While initially explored to overcome the efficiency limit of single-junction photovoltaics, SF is now recognized as a broader platform for engineering correlated excited states. Efficient triplet generation and spin-correlated pairs create opportunities in photovoltaics, photodetection, photocatalysis, photon up-conversion, quantum light sources, spin-photon interfaces, and bioimaging. This Review summarizes the fundamental mechanisms, energetic requirements, and molecular design principles governing SF, together with the influence of supramolecular organization and external stimuli on its dynamics. Particular emphasis is placed on the multiscale relationships among molecular energetics, excited-state character, molecular packing, triplet-pair separation, triplet transport, and interfacial energy or charge transfer, which ultimately determine device performance. We further discuss recent advances in SF-enabled optoelectronic and quantum applications. Despite rapid progress, major challenges remain in establishing a unified mechanistic framework, understanding SF in polymeric and disordered systems, and expanding the library of stable, high-performance SF materials. Finally, we highlight future opportunities in machine-learning-assisted materials discovery, excited-state engineering, and the integration of SF into next-generation functional optoelectronic devices.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e74838"},"PeriodicalIF":29.1,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biexcitons are conventionally understood to radiatively decay more rapidly than excitons. This view stems largely from studies in strongly confined quantum dots (QDs), where inter-exciton correlations are often neglected. In contrast, weakly confined systems such as large CsPbBr3 QDs exhibit significant Coulomb correlations, necessitating a revised framework for biexciton radiative dynamics, one that has remained incomplete due to limited experimental insights. Here, we combine single-particle photoluminescence (PL) spectroscopy with effective-mass variational quantum Monte Carlo (VQMC) simulations to directly probe the biexciton geometry, exciton-phonon interactions, and radiative decay in CsPbBr3 QDs across a range of sizes and temperatures. We reveal that the biexciton-to-exciton radiative decay lifetime ratio is strongly modulated by inter-exciton correlations, with a striking inversion of the expected decay lifetime hierarchy in the weak-confinement regime. Specifically, at cryogenic temperatures, biexcitons exhibit anomalously longer radiative lifetime (148 ± 30 ps) than excitons (106 ± 16 ps), challenging conventional models. These findings uncover a correlation-driven regime of multiexciton physics and suggest new routes for tailoring light-matter interactions for classical and quantum photonic applications.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e74849"},"PeriodicalIF":29.1,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a molecularly engineered polyoxometalate-functionalized mesoporous metal-organic framework (meso-MOF@POM) nanoarchitecture that simultaneously reinforces the hydrogel network and enhances interfacial charge kinetics. The meso-MOF serves as a hierarchical scaffold with multiscale channels for polymer anchoring, while the sub-nanometer Keggin-type POM layer creates abundant redox-mediated electron transfer pathways. Upon integration of meso-MOF@POM into a dual-network poly(acrylic acid)/polyacrylamide hydrogel, the composite hydrogel enables high stretchability (>1000% strain), minimal electrical creep (<0.13% s-1@100% strain), and good cyclic durability (>3000 cycles). Crucially, the engineered organic-inorganic interface endows the hydrogel with excellent pseudocapacitive charge-transfer kinetics, which achieves low skin-electrode impedance (64 kΩ at 1 Hz vs. 287 kΩ at 1 Hz for Ag/AgCl gel). As a result, the skin-interfacing electrode enables high-fidelity recording of on-skin electrophysiological signals, including electrocardiogram, electromyogram, and electrooculogram, with an enhanced signal-to-noise ratio (e.g., 23.8 dB for ECG vs. 21.3 dB for Ag/AgCl gel).

However, conventional hydrogels rely on exogenous photothermal agents, which may compromise water transport and complicate heat transfer within the hydrogel under conditions of high loading, insufficient dispersion, or poor interfacial compatibility. To address those critical issues, we have presented a facile and modular strategy for constructing robust allomelanin bulk hydrogels, where photothermal precursors (1,8-dihydroxynaphthalene) act as crosslinkers to directly couple with hydrophilic polymers (oxidized polysaccharides) for hydrogel gelation, while serving simultaneously as functional monomers that undergo spontaneous reactions to in situ form photothermal agents during the curing process. This strategy avoids the introduction of exogenous photothermal agents while achieving seamless integration of the in situ-generated photothermal agents with the hydrogel network, thereby remarkably boosting the performances of water transport, water activation, and thermal management. The resulting allomelanin bulk hydrogel interestingly achieved an impressive evaporation rate of 4.26 kg·m-2·h-1 under 1 sun irradiation. Moreover, techno-economic analysis estimated a competitive clean water production cost of $1.66 per ton for the hydrogel, rivalling reverse osmosis.

In this study, we demonstrate that these voltage ripples originate from spatially heterogeneous electric field distribution within the mechanically deformed region. By using polarized electric fields formed through hydrogen bonding networks in MXene additive electrolyte, we can effectively homogenize the distribution of the electric field, thereby attenuating voltage ripples and smoothing the voltage curves. Moreover, the uniform electric field distribution promotes uniform Zn deposition and extends the device lifespan. As a result, the fabricated Zn-ion-based structural hybrid supercapacitor (CSHS) with MXene additive electrolyte exhibits a capacity retention of 93.6% after 10 000 three-point bending cycles at a strain of 0.5%, much higher than that of CSHS without the addition of MXene (80.4%).

In this work, we propose a binding-weakening electronic modulation strategy that balances CO2 activation and MgC2O4 release for greatly enhancing the reversibility of Mg-CO2 batteries. We demonstrate that the fault-twinned PdRh bimetallene, where Rh incorporation downshifts the Pd d-band center for weakening oxalate adsorption and Rh-derived conduction states enhance CO2 activation, can well catalyze the reversible CO2 conversion. Meanwhile, strain fields from abundant stacking faults create undercoordinated Pd sites that facilitate CO2 → C2O4 2- conversion. This dual regulation stabilizes the oxalate pathway that previous catalysts could not sustain for achieving ultrastable cycling over 700 h with minimal polarization (1.10 V discharge, 1.21 V charge), which represents a benchmark for both durability and energy efficiency among Mg-CO2 batteries.
