Macroscopic and precise alignment control of functional molecules represented by liquid crystals (LCs) and polymers is the key to generating a new function and enhancing their performances. Among various alignment techniques, a photoalignment method offers the greatest potential to finely control molecular alignment because of the capability of micro- to nano-patterning with remote processes. Recently, we have proposed a novel photoalignment method based on a new concept of scanning wave photopolymerization (SWaP). This method utilizes molecular diffusion triggered by the localized photopolymerization, enabling to generate an arbitrary alignment patterns merely by single-step photo-irradiation. In this study, we fabricated liquid-crystalline polymer networks directed by SWaP.
