PBb04 斜め非偏光露光による低分子液晶の光配向制御

抄録

We investigated photo-alignment control of liquid crystals on photo-crosslinkable polymer films comprising 2-cinnamoyloxyalkyloxybiphenyl mesogenic side-group. Their films showed optical anisotropy by the slantwise irradiation of non-polarized UV light and the tilted alignment of liquid crystals can be achieved on their irradiated films. In addition the tilt angle can be controlled by the controlling amount of irradiation and the incident angle of irradiation.
