Abstract
Binding straps: Chiral calix[4]pyrroles 1 bearing an (R)- or (S)-binol-derived strap on one side of the tetrapyrrolic core (see picture) were synthesized and characterized. The resulting systems bind selected chiral carboxylate anions (shown in red) with high affinity in acetonitrile while at the same time exhibiting enantiomeric discrimination.
