Abstract Phosphorescent supramolecular hydrogels are currently a prevalent topic for their great promise in various photonic applications. Herein, an efficient near‐infrared (NIR) phosphorescence hydrogel is reported via the hierarchical assembly strategy aqueous solution, which fabricated from amphiphilic bromonaphthalimide pyridinium derivative (G), exfoliated Laponite (LP) nanosheets, and polymeric polyacrylamide (PAAm). Initially, G spontaneously self‐aggregates into spherical nanoparticles covered with positively charged units emits single fluorescence at 410 nm. Driven by electrostatic interactions negatively subsequently function as cross‐linked binders coassemble LP engendered red room‐temperature (RTP) up to 620 Benefiting hydrogen‐bonding interactions‐mediated physical cross‐linkage, further introduction of PAAm not only significantly elevates mechanical strength showing fast self‐healing capability, but also increases lifetime 2.49 4.20 ms, especially generating even higher temperature ( τ 363 K = 2.46 ms). Additionally, RTP energy transfer occurs after doping small amount organic dye heptamethine cyanine (IR780) acceptor hydrogels, resulting long‐lived NIR emission 823 nm high donor/acceptor ratio, successfully applied cell labeling window.

Balancing the Chain Flexibility and Rigidity of Crosslinked Polyacrylic Acid Toward Optimized Fluorescence Quantum Yield

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

ABSTRACT The balance of chain flexibility and rigidity may improve the fluorescence quantum yields (QYs) unconventional aggregation‐induced emission (AIE) polymers. Herein, we prepared four crosslinked polyacrylic acids (CPAAs) with AIE effect using N,N′ ‐methylene bisacrylamide (MBA) as crosslinker. CPAAs decreases increase MBA contents. These show bright blue under irradiation UV light. maximum excitation wavelengths are not near their absorption peaks because is originated from clustering oxygen atoms carbonyl groups, but ( n , π *) transition atoms. spectra fluorescent lifetime data both validate that all have similar species. Density functional theory calculations suggest comes carboxyl groups. One balanced has an optimized QY 17.7%, which much higher than reported linear PAA 4.5%.
