| Outline of Final Research Achievements |
VCD measurements were performed on L-polylactic acid of various molecular weights. In addition, dimers, tetramers, hexamers were synthesized using L-lactic acid as a starting material. VCD measurement and theoretical calculations of synthesized oligomers were carried out. Furthermore, synthesis of corresponding polyamide oligomers and hybrid oligomers was carried out. ECD and VCD of the synthesized hexamers were measured. IR and VCD spectra of their ester carbonyl, amides I and II were observed, and the three-dimensional structures were analyzed from these spectra. In addition, considering the azide, nitrile, isocyanide groups, and alkyne as a candidate functional group to replace the carbonyl group, model compounds containing these functional groups were synthesized and the possibility of each functional group was investigated.
