Two liquid-crystalline compounds having perfluoroalkyl-terminated mesogens at both ends of poly-(ethylene oxide) chains have been prepared These compounds show smectic A (SA) and C phases over 100°C. The SA-Iso (isotropic) transition temperatures are higher by about 70°C than those of the two corresponding alkyl-substituted compounds The incorporation of lithium triflate into the perfluoroalkyl-terminated mesogen-containing compounds widens the temperature ranges of the SA phases for the resulting complexes. The complexes of these compounds containing 50 mol-% of lithium triflate exhibit columnar phases. The ionic conductivities of the homotropically aligned complexes based on fluoroalkyl-terminated compounds along the direction perpendicular to the mol. director of the SA phases are higher than those of the corresponding compound containing alkyl groups. The increase of the ionic conductivities as well as the stabilization of the smectic phases for these perfluoroalkyl-terminated compounds may be due to the formation of more stabilized layered structures through the intermol. interactions among the perfluoroalkyl moieties.
