The development of luminescent materials via mechanochemistry embodies a compelling yet intricate frontier within science. Herein, we delineate methodology for the synthesis brightly polymers, achieved by mechanochemical coupling aggregation-induced emission (AIE) prefluorophores with generic polymers. An array AIE moieties tethered to 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical are synthesized as prefluorophores, which initially exhibit weak fluorescence due intramolecular quenching. Remarkably, mechanical these macromolecular radicals, engendered through ball milling leads substantial augmentation resultant We meticulously evaluate tunable AIE-modified encompassing an extensive spectrum from visible near-infrared region. This study elucidates potential such in stimuli-responsive systems focus on information storage and encryption displays. By circumventing complexity inherent conventional this approach contributes paradigm field AIE-based polymers implications advanced technological applications.

Nature has inspired scientists to fabricate adhesive materials for applications in many burgeoning areas. However, it is still a significant challenge develop small-molecule adhesives with high-strength, low-temperature and recyclable properties, although these merits are of great interest various aspects. Herein, we report series strong based on low-molecular-weight molecular solids driven by the terminal modification ionic liquids (ILs) subsequent supramolecular self-assembly. The emergence high strength liquid-to-solid transitions aggregates relies modifying IL melting point motif enriching types noncovalent interactions original ILs. Using this strategy, demonstrate that our IL-based can efficiently obtain adhesion (up 8.95 MPa). Importantly, elucidate mechanism underlying reversible enabled monomer-to-polymer transitions. These fundamental findings provide guidance design high-performance materials.

A Universal Strategy for Constructing Hydrogel Assemblies Enabled by PAA Hydrogel Adhesive

Small, Год журнала: 2024, Номер 20(43)

Опубликована: Июнь 22, 2024

Abstract Hydrogel is a significant type of building block for constructing macroscopic assemblies, the construction which usually entails incorporation supramolecular groups. However, group recognition specific and only suitable assembling two particular modified hydrogels, but not versatile strategy. Herein, universal strategy without modification process proposed using polyacrylic acid (PAA) hydrogel as adhesive layer to assemble different kinds hydrogels. Furthermore, assemblies with various shapes multi‐stimuli responsiveness are constructed by stimuli‐responsive hydrogels PAA hydrogel. Therefore, able complete bending motions upon applying corresponding stimuli. This provides approach also shows potential developing soft robots functions.

Malleable, Ultrastrong Antibacterial Thermosets Enabled by Guanidine Urea Structure

Advanced Science, Год журнала: 2024, Номер 11(30)

Опубликована: Июнь 13, 2024

Abstract Dynamic covalent polymers (DCPs) that strike a balance between high performance and rapid reconfiguration have been challenging task. For this purpose, solution is proposed in the form of new dynamic supramolecular motif—guanidine urea structure (GUAs). GUAs contain complex diverse chemical structures as well unique bonding characteristics, allowing guanidine to demonstrate advanced physical properties. Noncovalent interaction aggregates (NIAs) confirmed GUA‐DCPs through multistage H‐bonding π‐π stacking, resulting an extremely Young's modulus 14 GPa, suggesting remarkable mechanical strength. Additionally, guanamine linkages GUAs, type bond, provide resins with excellent malleability reprocessability. Guanamine metathesis validated using small molecule model compounds, temperature dependent infrared rheological behavior following dissociative exchange mechanism. Moreover, inherent photodynamic antibacterial properties are extensively verified by experiments. Even after undergoing three reprocessing cycles, rate remains above 99% 24 h, highlighting their long‐lasting effectiveness. nature, tuneable composition, combination make them promising candidates for various technological advancements.

Exclusive and Switchable Superoxide Radical Generation by O₂‐Capture‐Based Electron Transfer and Supramolecular Assembly

Small, Год журнала: 2024, Номер 20(24)

Опубликована: Янв. 4, 2024

Abstract Type‐I photosensitizers (PSs) can generate free radical anions with a broad diffusion range and powerful damage effect, rendering them highly desirable in various areas. However, it still remains recognized challenge to develop pure PSs due the inefficiency producing oxygen through collision of nearby substrates. In addition, regulating generation is also great importance toward control photosensitizer (PS) activities on demand. Herein, piperazine‐based cationic PS (PPE‐DPI) that exhibits efficient intersystem crossing subsequently captures molecules binding O 2 lone pair nitrogen piperazine reported. The close spatial vicinity between PPE‐DPI strongly promotes electron transfer reaction, ensuring exclusive superoxide (O •− ) via process. Particularly, pyridine groups able associate cucurbit[7]uril (CB[7]) host‐guest interactions. Thus, supramolecular assembly disassembly are easily utilized realize switchable generation. This successfully employed photodynamic antibacterial control.
