Sustainable Electrochemical Strategy for Selective Double Bond Oxidation in the Presence of Aldehyde Groups with Mo─N─O Catalysts

open access: yesAdvanced Science, EarlyView.
In this work, an electrochemical strategy employing hydroperoxyl radicals and a molybdenum‐based catalyst (Mo─N─O) enables selective double‐bond oxidation in cinnamaldehyde, preserving aldehyde integrity. Under mild, energy‐efficient conditions (−200 mA), this approach converts cinnamaldehyde to benzaldehyde with complete conversion (100%) and >99 ...

SuFEx‐Enabled Catalytic Synthesis of Fluorescent Organosulfur Polymers for the Rapid Detection of Explosives

open access: yesAdvanced Science, EarlyView.
Rapid detection of explosives is essential for public safety and national security. Here, conjugated polymers (SPs), incorporating pentiptycene with organosulfur side chains, have been reported using sulfur(VI)‐fluoride exchange (SuFEx). The SP‐7 polymer exhibited exceptional fluorescence quenching (>99% in 60 s) for detecting nitroaromatic explosives.

Confinement‐Induced Metastable Supramolecular Assembly: Dynamic Built‐in Electric Field Driving Deep Mineralization of Organic Pollutants

open access: yesAdvanced Science, EarlyView.
Utilizing the 2D confined space of layered double hydroxide (LDH), living supramolecular assembly (LSA) are successfully prepared with smaller intermolecular distances than in crystals. The IEF enhancement value can reach 11.8 times, which induces a charge separation efficiency of 71.52%.

Deterministic Fabrication of Plasmonic Nanostructures on Optical Nanofibers via Blurred Electron Beam Deposition

open access: yesAdvanced Science, EarlyView.
A nanofabrication method enabling the direct growth of plasmonic nanostructures are presented on suspended tapered optical nanofibers via Blurred Electron Beam Induced Deposition (BEBID). By defocusing the beam to reduce mechanical stress, BEBID achieves sub‐20 nm precision and structural control, enabling directional scattering and light–matter ...

Atypical Hydrogen Bond Interaction Enables Anion‐Rich Solvation Structure in Polymer Electrolytes for High‐Voltage Flexible Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A high‐voltage, Li‐metal‐compatible, and highly conductive polymer electrolyte is reported by integrating a low‐solvating fluorinated plasticizer. Strong atypical hydrogen bonds formed between the plasticizer and polymer chains promote the establishment of anion‐rich solvation structure, effectively stabilizing electrolyte‐electrode interphase at the ...

Zwitterion‐Stabilized Superlattices and Frank‐Kasper Phases in Charged Block Copolymers for Mechanically Robust Dielectric Soft Materials

open access: yesAdvanced Science, EarlyView.
Superlattices formed by the co‐assembly of acid‐functionalized block copolymers and zwitterions exhibit tunable morphologies, transitioning from lamellae to cylinders to Frank‐Kasper phases. Zwitterion interfacial localization enhances dielectric constant, mechanical strength, and thermal stability, making these materials promising for soft electronics
