PBa17 光反応性高分子液晶の直線偏光光反応による液晶の配向制御

抄録

We describe the synthesis of a new photoreactive polymer liquid crystal (PLC) and the photoalignment control of liquid crystal on PLC films by linearly polarized (LP) UV light irradiation. The irradiated PLC film showed negative dichroism and the homogeneous LC alignment can be achieved on the irradiated PLC film. The alignment direction was perpendicular to the E of the LP-UV light, and was changed parallel to E when the irradiation time was long.
