“…Nowadays, the development of reversible covalent bond has empowered polymer chemists with the ability to prepare architecture‐transformable polymers . The similar idea could be applied on the POSS‐hybrid polymers, for instance, Singha et al have reported that a furan containing polyurethane (FPU)‐POSS maleimide isobutyl(POSS‐M) (FPU‐POSS‐M hybrid) 57 was synthesized by introducing a Diels–Alder (DA) linkage based on furan‐maleimide (Fur‐Mal) reaction, which presented self‐healable behavior and ultrahydrophobicity .…”

Polyhedral oligomeric silsesquioxane (POSS)‐hybrid polymers have been successfully employed as functional inorganic–organic hybrid materials for various applications due to their well‐determined structures. The past 6 years has witnessed growing interest in the rational design and synthetic approaches for POSS‐hybrid polymers, driven by the adoption of controlled living radial polymerization and click chemistry. This review addresses developments in the precise manipulation of POSS building blocks via atom transfer radical polymerization, reversible addition–fragmentation chain transfer, and click chemistry. Not only are the structures of POSS‐hybrid polymers tunable in terms of chemical composition, molecular weight, and polydispersity, but they are also controllable in sequential and hierarchical chain topology. Finally, some representative cutting‐edge applications of POSS‐hybrid polymers, including biomedical and energy‐related materials, fabrication of nanostructures, and functional surface coating materials, are highlighted.

“…In case of polymers, not only the size but also the architecture (shape) plays a pivotal role on the polymer properties like aggregation, flowability, strength, etc . With a change in their molecular architecture, their physical and chemical properties also change . Recently, Sumerlin et al successfully demonstrated “macromolecular metamorphosis” (change in macromolecular architecture) by using different Diels–Alder reactions .…”

In this work, a rational strategy of competitive host–guest complexation between dioxynaphthalene (Naph) and tetrathiafulvalene (TTF) subunits as guests and cyclophane cyclobis(paraquat‐p‐phenylene) (CBPQT4+) module as host is exploited to modify the macromolecular architecture, so‐called supramolecular metamorphosis, in aqueous media. The architectures of the polymers can be reversibly transformed from a linear diblock copolymer AB to a linear AC block copolymer or from a linear block copolymer to a comb copolymer by redox switching. Interestingly, as TTF‐ and Naph‐based complexes feature different characteristic colors, it offers a great opportunity to directly observe nanoscaled macromolecular metamorphosis of materials with the naked eye.

“…Stimuli-responsive materials can undergo relatively large and abrupt physical or chemical changes in response to small external stimuli [1,2]. In the last few decades, stimuli-responsive functional gels, responsive to light, temperature, pH, ionic strength, force, and redox reactions, among others, have attracted significant attention in sensing, drug delivery, and biotechnology [3][4][5][6][7][8][9][10][11]. Among these functionalities, redox-responsive polymer gels play an important role for application in physiological environments, where the redox process is constantly and widely present [12][13][14].…”

Novel AIEgen-Functionalized Diselenide-Crosslinked Polymer Gels as Fluorescent Probes and Drug Release Carriers

Stimuli-responsive functional gels have shown significant potential for application in biosensing and drug release systems. In this study, aggregation-induced emission luminogen (AIEgen)-functionalized, diselenide-crosslinked polymer gels were synthesized via free radical copolymerization. A series of polymer gels with different crosslink densities or tetraphenylethylene (TPE) contents were synthesized. The diselenide crosslinker in the gels could be fragmented in the presence of H2O2 or dithiothreitol (DTT) due to its redox-responsive property. Thus, the TPE-containing polymer chains were released into the aqueous solution. As a result, the aqueous solution exhibited enhanced fluorescence emission due to the strong hydrophobicity of TPE. The degradation of polymer gels and fluorescence enhancement in an aqueous solution under different H2O2 or DTT concentrations were studied. Furthermore, the polymer gels could be used as drug carriers, suggesting a visual drug release process under the action of external redox agents. The AIEgen-functionalized, diselenide-crosslinked polymer gels hold great potential in the biomedical area for biosensing and controlled drug delivery.
