Abstract
Linearly polarized (LP)-ultraviolet (UV) photoreaction of side-chain liquid crystalline polymer of poly[6-(4′-cinnamoylbiphenyl-4-yloxy)hexyl methacrylate] (SLCP 1) and low-molecular-weight (LMW)-LC alignment behavior on photoreacted SLCP 1 film were studied. LP-UV photoreacted film showed large negative dichroism and aligned LMW-LC with the direction perpendicular to the direction of electric vector (E) of incident LP-UV light. It was clarified that the unphotoreacted and non-aggregated mesogenic group played an important role to control the direction of LMW-LC alignment.
