We report a precise control over the hierarchy levels in the outstanding self-organization process shown by chiral azobenzene dimer 1. This compound forms uniform toroidal nanostructures that can hierarchically organize into chiral nanotubes under the control by temperature, concentration, or light. The nanotubes further organized into supercoiled fibrils, which finally intertwined to form double helices with one-handed helical sense.
我们报告了在手性偶氮苯二聚体 1 所表现出的出色自组织过程中对层次结构的精确控制。该化合物形成均匀的环形纳米结构，在温度、浓度或光照的控制下可以进一步有序排列成手性纳米管。纳米管进一步组装成超螺旋状的原纤维，最终相互交织形成具有单螺旋手性的双链螺旋。
