We have designed and synthesized liquid-crystalline twin oligomers containing mesogenic groups at the both ends of ethylene oxide chains. Thermally stabilized smectic A phases have been induced by the complexation with LiCF_3SO_3. This behavior is due to the ion-dipole interaction between the ethylene oxide moiety and the lithium ion. Ionic conductivity has been measured by using the custom-designed cell built with a pair of parallel glass substrates and stainless electrodes. The formation of the monodomain of homeotropic molecular orientation was confirmed by conoscope observation. The results of ionic conductivity measurements suggest that two-dimensional ionic conductivity has been obtained in the homeotropically oriented ethylene oxide layer of the liquid-crystalline monodomain.
