Natural systems transfer chiral information across multiple length scales through dynamic supramolecular interaction to accomplish various functions. Inspired by nature, many exquisite artificial have been developed, in which controlling the chirality holds key completing specific tasks. However, achieve precise and non-invasive control modulation of these remains challenging. As a stimulus, light can be used remotely with high spatiotemporal precision. In contrast common molecular switches, synthetic motor act as multistate chiroptical switch unidirectional rotation, offering major potential regulate more complex Here, we present light-driven motor-based polymer, intrinsic is transferred nanofibers, rotation motors governs morphology polymer. The resulting polymer also exhibits light-controlled aggregation-induced emission. These findings photochemically tunable system water pave way for developing motor-driven materials.
