| Outline of Final Research Achievements |
A selective introduction of photosensitivity to the polymeric film by adjusting the H-bond and in-situ reaction such as condensation at the free surface attained a precise photoinduced orientation (photoalignment) of the film. Especially, we have successfully investigated the formation of photoreactive Schiff base using a polymeric film containing phenyl aldehyde side groups coating of a amine derivatives, which showed the photoinduced orientation, and introduction of the H-bond between a benzoic acid derivatives and Schiff base and/or cinnamic acid derivatives which showed selective photoalignment and introduction of the photoinactivity of the aligned film.
