Control of molecular alignment of liquid crystals is key to the development of highly functionalized photonic, electronic, and mechanical materials and devices. Of various alignment techniques, a photoalignment method has drawn much attention. However, the fine control of microscopic three-dimensional molecular alignment remains a challenge in this method. To overcome the issue, we have proposed a novel method based on a concept of molecular diffusion termed scanning wave photopolymerization. In this study, we fabricated the liquid-crystalline polymer films with three-dimensionally aligned molecules with layer structures by finely tuning polymerization conditions.
