Two small molecule CILs, PDINN‐TS and PDINN‐BS are developed, by modifying the bay sites of perylene diimide (PDI) with thieno [3,2‐b] thiophene and 2,2′‐bithiophene, separately. Due to better electron‐donating capacity and longer conjugate length of the 2,2′‐bithiophene, PDINN‐BS exhibits a stronger self‐doping effect and superior interface compatibility compared to PDINN‐TS. Consequently, in PM6: Y6 OSCs, PDINN‐BS achieved an elevated PCE of 16.95%, surpassing PDINN‐TS of 16.66%. Meanwhile, PDINN‐BS exhibits excellent universality. When employing PM6: BTP‐eC9 and PM6:L8‐BO systems, PDINN‐BS‐based device yielded PCE of 18.02% and 18.95%, outperforming PDINN‐TS of 17.51% and 18.38%, respectively. Furthermore, stability tests revealed that after being stored in the glovebox for 1500 h, PDINN‐BS retained 90% of its pristine PCE, compared to 86% for PDINN‐TS. PDINN‐BS showed longer 80% PCE decay (T80) of 150 h in air, 200 h at 70 °C heating in N2, and 500 h under 1 sun immersion, surpassing PDINN‐TS with 120, 130, and 380 h, respectively. This demonstrates that PDINN‐BS displayed superior stability under a complicated environment. Consequently, this study provides significative guidance for the exploitation of high‐performance and high‐stability OSCs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"286 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887102","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}

In this study, selenium is incorporated as a synergistic redox active center of oxygen to improve the stability of Na‐ion cathodes. The redesigned cathode maintains stable voltage by demonstrating reversible oxygen redox while significantly suppressing the redox activity of manganese. The anionic redox contribution capacity of the selenium‐doped Na0.6Li0.2Mn0.8O2 cathode remains as high as 84% after 50 cycles, while the pristine Na0.6Li0.2Mn0.8O2 cathode experiences a reduction to 39% of its initial capacity. The X‐ray photoelectron spectroscopy data and computational analysis further revealed that selenium doping participates in redox as Se+4/5 which stabilizes the charged state and increases the energy step for O─O dimerization, thus improving the stability and lifespan of Na0.6Li0.2Mn0.8O2 cathodes.

Nevertheless, its unsatisfactory kinetic performance and cycling stability, along with its controversial energy storage mechanism, hinder its commercial application. Herein, the MnSe microspheres with Se‐rich vacancies (VSe‐MnSe) are synthesized, and employed as a cathode for Zn‐ion batteries/capacitors (ZIBs/ZICs) for the first time. Density functional theory (DFT) calculations and kinetic analyses illustrate that vacancy engineering of MnSe enhances the active sites, improves the electronic conductivity and ion transport, and reduces the adsorption energy and diffusion energy barriers of H+ and Zn2+, endowing the VSe‐MnSe cathode of ZIBs with significantly enhanced specific capacity, rate capability, and cycling stability. Interestingly, ex situ tests confirm the stable existence of VSe‐MnSe during the whole charge/discharge process and store energy with the first H+ insertion and subsequent H+/Zn2+ co‐insertion. More encouragingly, the VSe‐MnSe//porous carbon (PC) ZICs exhibit an ultrahigh energy density (178.0 Wh kg−1), a high power density (10 kW kg−1), and eminent cyclic stability (up to 10000 cycles).

However, due to the infinite degrees of freedom in soft materials, more efficient design methods for magnetic soft materials need to be explored. Here, a multimodal unit programming method is proposed for designing hard magnetic soft materials. The structure of the multimodal units is inspired by the segmented structure of earthworms. By altering the combination of single‐tube units, the dual‐tube units exhibit specific deformation modes. This approach simplifies the complex deformation of magnetic soft materials into the single deformations of units, enabling facile programming design of magnetic soft materials. The application of different deformation modes is demonstrated in various scenarios and scale down the units to one‐tenth of their original size for operations at different scales.

