We demonstrate a controlled chiral supramolecular assembly of achiral porphyrins induced by chiral d- and l-arginine (Arg) in water. Induction of chirality was confirmed by circular dichroism. TEM and SEM images confirm that these twisted ribbons are indeed formed by right- and left-handed helices with d- and l-Arg in water, respectively. The chiral assembly pathways described here are hierarchical, opening up the possibility that simple changes on microscopic (nm) length scales can be used to control structures on macroscopic (mm) length scales.
我们展示了在水中由手性d-和l-精氨酸（Arg）诱导的非手性卟啉的可控手性超分子组装。通过圆二色性证实了手性的诱导。透射电子显微镜（TEM）和扫描电子显微镜（SEM）图像证实，这些扭曲的条带确实分别由水中d-和l-精氨酸形成的右手和左手螺旋构成。这里描述的手性组装途径是分层的，这为利用微观（纳米）长度尺度上的简单变化来控制宏观（毫米）长度尺度上的结构提供了可能性。
