| Outline of Final Research Achievements |
Optically-electrical-magnetic active functional polymers were synthesized using biological liquid crystal, bio-active materials, and synthetic liquid crystals. Especially, lyotropic liquid crystallinity of fd phage with linear shaped form as a reaction field was confirmed. The phage shows smectic liquid crystal with layer structure and cholesteric liquid crystal with structural chirality. Synthesis of conducting polymer was carried out in the phage as liquid crystal reaction field. Next, polymerizations were carried out in hydroxypropyl cellulose having lyotropic liquid crystallinity. Further, a polymer having stable radical group was synthesized in liquid crystal to yield chiral paramagnetic polymer.
