Redefining the Minimal Editable Unit of Supramolecular Synthons: A 1→2 Lattice‐Editing Strategy in Ternary Multicomponent Crystals

Advanced Science, EarlyView.
Inspired by skeletal editing, we propose a lattice‐editing strategy that extends the minimal editable unit in supramolecular crystals from individual components to local supramolecular structural units, enabling non‐stoichiometric one‐to‐many substitution while preserving the parent lattice architecture.

Crystal structure and Hirshfeld surface analysis of 8-azaniumylquinolinium tetrachloridozincate(II)

Acta Crystallographica Section E Crystallographic Communications, 2023
The reaction of 8-aminoquinoline, zinc chloride and hydrochloric acid in ethanol yielded the title salt, (C9H10N2)[ZnCl4], which consists of a planar 8-azaniumylquinolinium dication and a tetrahedral tetrachlorozincate dianion. The 8-aminoquinoline moiety is protonated at both the amino and the ring N atoms.

Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

Advanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

Pressure‐Activated and Retained Blue Emission in Melamine Through Hydrogen‐Bond and Packing Regulation

Advanced Science, EarlyView.
Pressure treatment activates and retains bright blue emission in melamine (MA). The pressure‐modified hydrogen‐bonding network and molecular packing create a distinct local environment after decompression, changing the balance among competing excited‐state relaxation pathways and enabling retained emission.
