P-54: A Study on the Photo-Alignment of the Polymer-Containing Cinnamate Group Using a New Single UV-Exposure Method

摘要

To solve the problems of conventional rubbing methods, we synthesized a suitable polymer having photo-reactive cinnamate groups as UV-alignment material. Using this polymer we developed new photo-alignment methods, which can control the liquid crystals to polar and azimuthal direction in polymer-alignment layer by single UV-exposure. In this paper, we also investigate the LC-alignment mechanism by UV light with experimental data.