Despite their superior potential, high‐performance all‐QD homojunction photodiodes with bifacial structures have yet to be reported. Here, post‐treatment ligand engineering is successfully employed to precisely tune the doping dipoles of PbS QDs, transitioning them from n‐type, through intrinsic, to p‐type. All‐QD homojunction photodiodes solar cells with a n‐i‐p architecture are constructed by integrating three types of PbS QD layers of 1.37 eV bandgaps with controllable doping dipoles, which delivers a power conversion efficiency of 10.0%, among the highest values reported in PbS all‐QD homojunction solar cells so far. Owing to symmetry all‐QD architecture, bifacial PbS all‐QDs photodiodes, using 1.37 eV bandgap PbS QDs as both n‐type and p‐type charge transport layers and 0.90 eV bandgap PbS QDs as intrinsic light absorber layers, achieved an almost ideal bifactor approaching 93% and decent detectivities of 1.63 × 1011 Jones from ITO illumination and 1.86 × 1011 Jones from silver nanowire (Ag NW) illumination at 1370 nm.

However, there is a lack of an efficient strategy to regulate the selectivity of the BA conversion products. Here, by a simple cocatalyst engineering technique, the selective conversion of BA over Zn2In2S5 nanosheets (ZIS) is maneuvered. Two types of cocatalysts, i.e., Pt and Cd, are photo‐deposited onto ZIS that can shift the selectivity to diverse products, namely, Pt to benzaldehyde (BAD) and Cd to the carbon‐carbon (C─C) coupling compounds. Mechanistic studies indicate that Cd has a high reducing capacity to convert BAD back to the ketyl radical (C𝛼 radical), favoring the construction of the C─C bonds. Pt, however, facilitates the generation of C𝛼 radicals but is energetically unfavorable for their coupling reactions, resulting in the generation of BAD as the main product. Theoretical calculation reveals that the distinct catalytic behaviors of Pt and Cd stem from their different electronic structures that govern the adsorption strength to the reaction intermediates and the reaction energy barriers of the C─C coupling step. This work not only addresses the challenge of selectivity regulation for BA conversion but also brings fresh mechanistic insights into the role of the cocatalysts.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"58 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142887104","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}

For supercapacitors, the preferred carbon materials should own high specific capacitance, nice rate performance, large density, low self-discharge, and high mass-loading, which could be accomplished by sub-nanometer pores (0.5–1.0 nm). Herein, a new method of using carbon dots (CDs) as self-templates is reported to produce porous carbon with uniform pore diameters of 0.64–0.80 nm. As a result, the optimal sample with a high packing density (0.81 g cm−3) displays outstanding capacitances (gravimetric 515.5 F g−1, areal 5.16 F cm−2, and volumetric 417.6 F cm−3 respectively at 1 A g−1) at the commercial-level mass-loading of 10 mg cm−2. The assembled high-loading symmetric supercapacitor shows a high energy density of 22.3 Wh kg−1 at 3500 W kg−1, as well as a long cycle stability (99.9% of retention rate after 10 000 cycles at 2 A g−1) in an ultrawide voltage range of 1.4 V with aqueous electrolytes.

The conjugated backbones offer orderly aligned electron-rich nitrogen atoms to chemically react with the quaternary amine cation-pendants for creating a space conjugation, serving as a fluorescence sensing site in polar solvents. In low-polarity solvents, conjugated chains tend to twist and aggregate, accompanied by the space-conjugation enhancement.

Molecular dynamics (MD) simulations reveal that this molecular structure consists of multilevel strong and weak dynamic bonds: weaker coordination bonds and hydrogen bonds endow this sensor with exceptional sensitivity to minor strains, while stronger ionic bonds ensure superior mechanical properties. This meticulous molecular design enables the PAV/Cu2+‐CB‐x to exhibit a tensile strength of 7.16 MPa, an elongation at break of 355.50%, high conductivity of 0.294 S cm−1, and excellent sensitivity under the strains below 5% (gauge factor = 8.24). Additionally, this PAV/Cu2+‐CB‐x demonstrates a remarkable tensile strength recovery rate of 95.35% after multiple recycling. When applied as a strain‐responsive sensor, it can precisely capture movements of human joints and throat activity.
