Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes
Advanced Materials, EarlyView.Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Application of Chiral Lanthanide-induced Shift Reagents to Optically Active Cations: the Use of Tris[3-(trifluoromethylhydroxymethylene)-( + )-camphorato]europium(III) to Determine the Enantiomeric Purity of Tris(phenanthroline)ruthenium(II) Dichloride [PDF]
, 1984 In non-polar solvents, chiral europium complexes provide attractive n. m. r. shift reagents to resolve spectra of optically active cations, and, in particular, for tris(phenanthroline)ruthenium dichloride,^1H n. m. r. shift differences of up to 0.7 p.p.m.

Chirality Transfer via Orientational Order of Micellar Assemblies on Gold Nanocrystals
Advanced Materials, EarlyView.A mechanism for chiral growth of Au nanocrystals mediated by orientational order of chiral micelles at seed surfaces is demonstrated. 3D electron microscopy and molecular dynamics simulations reveal how alignment of the micelles along crystal directions and torsion–orientation coupling govern chirality transfer, providing a framework to rationalize ...

Steering the Shape‐shifting of Bullvalene‐PdII Complexes Through Steric and Geometric Strain
Angewandte Chemie, EarlyView.This study explores the use of bis‐pyridyl substituted bullvalenes as dynamic shape‐shifting ligands within cis‐capped PdII complexes. The ring position of the pyridyl nitrogen is critical, leading to a range of Pd2L2 metallacycles and simple PdL complexes, each with distinctive bullvalene isomer preferences (represented in the figure by A‐D isomer ...

Advanced Optical Materials, EarlyView.We report a series of Au(III) complexes incorporating asymmetric carbazolyl motifs that regulate co‐facial distance between donor and acceptor moieties. Femtosecond transient absorption and density functional theory computation analyses reveal rapid reverse internal upconversion from the lowest triplet state (T1) to a thermally accessible higher‐lying ...

Predicting and Rationalizing Piezoelectricity in Racemic Bioorganic Molecular Crystals
Angewandte Chemie, EarlyView.Racemic molecular crystals, composed of equal mixtures of chiral enantiomeric components, are predicted to exhibit significant piezoelectric responses and favourable mechanical flexibility. This study identifies organic and bioorganic racemates as promising candidates for sustainable, lead‐free materials, enabling next‐generation applications in energy

Chiral particle separation by a non-chiral micro-lattice
, 2012 We conceived a model experiment for a continuous separation strategy of chiral molecules (enantiomers) without the need of any chiral selector structure or derivatization agents: Micro-particles that only differ by their chirality are shown to migrate ...
