Our findings reveal that natural cellulose stands out due to its exceptional water resistance, high adsorption energy, strong hydrogen bonding with ZnO, and a morphology that effectively prevents water molecules from penetrating the ZnO surface. Consequently, the ZnO/cellulose device retains 80% of its initial power conversion efficiency (T80 lifetime) for 2030 hours under humid aging conditions at 25 °C and 40% relative humidity (RH). Moreover, cellulose exhibits excellent interfacial compatibility with both the active layer and ZnO, leading to an impressive T80 lifetime of 2712 hours under thermal aging at 75 °C in N2. The ZnO/cellulose device also demonstrates remarkable resilience under harsher conditions, maintaining a T80 lifetime of 572 hours when stored at 75 °C and 50–60% RH.

However, current research on dimeric photovoltaic materials primarily focuses on acceptors, while the studies on dimer donors have been relatively limited. In this study, we designed and synthesized three porphyrin dimer donors E-ZnP2, BT-ZnP2 and BDT-ZnP2 by linking two functionalized D–A (D: electron donor unit and A: electron acceptor unit) porphyrins with ethynylene, diethynylene-benzothiadiazole (BT) and diethynylene-benzodithiophene (BDT), respectively. The impacts of the linking units on their energy levels, absorption properties, aggregation behaviors and photovoltaic performance are investigated. Among the three devices with porphyrins as the electron donors and Y6 as the electron acceptor, the E-ZnP2-based cells exhibit superior charge mobility and reduced charge recombination due to the stronger molecular aggregation of E-ZnP2 and the improved miscibility with Y6, resulting in an impressive power conversion efficiency (PCE) of 9.64%. The findings offer valuable guidelines for developing dimer donor materials.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 13","pages":" 6880-6887"},"PeriodicalIF":5.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A custom-synthesized ethynyl parylene dielectric layer is fabricated using chemical vapor polymerization, which yields smooth conformal films. Four types of azide materials – benzyl azide, aminopropyl azide, trimethylsilyl azide, and biotin-PEG3-azide – are utilized as dielectric constant modulators via click reactions. With only approximately 1% surface modulation, the dielectric constant of ethynyl parylene is nearly double that of pristine ethynyl parylene, whereas the leakage current density remains unchanged. Finally, IGZO TFTs are successfully fabricated using surface-modulated ethynyl parylene as the gate dielectric. Therefore, the click reaction of a polymer gate dielectric is an effective method to tune its properties while maintaining the interface properties of the front channel.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 13","pages":" 6614-6623"},"PeriodicalIF":5.7,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-quality hBN nanoribbons were synthesized from a boric acid and melamine precursor via a thermal process, followed by chemical vapor deposition (CVD) of nickel using nickelocene. Optimal deposition occurred at 190 °C, as identified by gas chromatography (GC), with initial nickelocene decomposition starting at 100 °C due to interactions with hBN's surface functional groups. Characterization techniques—including Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analysis, field emission scanning electron microscopy (FESEM), inductively coupled plasma optical emission spectroscopy (ICP-OES), and vibrating sample magnetometry (VSM)—confirmed the successful formation of nickel nanoparticles on hBN. XRD revealed well-crystallized nickel in the 10 wt% Ni/hBN sample, while BET analysis indicated a reduction in specific surface area from 657 m2 g−1 to 580 m2 g−1 due to nickel-induced pore blockage. FESEM showed uniformly distributed spherical nanoparticles ranging from 30 to 50 nm in diameter, with elemental mapping confirming their dispersion. VSM analysis demonstrated enhanced magnetic properties with increased nickel loading, achieving a saturation magnetization of 1.85 emu g−1 and coercivity of 150 Oe at 10 wt% Ni/hBN. This work underscores the transformative potential of CVD in engineering the magnetic properties of Ni/hBN composites, paving the way for cutting-edge technological advancements.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 13","pages":" 6823-6830"},"PeriodicalIF":5.7,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143716588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our research, we investigated the impact of different polymer matrices, i.e. polystyrene, poly(methyl methacrylate) and a polystyrene–polybutadiene–polystyrene triblock copolymer, on the self-assembly into J-aggregates and the fluorescence quantum yield of the dye-matrix materials for spin-coated films. The degree of self-assembly of PBIs could be controlled by the PBI concentration, the type of polymer matrix, and an annealing process after spin-coating. Notably, the J-aggregates in a polystyrene matrix showed significant differences in their fluorescence quantum yield, which we attribute to transitions between individual one-dimensional fibers and the formation of larger three-dimensional crystallites.","PeriodicalId":84,"journal":{"name":"Journal of Materials Chemistry C","volume":" 12","pages":" 5981-5987"},"PeriodicalIF":5.7,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
