Theoretical study of the helical conformers and ECD spectra of 8-aminoquinoline polymers

Based on the molecular force field, the stable conformers of 8-aminoquinoline oligoamides containing chiral β-pinene have been searched. The stability of helical conformers is different when β-pinene connects with 8-aminoquinoline at the nitrogen terminal and carbon terminals. And β-pinene can form delocalized π-bonds at the C-terminal of oligoamides, which can improve the strength of absorption spectra of the CQn.
