchers around the world to develop new and creative methods in the design of monomers, initiators and crosslinkers, with the goal of broadening the scope and utility of AIE polymers. One of the most promising approaches to the design and synthesis of AIE polymers is the use of the Reversible-Deactivation Radical Polymerization (RDRP) techniques, which enabled the production of well-controlled AIE materials that are often difficult to achieve by other methods. In this review, a summary of some recent works that utilize RDRP for AIE polymer design and synthesis is presented, including (1) the design of AIE-related monomers, initiators/crosslinkers; the achievements in preparation of AIE polymers using (2) Reversible Addition-Fragmentation Chain Transfer (RAFT) technique; (3) Atom Transfer Radical Polymerization (ATRP) technique; (4) other techniques such as Cu(0)-RDRP technique and Nitroxide-Mediated Polymerization (NMP) technique; (5) the possible applications of these AIE polymers and finally (6) a summary/perspective and the future direction of AIE polymers.

“…For example, Hou and co-workers coassembled silica matrixes, superparamagnetic Fe 3 O 4 component, and TPE-functionalized polymers into a multistimulusresponsive fluorescent probe, as shown in Figure 3A. [63] Because the silica substrates can provide excellent colloidal stability and an easily modified platform, multiple components can be perfectly integrated into one system. TPE groups with AIE activity are bound to the polymer by covalent bonds and remain in a relatively "free" state within the polymer.…”

Luminogens with aggregation‐induced emission properties (AIEgens), as a novel and attractive fluorescent molecule, have been used in various fields, such as detection, imaging, and disease treatment, which can overcome the traditional aggregation‐caused quenching of organic fluorescent molecules. Nevertheless, AIEgens still have the problems of water solubility and fluorescence stability in practical applications. Aiming for improving the AIEgens’ performance and promoting the development of diverse applications of AIEgens, it is an available strategy to bind AIEgens to those inorganic materials with abundant variety, easy synthesis, and a unique rigid pore structure. The constructed inorganic‐based AIE materials not only inherit the unique luminescence characteristics of AIEgens, but also retain the biocompatibility and degradability of inorganic materials, endowing AIEgens with more attractive versatility. Herein, the up‐to‐date researches of several representative inorganic‐based AIE materials are introduced, with emphasis on their structure design, synthesis strategy, regulation of fluorescence properties of AIE, and their application in the biological field. Finally, the current situation, challenges, and future development potential of inorganic‐based AIE materials are discussed and prospected.

“…49,53−58 The embedding of AIEgens into polymer brushes has also offered control in optoelectronic properties and sensing applications. 59,60 In the present work, we synthesized concentrated to semidiluted polymer brushes via surface-initiated RCMP using an AIE monomer, i.e., 4-(1,2,2-triphenylvinyl)phenyl methacrylate (TPMA (Figure 2a)) for size recognition of external molecules. We prepared patterned polymer brushes with different graft densities to selectively capture external molecules of different sizes and detected the capture of the external molecules in the polymer brushes by the AIE intensities, enabling the size recognition of external molecules.…”

“…In 2001, Tang et al pioneered a class of aggregation-induced emission (AIE)-type luminogens (i.e., AIEgens) that exhibited enhanced emission in the aggregated states, which is a phenomenon opposite to ACQ. − Restriction of the molecular motions in the aggregated state suppresses thermal decay of the excited luminogens, resulting in enhanced photo-emission. AIEgens have also been incorporated in polymers, finding applications in microporous materials and biological applications. ,− The embedding of AIEgens into polymer brushes has also offered control in optoelectronic properties and sensing applications. , …”

Aggregation-induced emission (AIE)-driven fluorescent polymer brushes, i.e., poly(4-(1,2,2-triphenylvinyl)phenyl methacrylate) (PTPMA) brushes, were fabricated in a patterned manner with different graft-density domains. The obtained patterned brushes served as a molecular size analyzer; namely, the sizes of external molecules were recognized via the changes in the fluorescence intensities of the polymer brushes. Small-size external molecules were able to enter the polymer brush layers, inducing the fluorescent side groups in the brush chains to aggregate and enhancing the fluorescence intensity via AIE. On the other hand, large-size external molecules were unable to enter the polymer brush layer, resulting in no significant change in the fluorescence intensity. The size exclusion (molecular weight) threshold of external molecules depends on the graft density. As a demonstration, the present work distinguished external molecules with molecular weights of 300 and 1000 via the change in the fluorescence intensity of the brushes with different graft densities. The present patterning technique can tune the graft density in a wide range and hence may offer patterned brushes with a wide range of analyzable molecular sizes.
