An unprecedentedly high degree of chiral amplification of supramolecular helices in a sergeants and soldiers system was realized using a propeller-shaped molecule, triphenylamine (TPA), as the monomer. One sergeant controlled the handedness of 500 soldiers in supramolecular helices. We further demonstrated that a TPA derivative could switch its role from sergeant to soldier and depending on its partners. These achievements could be realized using the dynamic propeller conformation of TPA and provide new insights into supramolecular assemblies and the supramolecular chiral amplification of helices.
使用螺旋桨状分子三苯胺（TPA）作为单体，在“军士与士兵”体系中实现了超分子螺旋前所未有的高度手性放大。一名“军士”控制着超分子螺旋中500个“士兵”的手性。我们进一步证明，一种TPA衍生物可以根据其伙伴从“军士”转变为“士兵”。利用TPA的动态螺旋桨构象可以实现这些成果，并为超分子组装和螺旋的超分子手性放大提供新的见解。
