| Outline of Final Research Achievements |
There has been an increase in research on applications of microphase separated (MPS) structure in block copolymer films to nanotemplate and nanopatterning materials. We have reported a photoalignment method for the MPS structure in liquid crystalline (LC) azobenzene block copolymer thin film with a polarized light irradiation. In this project, we have implemented the elucidation for the photoalignment mechanisms of the MPS structure in the LC block copolymer films and the application of the photoalignment method to molecular devices. We conducted 1) realtime observations for the molecular hierarchic structures in the photoalignment MPS system, 2) formation of a nano-relief surface via a supramolecular LC block copolymer films with detachable mesogens, 3) orientational control of MPS structure from a free surface with surface segregation. The proposals can be the breakthrough of the precise mechanism and new material strategies for the LC block copolymer photoalignment systems.
