Photoresponsive chiral molecular crystal for light-directing nanostructures

摘要: A photoresponsive chiral molecular crystal (abbreviated as PCMC) was programmed and synthesizied by localizing a isosorbide at the core between two amphiphilic azobenzene building blocks. Owing to bent-shaped geometry, PCMC can self-organize into helical nanoribbons with highly ordered smectic domain. Since has not only an intrinsic chirality but also function, single handedness were transformed flat nanobelts irradiation ultraviolet light. Additionally, its chiroptical properties fully recovered initial state upon exposure visible Fine tuning nanoarchitectures using remote controllable feature of presented in this work lead design novel functional materials that are potentially applicable optical sensors biomimetic devices.
