摘要
The effect of hydroxyl group on the secondary structure of serine-based helical polyacetylenes was investigated. The structures of the polymers were examined by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy. It was found that derivating from the two conformers, the distance between the pendent groups becomes longer. It was confirmed that the hydroxyl groups greatly affect the secondary structures of the polymers, which was supported by liquid-state IR and molecular modeling studies.
