Herein, a cobalt single atom is employed to construct N─Co─O charge transfer bridges (termed Co-ACTB) to facilitate charge separation in ZnIn2S4 and MIL-125-NH2 (ZIS/MIL) Z-scheme heterojunctions. Synchrotron radiation X-ray absorption spectroscopy suggests the successful construction of Co-ACTB by elucidating the atomic configuration and local coordination characteristics of Co species. Theoretical calculations reveal coexisting regions of charge depletion and accumulation enveloping N─Co─O configuration, confirming their function as effective charge-transfer channels. Co-ACTB obviously strengthen charge transfer and enhance photoelectric properties. Consequently, ZIS/Co/MIL achieves a peak photocurrent of −349.85 µA cm−2, representing 9.6-fold and 162.7-fold enhancements over those of ZIS/MIL and ZIS, respectively. Furthermore, a template reconstruction-mediated bidirectional cascade rolling circle amplification strategy is integrated with a Co-ACTB-based photoelectrode to afford a sensitive PEC sensing platform, exhibiting a linear response ranging from 0.1 fM to 10 nm with a detection limit of 0.34 fM. This work provides novel insights into utilization of SAMs to enhance carrier separation within heterojunctions, thereby enhancing PEC sensing performance.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"1 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209615","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}

This study introduces a jellyfish-inspired micro-meniscus solar evaporator (JMSE) designed to enhance evaporation efficiency, particularly in complex ocean environments contaminated with oil and subjected to wave action. Leveraging a 3D micro-meniscus architecture combined with bionic spring microchannels, the JMSE facilitates the continuous transport of water from the oil-water interface, achieving a remarkable evaporation rate of 2.16 kg m−2 h−1 under 1 sun—a 30% improvement over conventional solar evaporation systems. Moreover, the system exhibits robust salt-rejection capabilities, maintaining effective desalination even under challenging conditions, with an evaporation rate of up to 2.86 liters m−2 day−1 for a 5 wt.% NaCl solution. Most significantly, continuous operation over extended periods underscores the JMSE's resilience and efficiency, attaining exceptional purification from various saline sources while conforming to World Health Organization standards for drinking water.

Nevertheless, the blue QLEDs still suffer from subpar device performance compared to red and green counterparts. The deep energy level of blue QDs leads to inferior hole injection capability. Additionally, the small potential barrier between the core and shell facilitates carrier in blue QDs coupling with sulfur dangling bonds on the QD surface. Herein, phenethylammonium chloride (PEACl), a dipole molecule, is introduced to modify the surface of blue QDs. The replacement of long-chain oleic acid ligands with Cl- ions improves carrier transport, while the NH3+ group of PEACl passivates surface sulfur defects. Additionally, the large dipole moment of PEACl upshifts the energy levels, thereby enhancing hole injection efficiency in the devices. Consequently, the resulting devices based on PEACl-modified ZnCdSe/ZnCdS/ZnS QDs exhibit a record external quantum efficiency of 23.8%, a peak luminance of 42,724 cd m−2, and an extrapolated operational lifetime of 22,180 h at 100 cd m−2, significantly outperforming the control devices.

Optical microcavities improve spectral precision through high-quality factors but require complex reflector structures and simultaneous optical and electrical optimization. Here, a universal strategy is presented to achieve spectrally precise emission from broadband organic light-emitting diodes (OLEDs) by enhancing the Purcell effect through dual-microcavity resonances. A secondary cavity atop the OLED separates optical and electrical design while generating dual-microcavity resonances. Coupling between excitons and dual-microcavity enhances the Purcell effect, leading to an increased spontaneous emission rate. Spectrally tunable, ultrapure green emission (FWHM = 21 nm) is demonstrated from phosphorescent OLEDs (intrinsic FWHM = 60 nm), achieving ≈65% spectral narrowing. The devices also exhibit a high luminance of 1.241 × 105 cd m−2, strong directionality, and suppressed efficiency roll-off.

Nevertheless, realizing day-long organic persistent luminescence featuring angle-resolved afterglow color remains challenging. Herein, a day-long organic afterglow (DOA) system is developed by doping 9-(naphthalen-2-yl)-9′-phenyl-9H,9′H-3,3′-bicarbazole into polyethylene terephthalate. This system demonstrates a remarkably long afterglow (>24 h ambient, >100 h at 4 °C), ranking among the longest durations reported for polymeric afterglow materials. The DOA originates from radiative recombination of charge-separated radicals, which reform the emissive exciplex state. Importantly, this recombination is modulated by the donor/acceptor energy gap, and the cation radicals are stabilized by charge delocalization over the donor components. Furthermore, by integrating this long-persistent luminescent system into designed polymeric multilayer interference structures, iridescent afterglow color with distinct viewing-angle dependence is achieved. Based on the exciplex's broad emission, the angle-resolved DOA color exhibits wide spectral tunability, covering red, green, and blue hues, making it suitable for complex security features. Additionally, the system demonstrates exceptional mechanical flexibility and plastic- deformation-dependent optical properties, thereby expanding the potential of color-tunable organic afterglow materials for advanced applications in authentication technologies and optical security features.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"3 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209637","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}
