Chiral Supramolecular Templating Enables Tunable Second‐Harmonic Generation in Hybrid Zinc Thiocyanates

Angewandte Chemie, EarlyView.
Chiral supramolecular templates derived from natural amino acids direct the spatial organization of SHG‐active [Zn(SCN)4]2− units, enabling diverse second‐harmonic generation in hybrid zinc thiocyanates. ABSTRACT Chiral organic molecules have been widely used to construct hybrid nonlinear optical (NLO) materials with second‐harmonic generation (SHG ...

Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

Angewandte Chemie, EarlyView.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

Stabilization of Ultrafast Domain Wall Motion by Edge‐Anisotropy Engineering in Ferrimagnetic Nanowires

Advanced Electronic Materials, EarlyView.
Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...
