Redefining the Minimal Editable Unit of Supramolecular Synthons: A 1→2 Lattice-Editing Strategy in Ternary Multicomponent Crystals. [PDF]

Adv Sci (Weinh)
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.
