dc.description.abstractPhoto-crosslinkable polyimide(PI) which contains CF(3) moiety was synthesized. Polarized UV light transformed ketone group of PI to hydroxyl group, which was confirmed by IR and UV-visible spectroscopy. We investigated the dichroic UV-absorption before and after photo-reaction with linearly polarized light. The grooves were formed on the surface of PI film after irradiation with polarized UV-light. It was interesting to observe that the alignment of grooves was perpendicular to the polarized director, while the orientation of LC was parallel to the groove alignment.-
