“…One of the aggregation-induced emission (AIE) materials have always been a hot topic in optical material research. − With the increasing maturity of AIE effect research, a large number of AIE effect molecular structures have been reported. At the same time, the application of the AIE effect is constantly being updated. − For example, Han et al used simple organic compounds to form supramolecular self-assembled hydrogels with AIE characteristics through intermolecular forces and showed reversible sol–gel transition under temperature or pH induction. By mixing with the fluorescent dye RhB, a light trapping gel system with high FRET (fluorescence resonance energy transfer) efficiency and fluorescence quantum yield was produced .…”

Amphiphilic rod−coil compounds have excellent photophysical properties and can be assembled into supramolecular nanostructures of different sizes in water or polar solvents. Herein, we synthesized the amphiphilic compounds 2N-DSA, 4N-DSA, and 6N-DSA with 9,10-distyrylanthracene (DSA) as the core and a naphthalene unit as the terminal group that connected DSA through a tetraethylene glycol chain. These compounds have excellent aggregation-induced emission (AIE) properties in aqueous solution and are assembled into worm-like fragments or different sizes of spherical assemblies, defending the volume ratio of the rod to coil segments. Notably, the donor−acceptor interaction between DSA and electron-deficient compounds 2,4,6-trinitrophenol (TNP), 2,4,5,7-tetranitrofluorenone (TNF), and tetraethylene glycol dinitrobenzoate (TGDNB) forms a charge transfer complex, which can be used as a nanoreactor to improve the yield of the Suzuki coupling reaction about 8−10 times. The experimental results reveal that the synergy effect of the donor−acceptor, intermolecular π−π stacking, and hydrophobic−hydrophilic interactions significantly influences the morphology of aggregates and the efficiency of the nanoreactor.

“…Recently, many MCRs have been widely used in the development of new functional polymers. These MCRs include the Passerini [1,2], Ugi [3,4], Biginelli [5][6][7], Kabachnik-Fields [8,9], Hantzsch [10,11], and Mannich reactions [12,13] as well as thiolactone-based [14] and metal-catalyzed multicomponent reactions [15]. The functional polymers prepared by means of these MCRs have been further applied in the fields of environmental science [16,17], material science [18,19], and biomedicine [20].…”

Recently, multicomponent reactions (MCRs) have attracted much attention in polymer synthesis. As one of the most well-known MCRs, the Kabachnik–Fields (KF) reaction has been widely used in the development of new functional polymers. The KF reaction can efficiently introduce functional groups into polymer structures; thus, polymers prepared via the KF reaction have unique α-aminophosphonates and show important bioactivity, metal chelating abilities, and flame-retardant properties. In this mini-review, we mainly summarize the latest advances in the KF reaction to synthesize functional polymers for the preparation of heavy metal adsorbents, multifunctional hydrogels, flame retardants, and bioimaging probes. We also discuss some emerging applications of functional polymers prepared by means of the KF reaction. Finally, we put forward our perspectives on the further development of the KF reaction in polymer chemistry.
