σ‑Hole Engineering Enables Selective Supramolecular Isomer Formation in Sb(III) Hosts
Pnictogen bonding (PnB) has emerged as a directional and tunable noncovalent interaction, yet the presence of multiple σ-holes on trivalent pnictogen centers introduces a question: can individual σ-holes be selectively addressed for binding, and do their relative reactivities remain unchanged upon sequential binding? T...
