Outline of Final Research Achievements

We investigated molecular reorientation behavior of liquid-crystalline composite film incorporated photo-alignable liquid cystalline polymer film with hydrogen bonding unit (H-PLCP), that can control its molecular alignment upon exposure to linearly polarized ultraviolet light and various functional materials containing hydrogen bonding accepter. We tried to fabricate facile functional materials exploiting dynamical change in hydrogen bond between H-PLCP substrate and the functional materials and succeeded in controlling thermal and optical property of the complex by adjusting the composition of the film. We also explored molecular reorientation behavior and application of novel photo-alignable liquid-crystalline polymer film composed of N-benzylideneaniline derivatives at side chain.
