Abstract
In the smectic phase of dimers with a bent conformation; n(O)AM5AM(O)n(n=12,14,16), we studied texture of the mesophase using a polarizing microscope, and measured switching currents and optical birefringences. Consequently we confirmed that all the compounds show antfferroelectric phases. Based on these results, the layer structures were determined, and it was found that the structure of 12AM5AM12 is different from 140OAM5AMO14.
