A Designed Cavity for Zwitterionic Species: Selective Recognition of Taurine in Aqueous Media
Résumé
The perfect host: Hemicryptophane 1 selectively binds taurine neurotransmitters in CD3CN/D2O. Association constants determined by DOSY NMR spectroscopy demonstrate that this recognition is highly selective over other related substrates. DFT calculations emphasize that only weak intermolecular interactions stabilize the host–guest association (see figure).
