Abstract

An oligopyridine foldamer, whose structure is dictated by bifurcated hydrogen bonds, was designed to recognize the surface of calcite through three carboxylates, projected from one face of the molecule. At low concentrations of the trimer, elongated calcite crystals with angular, teeth-like growths, identified as {↑0l} faces, were exclusively formed. In the presence of a related monomer, only calcite rhombohedra are formed, indicating that it is the ordered array of carboxylates that causes the morphological changes, via a specific interaction between the foldamer and the newly expressed faces of the growing calcite crystals.
