| Outline of Final Research Achievements |
(1)A novel polymer consisting of helical peptide and phenyleneethynylene moiety was synthesized by the self Sonogashira coupling polymerization of a telechelic helical peptide. The peptide with modified terminal groups exhibited Cotton effects higher than those of the precursor, presumably due to the participation of the terminal amide groups into the intramolecular hydrogen bonding strands as well as increase of rigidity due to the formation of conjugated phenyleneethynylene moieties, resulting in the stabilization of the helical structure.
(2)Telechelic helical poly(phenyleneethynylene)s bearing end iodo and ethynyl groups were successfully synthesized by the Sonogashira coupling reaction of the prepolymer with N-Boc-3,5-diiodo-4-hydroxy-D-phenylglycine hexylamide and p-diethynylbenzene, respectively. The formed polymer was treated by Sonogashira coupling polymerization with 1,6-diethynylpyrene and 4,4-diethynylbiphenyl to obtain the corresponding polymers.
