AIM-12S and AIM-12R engage in host–guest recognition with β-CD to yield multifunctional chiral supramolecular assemblies (AIM-12S/R@β-CD) of distinct morphologies: rod-like needles (AIM-12S@β-CD) and thin films (AIM-12R@β-CD). These architectural divergences translate into strikingly different deposition behaviors on rice leaves, as indicated by their contact angles (116° for AIM-12S@β-CD versus 49° for AIM-12R@β-CD). Owing to its stronger deposition, AIM-12R@β-CD penetrates and disrupts bacterial biofilms more efficiently, thereby eradicating resident bacteria and achieving superior suppression of bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo). Furthermore, earthworm safety assays confirm that AIM-12R@β-CD exhibits favorable environmental compatibility. Live and dead bacterial cells are visualized as green and grey signals, respectively.
