Large area ordered structure by organic molecular soft building blocks is one of the most exciting interdisciplinary research areas in current materials science and nanotechnology. Directed self-assembly of soft condensed matter such as block copolymers, supramolecules, surfactants, colloids, and liquid crystals (LCs) have been massively studied to get very periodic and defect free structures for the potential application of micro-fabrication. Here, the origin and the behavior of LC defect structures are described based on liquid crystal physics and brand new defect structures of smectic LC are introduced for the first time in LC research field and are described by theoretical approach. The present findings at here pose new theoretical challenges and potentially open the way for lithographic applications based on liquid crystalline materials. As potential applications, the highly ordered LC defect arrays can be used for various lithographic templates, photolithographic mask, optical component arrays and superyhydrophobic surfaces. |
