Abstract

Novel glycosides synthesized by linking D-glucose to three different non-polar aglycones, cinnamyl alcohol, chloroxylenol and 3-pentadecylphenol showed both thermotropic and lyotropic liquid crystal phases. The effect of inclusion of a rigid spacer in between hydrophilic and hydrophobic parts on the stability of liquid crystal phases is investigated. Both acetylated and deacetylated compounds exhibited thermotropic and lyotropic liquid crystal behaviour. The liquid crystal phases were confirmed as smectic A, smectic B and hexagonal columnar by X-ray studies.

Keywords: Glycolipids, liquid crystal, lyotropic, thermotropic.
