Paper Abstract

3,4-Dialkoxybenzoates of pentaerythritol and structural related polyhydroxy compounds have been synthesized and investigated by polarizing microscopy, differential scanning calorimetry and some of them also by x-ray scattering. Despite the fact that these compounds are neither anisometric nor amphilphilic in a classical sense they can display columnar liquid-crystalline phases. It is proposed, that the segregation of the polar regions and the lipophilic alkyl chains into separate regions is mainly responsible for the formation of these mesophases.
