Indoor Organic Photovoltaics with Over 29% Efficiency and Great Stability Enabled by Giant Dimeric Acceptors with Hypsochromic Absorption and High Glass Transition Temperature

Advanced Science, EarlyView.
Through a systematical investigation of structure‐performance relationship from the small‐molecule acceptor to giant molecule acceptors (GDAs) and polymer acceptor, a fluorinated GDA is reported with hypsochromic absorption and high glass transition temperature. The resulting devices demonstrate a remarkable efficiency of 29.1% under indoor conditions,

Sustained and Efficient Ethanol Oxidation by Tethering Tunable N‐Donors Onto Integrated MXene/Pd‐Electrodes

Advanced Science, EarlyView.
Three novel 3D layered integrated electrodes for Pd‐catalysed ethanol oxidation are developed; their innovative design features N‐heterocyclic amide linkers grafted on an MXene, co‐anchoring Pd nanoparticles via “hand‐in‐hand” coordination. The resulting well‐defined Pd (111) catalytic sites help achieve extremely stable long‐term cycling with ...

Selective Lithium Recovery via Stepwise Transition Metal Crystallization in a Natural Deep Eutectic Solvent

Advanced Science, EarlyView.
A biodegradable, natural deep eutectic solvent (DES) is designed for preferential lithium (Li) leaching from various cathodes under mild conditions (60 °C, 8 h). Compared to traditional acids and DESs, it achieves >96% Li leaching from black mass with minimal transition metal dissolution via a stepwise reduction, complexation, hydrolysis, and ...

Stretchable Fiber‐Based Organic Light‐Emitting Diodes Display Enabled by Robust, Conductive, and Deformable Via

Advanced Science, EarlyView.
A stretchable OLED fiber display is developed by introducing a novel robust, conductive, and deformable via (RCD‐via) that maintains electrical and mechanical integrity under strain. Through scalable integration and mechanical design, the display operates reliably even during stretching, offering a promising strategy for truly wearable textile ...

Rational Design of a Multifunctional MOFs for Alkane‐Selective Gas Separation

Advanced Science, EarlyView.
The design of a dimethyl‐functionalized adsorbent provides insight into the simultaneous separation of CH4/N2, C2H6/C2H4, and C3H8/C3H6 mixtures. Abstract Efficient separation of light hydrocarbons—including the removal of CH4 from N2 and the purification of olefins such as C2H4 and C3H6 from their corresponding alkanes (C2H6 and C3H8)—is critical in ...

Controlling Selectivity at the First Hydrogenation Level: Synthesis of 3‐Hydroxyisoindolines by Heterogeneously Silver‐Catalyzed Monohydrogenation of Phthalimides

Advanced Science, EarlyView.
3‐Hydroxylactams are obtained from phthalimides through a heterogeneous catalyzed chemoselective hydrogenation, able to stop the process at the first hydrogenation level. By using a rationally designed [Ag/Al2O3] recyclable solid nanocatalyst, a wide range of cyclic hemiamidals are accesed through a full atom‐economical reaction that preserves (hetero ...

Supramolecular Macrocyclic Iodine Adsorbents Enable Photothermally Stable Perovskite Solar Cells

Advanced Science, EarlyView.
Two novel diazapentacene‐based macrocycles are synthesized with expanded cavities that enable dual‐mode iodine adsorption through both physical and chemical interactions. When applied as iodine adsorbents in solar cells, PSCs incorporating M4 achieve 26.13% efficiency with 95.85% retention after 1000 h at 85 °C.

Metal–Organic Framework Featuring Monodispersed Silver Cation Sites for Highly Efficient and Selective Extraction of Aqueous Iodide Anions

Advanced Science, EarlyView.
A novel cationic metal–organic framework (MOF‐monoAg) featuring monodispersed silver (Ag+) sites is developed for the highly selective extraction of aqueous iodide ions (I−). MOF‐monoAg exhibits high accessibility, selectivity, and binding affinity toward I− ions, enabling superior iodine extraction from seawater and efficient iodide removal from ...
