Atomic Precision CoCu Heterodimers with Pseudo‐D3h Symmetry Enable Tandem Nitrate Reduction

open access: yesAdvanced Science, EarlyView.
The Co─Cu heterodimer anchored on nitrogen‐doped graphene oxide substrate facilitates electrochemical nitrate reduction in alkaline medium. Co site promotes water dissociation to supply a proton, while Cu sites enhance nitrate adsorption and activation.

Conformation‐Modulated Lignin for Durable and High‐Output Cellulosic Triboelectric Materials Toward Self‐Powered Sensing

open access: yesAdvanced Science, EarlyView.
Conformation‐engineered alkali lignin with flexible aliphatic side chains is integrated into cellulose to suppress tribo‐induced fiber fibrillation and interfacial wear. Dynamic chain adaptability enhances frictional energy dissipation and dielectric polarization, enabling durable, high‐output triboelectric sensing with excellent recyclability and ...

Dual Effect of Steric Hindrance in Non‐Aqueous Amine Absorbents: Navigating the Trade‐Off Between Kinetics and Thermodynamics for Efficient CO2 Capture

open access: yesAdvanced Science, EarlyView.
This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.

A Noncovalent Click‐to‐Release Strategy to Control Bond Cleavage and Prodrug Activation

open access: yesAngewandte Chemie, EarlyView.
Extending the click‐to‐release concept beyond covalent ligation, we introduce a noncovalent click‐to‐release strategy based on cucurbituril‐adamantane (CB‐Ad) association. A supramolecular preassembly encapsulating a self‐immolative guest (SIG) is rationally designed to prevent premature release, while adding a high‐affinity Ad guest initiates the CB ...

Beyond Silicon: Toward Sustainable, NIR‐II, and Conformable Organic Photodiodes

open access: yesAdvanced Energy Materials, EarlyView.
In this perspective, a strategic shift in organic photodetector (OPD) research is proposed: instead of the incremental advances in silicon's stronghold arena, the most impactful future for OPDs lies in addressing silicon's intrinsic limitations, i.e., detection in the longer wavelength range above silicon's coverage (>1100 nm, termed as near infrared ...

Tuning Circular Dichroism and Circularly Polarised Luminescence in Single Crystals of a Perylene Diimide Macrocycle

open access: yesAngewandte Chemie, EarlyView.
The circular dichroism (CD) and circularly polarised (CPL) of a bis‐perylene diimide macrocycle are measured in single crystals. These chiroptical properties are tuned by the macrocycle's π–π stacking interactions in the solid‐state. Abstract Chiral materials that manipulate circularly polarised light have burgeoning applications across optoelectronics,
