Ordered Ionic‐Liquid Channels Enable Fast Anhydrous Proton Conduction at up to 240°C for Fuel Cells

Angewandte Chemie, EarlyView.
Infiltration of ionic liquids into a composite scaffold comprised of graphene and boron nitride nanosheets functionalised with positively charged polyethyleneimine produces robust proton conducting membranes for the intermediate temperature electrochemical devices.

Fundamental Understanding of Oxidative Stability in Fluorinated Asymmetric Ethers for Li Batteries

Angewandte Chemie, EarlyView.
To improve Li‐metal battery electrolytes, we analyze fluorinated 1‐ethoxy‐2‐methoxyethane (FxEME) oxidative stability via density functional theory (DFT) and molecular dynamics (MD). Fluorination strengthens ethoxy C–H bonds and alters solvent orientation at the cathode, weakening interfacial interactions.

Carbohydrate Physicochemical Properties: The Innate Hydrogen Bond Donating Capacities of α‐Glucoside and α‐Galactoside Alcohol Groups

Angewandte Chemie, EarlyView.
Experimental determination of the innate hydrogen bond donating capacities of the glucose and galactose non‐anomeric alcohols revealed significant variations depending on position and relative configuration, which were quantified on the pKAHY scale, relevant for MedChem purposes, hence providing another tool toward rational glycomimetic development ...

3‐Deoxy‐3‐Fluoro Mannuronic Acid Alginates: Stereoselective Automated Synthesis and Conformational Behaviour

Angewandte Chemie, EarlyView.
The impact of C‐3 fluorination on the synthesis and conformation of alginate oligosaccharides is investigated. A C‐3‐fluoro mannuronic acid building block is generated and shown to react with high β‐selectivity. Automated glycan assembly enables access to uniquely fluorinated mannuronic acid alginates where deoxyfluorination is shown not to perturb the

CSAKD: Determining Absolute Ligand Affinities From 19F NMR Chemical Shift Anisotropy

Angewandte Chemie, EarlyView.
Affinity determination is crucial in drug discovery, yet remains difficult for weakly binding fragments. We introduce chemical shift anisotropy KD$K_{\text{D}}$ (CSAKD) by 19F$^{19}{\rm F}$ NMR relaxation experiments, a titration‐free method that requires no isotopic labeling.
