Abstract

Abstract Chiral ligands are introduced whose conformations may be regulated by the presence of Ca2+ ions. These compounds are assembled from two types of C3-symmetric molecules as anchors (type 1 and type 2) and extended by chiral peptide residues. Their ion- binding properties are examined by a combination of experimental and theoretical tools (empirical force field (EFF) calculations). The calculations provide a conceptual framework ...
