We propose a strategy to endow a helical polymer chain with dynamic spring-like motion through the one-dimensional self-assembly of peripheral amphiphilic molecules. In our system, we employed a semi-artificial helical polysaccharide presenting peripheral amphiphilic chlorophyll units as a power device that undergoes contractive motion in aqueous media, driven by strong II-II interactions of its chlorophyll units or by cooperative molecular recognition of bipyridyl-type ligands through pairs of chlorophyll units, thereby converting molecular information into the regulated motion of a spring.

我们提出了一种策略，赋予螺旋聚合物链的动态弹簧般的运动，通过一维自组装的周边两亲分子。在我们的系统中，我们采用了一个半人工螺旋多糖呈现周边两亲性叶绿素单位作为动力装置，经历收缩运动在水性介质中，由其叶绿素单位的强II-II相互作用或通过对叶绿素单位的联吡啶型配体的合作分子识别驱动，从而将分子信息转化为弹簧的调节运动。
