[28]Hexaphyrin derivatives for anion recognition in organic and aqueous media. Issue 10 (4th January 2016) - Figueira, Flávio
Abstract : Hexaphyrin-based anion chemosensors are reported for the first time. Abstract : Hexaphyrin-based anion chemosensors are reported for the first time. The meso-hexakis(ethylenediamine)-substituted [28]hexaphyrins2 and3 revealed strong affinity for F −, AcO − and H2 PO4 − . Adsorption constants in aqueous media were determined on a gold piezoelectric crystal coated with2 and3 . 1 H NMR titrations and molecular dynamics simulations showed the main interactions between hosts and guests.
