Flame‐Retardant Quasi‐Solid‐State Electrolytes From Self‐Assembled Azolate Hybrid Frameworks for Highly Safe Lithium Batteries

open access: yesAngewandte Chemie, EarlyView.
This work develops a spray‐assisted in situ assembly technique to construct AHF materials with nitrogen/oxygen‐regulated one‐dimensional channels on glass fiber, providing abundant active sites and enabling rapid transport for lithium ions. Subsequently, phosphate flame retardants are encapsulated via in situ polymerization, resulting in a thermally ...

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

open access: yesAdvanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

Metal Active‐Site Exposure via Ligand Engineering Boosts CO2‐to‐Ethylene Conversion on Cu18 Nanoclusters

open access: yesAdvanced Science, EarlyView.
Through quantitative ligand stripping of [Cu18H17(PR3)10]+ nanoclusters via intramolecular interaction modulation, selectivity for CO2 electroreduction to C2H4 is significantly enhanced. The weakly coordinating ligand triggers dual‐ligand stripping (FEC2H4 = 70.59%), whereas the strongly coordinating ligand results in single‐ligand retention (FEC2H4 ...

Photo‐Triggered, Fast, and Fluorogenic Thiophene‐Based Cycloalkynes for the Bioorthogonal Fluorescent Labeling of 1,3‐Dipole‐Tagged Molecules in No‐Wash Conditions

open access: yesAngewandte Chemie, EarlyView.
Thiophene is king! The fusion of thiophene rings to cycloalkynes super‐charged their copper‐free click chemistry applications, by (1) enhancing the alkyne reactivity (fastest cyclooctyne to date) and (2) rendering the alkyne fluorogenic (with fluorescence enhancement up to 150‐fold upon reaction), making these bioorthogonal reagents ideal for tracking ...

Nickel‐Catalyzed Three‐Component Difluoroalkylation‐Amination for the Direct Access to Anti‐Inflammatory β‐Difluoroalkyl Amines

open access: yesAdvanced Science, EarlyView.
A nickel‐catalyzed three‐component reductive fluoroalkylation‐amination strategy of N‐vinylamides for the direct access to the α‐amidyl‐β‐difluoroalkyl amines was reported here. The synthetic method features with broad substrate scope, mild conditions, high functional group tolerance, and convenience to handle.

A Mechanical Planar Chiral Rotaxane Induces Single‐Handed Helicity in a Twisted Perylene Diimide

open access: yesAngewandte Chemie, EarlyView.
A mechanical planar chiral rotaxane (Rmp) is used to induce single‐handed helical chirality (M) in a perylene diimide chromophore, resulting in persistent circular dichroism (CD) and circularly polarised luminescence (CPL). ABSTRACT The twisting of chromophores such as perylene diimides (PDIs) into helical structures affords chiroptical properties from

Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Hyperpolarization of Pyridine 15N‐Oxide Molecular Probes Enabled by Parahydrogen

open access: yesAngewandte Chemie, EarlyView.
Pyridine 15N‐oxides are introduced as motifs for hyperpolarization studies and biochemical applications are demonstrated. ABSTRACT Magnetic resonance (MR) is a powerful non‐invasive technique for probing structural, functional, and metabolic processes with high spatial and temporal resolution.
