Abstract

We previously reported supramolecular polymers formed by π-π stacking between disc-shaped hexamers (rosettes) of barbituric acid-functionalized π-conjugated molecules. Herein, we investigated the impact of amide-mediated hydrogen bonding along two types of polymer backbones formed by distinct stacking of rosettes. The stabilization of the hydrogen bonds strongly depends on the intrinsic stacking arrangement of rosettes, which competes with the amide hydrogen-bonding.

超分子圆盘的空间位阻与氢键的竞争与合作。

我们以前报道过由巴比妥酸功能化π共轭分子的圆盘形六聚体（玫瑰簇）之间π-π堆叠形成的超分子聚合物。在这里，我们研究了酰胺介导的氢键沿两种类型的聚合物骨架的影响，这些聚合物骨架是由不同的花环堆叠形成的。氢键的稳定性很大程度上取决于玫瑰花的内在堆叠排列，这与酰胺的氢键形成竞争。
