新设计的偶氮苯衍生物的光异构化可逆地改变其在溶液中的自组装，分别形成扭曲的超分子纳米纤维和无定形聚集体。当用可听声照射样品溶液时，前一个组件由于其流体动力学取向而表现出LD响应，但后一个组件在声诱导的流体流动中是LD沉默的。
Photoisomerizations of a newly designed azobenzene derivative reversibly change its self-assembly in a solution to form twisted supramolecular nanofibers and amorphous aggregates, respectively. When irradiating the sample solution with audible sound, the former assembly exhibits a LD response due to its hydrodynamic orientation, but the latter one is LD silent, in the sound-induced fluid flows.
