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
一种低聚吡啶折叠体,其结构由分叉的氢键决定,旨在通过三个羧酸盐识别方解石的表面,从分子的一个表面突出。在三聚体的低浓度下,专门形成具有角状齿状生长的细长方解石晶体,确定为 0l} 面。在相关单体的存在下,仅形成方解石菱面体,这表明通过折叠体和生长方解石晶体的新表达面之间的特定相互作用,是有序排列的羧酸盐引起了形态变化。
