The conventional hybrid organic–inorganic (HOI) crystals often suffer from intrinsic limitations that hinder their performance. In contrast, our novel strategy employs a distinctive π-conjugated organic functional unit with an optimized push–pull configuration further integrated into a robust metal-halide framework. The novel crystal, namely, (C5H5N3O2)2ZnCl2 (2A5NPZC), represents a novel paradigm in HOI design and exhibits remarkable properties, including bulk crystal (15 × 7 × 4 mm3), giant refractive index difference (0.40 at 514 nm (exp)), a high third-order NLO susceptibility (χ(3) = 4.442 × 10–9 esu), excellent optical transmittance range (415–1400 nm), and superior optical limiting capability (6.3 mW/cm2 at 532 nm). Our findings highlight the broader potential of push–pull-type π-conjugated units as a versatile platform for the rational design of high-performance materials well-suited for advanced photonic technologies.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3087–3094"},"PeriodicalIF":8.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Photothermal superhydrophobic defrosting (PSD) surfaces have garnered considerable interest; however, the frost layer on the surface hinders the effectiveness of photothermal performance. Here, a zonal thermal management (ZTM) strategy is demonstrated to maximize the performance of PSD surfaces that are composed of hierarchical multilayer structures on the zonal millimeter-scale arrays. The peaks with a low solid–liquid area act as low-adhesion zones, and the valleys serve as effective photothermal heating zones. The heat spreader can rapidly transfer heat from heating valleys to the frost-covered peaks, while the thermal insulation layer minimizes heat loss to the cold substrate. Even under low temperatures and low solar intensities, the ZTM strategy prevents the surface from being completely covered by frost and enables photothermal heating to remove frost efficiently. The first demonstration of the ZTM strategy provides insights into designing efficient all-day antifrosting surfaces.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3065–3073"},"PeriodicalIF":8.7,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This design addresses the limitation of traditional photodetectors, which typically exhibit a narrow wavelength response range. By controlling the bias polarity, incident light of different wavelengths can be selectively detected in a single device. Under forward bias, the photodetector operates in a narrowband ultraviolet detection mode with a peak responsivity of 90.15 mA/W. Conversely, under reverse bias, it exhibits broadband detection from ultraviolet to near-infrared with an enhanced peak responsivity of 98.57 mA/W. The dual-mode response is generated by the combined action of the ZnO layer that absorbs ultraviolet light, the organic bulk heterojunction layer that absorbs light from ultraviolet to near-infrared, and the electron blocking layer PEDOT:PSS. This study presents a dual-mode photodetector with selective spectral response, offering potential applications in IoT, security sensing, and biological imaging.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3074–3081"},"PeriodicalIF":8.7,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we aimed to address the permeance-selectivity tradeoff inherent in conventional silica membranes by applying plasma surface modification to pendant-type silica membranes. We focused on the bulkiness of pendant groups and employed phenyl-functionalized silica membranes. The modification enabled precise control over the pore structure and hydrophilicity within a thickness of less than 20 nm, attributed to the decomposition of bulky phenyl groups performing like nano templates, resulting in the formation of Si–OH groups and Si–O–Si cross-links. Consequently, the plasma-modified membrane exhibited a high H2O permeance of 5.6 × 10–6 mol m–2 s–1 Pa–1 and H2O/EtOH permeance ratio of 5300 in pervaporation dehydration, overcoming the tradeoff. A novel strategy for producing highly porous ultrathin silica membranes by a facile process employing atmospheric-pressure plasma surface modification is proposed.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3058–3064"},"PeriodicalIF":8.7,"publicationDate":"2025-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsmaterialslett.5c00576","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the BBL OFETs, fabricated in 2003 and 2011, had excellent functionality, the figures of merit slightly degraded from their original values. Thermal annealing of the aged OFETs enabled a complete reversal of the degradation process and full recovery of the electron transport properties. Trap density of states spectral analysis and characterization of OFET performance as a function of thermal annealing show that the ambient air-induced trapping sites accumulated at the semiconductor/dielectric interface over the long term are fully passivated. Our results provide evidence of over 21-year ambient air stability of BBL OFETs and offer insights into the potential design of next-generation semiconducting polymers and organic electronic devices with excellent stability.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3049–3057"},"PeriodicalIF":8.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the biohybrid light-emitting diode (BioHLED) concept, replacing toxic and/or rare photon filters with classical β-barrel fluorescent proteins (FPs) that must withstand irradiation, temperature, oxidation, and dehydration stress, the question if FPs from extremophiles and/or living fossils might be better for lighting applications arises. We addressed this by introducing a thermostable prokaryotic FP, whose inherent promiscuity enables the design of tunable emitting proteins. Three milestones were reached: (i) a comprehensive phylogeny of phycobiliproteins from a large data set (182 proteins from 29 thermophiles) to identify the most versatile zombie-like phycobiliprotein (highly ancestral character), (ii) heterologous expression of this phycobiliprotein (SPritZ) in Escherichia coli and further enhancement via rational mutagenesis into a brighter and more thermal-resilient variant (eSPritZ), and (iii) 2.5-fold stable BioHLEDs comparing SPritZ vs eSPritZ in hydroxypropyl cellulose coatings.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 9","pages":"3041–3048"},"PeriodicalIF":8.7,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acsmaterialslett.5c00653","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144921078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
