Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

open access: yesAngewandte Chemie, EarlyView.
Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

A Descriptor for Non‐Arrhenius Ion Transport Enables Design of Sulfide Superionic Conductors

open access: yesAngewandte Chemie, EarlyView.
A curated database of sulfide electrolytes reveals widespread non‐Arrhenius ion transport. Meyer–Neldel deviation (MND) quantifies this behavior, distinguishes low‐conductivity and superionic regimes, and guides composition screening. An experimentally validated candidate exhibits room‐temperature conductivity of 7.21 mS cm−1, an apparent activation ...

Easy Access to Experimental Bond Dissociation Energies in Solution Using 2D‐IR Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
How strong is a chemical bond? The answer is hidden in the spacing of vibrational levels. This anharmonic fingerprint yields the energy needed to break an X─H bond from a single measurement, turning an ultrafast observable into a thermochemical quantity directly in the solvent of interest.

Rare‐Earth Multivariate Metal–Organic Frameworks: Cationic Radius Biased Compositional Control and Property Tuning

open access: yesAngewandte Chemie, EarlyView.
A family of multivariate metal–organic frameworks, UoB‐116(Ln), can be prepared using up to 16 different metals, revealing the ability to tune properties through compositional control. ABSTRACT The synthesis of a multivariate metal–organic framework (MTV‐MOF) family, [Ln(DNNDI)1.5]n (UoB‐116), is reported (DNNDI: N,N'‐bis(dinicotinate)‐1,4,5,8 ...

Polyproline: A Synthetic Polypeptide With Unique Properties

open access: yesAngewandte Chemie, EarlyView.
Poly‐L‐proline is a unique polypeptide distinguished by its well‐defined secondary structures and unusual thermal behavior. This mini review highlights recent advances in the synthesis of poly‐L‐proline by N‐carboxyanhydride (NCA) polymerization, the formation of structurally defined architectures and nanostructures, and emerging strategies that ...
