Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

open access: yesAdvanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.
