abstract Hexaphyrin-based anion chemosensors are reported for the first time. The meso-hexakis(ethylenediamine)-substituted [28]hexaphyrins 2 and 3 revealed strong affinity for F-, AcO- and H2PO4-. Adsorption constants in aqueous media were determined on a gold piezoelectric crystal coated with 2 and 3. H-1 NMR titrations and molecular dynamics simulations showed the main interactions between hosts and guests.
