| Outline of Final Research Achievements |
A novel poly(biphenylylenediethynylene) derivative consisting of crown ether strapped 3,3'-biphenylylene bearing triethylene glycol-derived pendants and diethynylene units (poly-1) was synthesized. Poly-1 complexed with L-Ala folded into a preferred-handed helical conformation in tetrachloroethane(TCE)－acetonitrile (MeCN) mixed solvents (MeCN > 80vol%), showing an intense induced circular dichroism in the absorption region of its main chain. We found that the induced preferred-handed helical conformation in poly-1 was maintained very stably even after complete removal of L-Ala in TCE－MeCN mixed solvents (MeCN > 80vol%), while it was instantly transformed into a random conformation in TCE. It was found that fullerene was encapsulated in the inner cavity of the helical poly-1.
