Poly(p-phenylenevinylene) (PPV) derivatives with an optically active group in the side chain were prepared to investigate their mesomorphic, electrical and optical properties. The polymer containing the 2-methylbutoxy moiety in the side chain showed a cholesteric liquid crystalline phase. In the polymers containing optically active and mesogenic moieties, absorption maxima and emission maxima were shifted to shorter wavelength, and stronger circular dichroisms(CDs) were observed compared to the polymers containing mesogenic moieties. In the case of polymers containing optically active and mesogenic moieties, oxidation and reduction peak potentials had higher values compared to the polymers containing mesogenic moieties.
