Abstract

The n-alkyl derivatives C₁₆H₃₃OH, C₁₆H₃₃OCH₃, C₁₆H₃₃OC₆H₅, C₁₂H₂₅OC₆H₅, (C₁₂H₂₅O)₂C₆H₄ or (C₁₆H₃₃O)₂C=O have been incorporated into the n-alkyl side chain layers formed by the amphiphilic polymer C₁₆O₅ and its smectic equimolar complex with LiClO₄. All systems have conductivities ∼ 10^-2 S cm^-1 at 100°C but the systems with n-alkyls have higher conductivities at lower temperatures (∼10^-4 S cm^-1 at 40°C) which are more than two orders of magnitude greater than those of C16O5:LiClO₄. This is attributed to the increase in internal space of the ionophilic helical layers brought about by the expanded ionophobic layer.
