Rediscovering Sodium Ionophores as Selective Agents for Lithium Recognition and Extraction
Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.Long‐classified sodium ionophores unexpectedly prefer lithium and act as efficient extractants in solid–liquid extraction (SLE). Readily prepared from catechol and haloacetamides, these hosts recover hydrated LiCl from multicomponent salt mixtures via a hydration‐assisted O···Li+ binding mode, enabling scalable lithium separation with Li/Na, Li/K, and ...
