Abstract

Self-assembled periodic micro-nanostructures triggered by responses to external influences often occur in anisotropic self-assembled supramolecular soft-matter systems (such as liquid crystal (LC) systems). However, these structures are often not easily to control or even change, e.g., orderliness of the structures. A pre-built 1D periodic microgroove structure on the planar cholesteric LC cell is used to study whether it can effectively improve the large-area order of the electro-induced 2D deformation structure. Experimental results show that the 2D microgrid structure caused by the Helfrich deformation of the CLC can be effectively controlled to be ordered macroscopically by the pre-built 1D periodic microgroove structure. Furthermore, the uniformity of the microgrid size is also improved. The findings enhance the potential applicability of the well-known Helfrich deformation phenomenon and provide an example for further control of periodic micro-nanostructures in self-assembled supramolecular systems.
