Bypassing Pre‐Photoactivation in High‐Barrier Polyamide for Robust and Scalable Organic Persistent LuminescenceABSTRACT The critical trade‐off between ambient stability and moisture/oxygen barrier properties has long hindered the practical application of organic persistent luminescent (OPL) polymers, particularly for rapid‐response photoluminescence in demanding environments. Such limitations are manifested in direct‐doping systems, which suffer from humidity‐induced mechanical deterioration and sluggish excitation kinetics. Here, we overcome this fundamental limitation by molecularly locking chromophores within a poly( m‐ xylene adipamide) (MXD6) matrix via melt doping. The engineered OPL composites leverage MXD6's exceptional barrier (oxygen transmission rate (OTR): 0.68 cm 3 ·m −2 ·day −1 ·bar −1 ; water vapor transmission rate (WVTR): 5.3 g·m −2 ·day −1 ) to achieve efficient multicolor afterglow with high quantum yields ( Φ afterglow = 30.6%) and long lifetimes (5.6 s), operating stably without pre‐photoactivation. Remarkably, they retain >90% of afterglow efficiency after 30 days of continuous water immersion. Integrated experimental and computational studies reveal that multiple disordered hydrogen bonding simultaneously rigidify the polymer matrix and interlock chromophores, establishing an oxygen and water barrier for triple excitons. This strategy enables meter‐scale homogeneous fibers and transparent films that validate industrial viability for versatile luminescent devices. This work offers a universal paradigm for ambient‐stable OPL polymers, solving the stability‐barrier trade‐off to unlock rapid‐response luminescence in demanding environmental applications. 10.1002/advs.7615101.07.2026 Host-Guest interactions in supramolecular chemistry2026-07-02 20:05:49

A Broadly Generalizable Dye for Colorimetric Aptamer-Based SensorsHigh Resolution Image Download MS PowerPoint Slide Aptamer-based dye-displacement assays offer a simple, rapid, and robust approach for detecting analytes via a visible color change. These assays utilize a dye molecule that binds to aptamers in a monomeric or dimeric form; target binding to the aptamer subsequently displaces the dye, which aggregates in solution and undergoes a marked shift in absorbance. However, the generalizability of these assays remains an open question, and it is unclear whether existing dyes are broadly capable of binding to and undergoing target-induced displacement from diverse aptamers of varying sequence and structure. Here, we evaluate the compatibility of a panel of 105 diverse small-molecule-binding DNA aptamers with dye-displacement assays based on two commonly used cyanine dyes: 3,3′-diethylthiatricarbocyanine (Cy7) and 3,3′-di(3-sulfopropyl)-4,5,4′,5′-dibenzo-9-methyl-thiacarbocyanine (MTC). We found that roughly half of the aptamers tested were incompatible with these dyes. Through extensive evaluation of a large dye library, we identified X-732-91B─an asymmetric cyanine dye that displays unprecedented generalizability in dye-displacement assays. This dye worked with 95% of our 105-member panel of aptamer-target pairs, producing a measurable signal within seconds. This discovery could enable ‘plug-and-play’ development of aptamer-based colorimetric sensors for a wide range of targets in applications including medical diagnostics, environmental monitoring, quality control, and forensics.10.1021/jacsau.6c007032026-06-29 Host-Guest interactions in supramolecular chemistry2026-06-30 20:07:39
