Recently, smectic liquid crystals (SLCs) have been suggested as a new class of soft superstructure materials. Thanks to the responsiveness to various external stimuli and rich self-assembled hierarchical superstructures, SLCs have shown a broad application prospect in the fields of optoelectronic device, micro-nano machining, surface chemistry, etc. However, dynamic manipulation of smectic hierarchical superstructures is still challenging. Related controlling mechanism is unclear, controllable parameter is monotonous and the modulation efficiency is low, which are not studied thoroughly and greatly restrict the application process. This project focuses on precise construction and dynamic manipulation of SLC hierarchical superstructures, revealing the inherent controlling mechanism and rules on the molecular scale, developing a new method for efficiently tuning smectic superstructures and further exploring their functionalities and applications. The main contents are as follows: (1) electric-field driven focal conical superstructure and its microlensing effect; (2) efficiently tuning hierarchical superstructures by electric/optical combining stimuli and elucidating relevant mechanism and rules; (3) light-activated chiral oil streak superstructure and its particle assembly function. With this project, new methods, rules and effects will be explored in the stimuli/LC interaction, the manipulation capability of hierarchical superstructures will be greatly enhanced, and more innovated high-performance optoelectronic functional materials, devices and applications will be stimulated and developed.
