Abstract

Some new liquid crystalline allene derivatives incorporating a heterocyclic 1,3,4-thiadiazole ring as a constituent of the rigid core have been synthesized both as racemats and in enantiometrically enriched forms. The compounds were investigated by polarizing microscopy and by differential scanning calorimetry. The three ring compounds exhibit broad regions of smectic C-phases. Most of the optically active compounds show broad Sc^*-phases with moderate values of the spontaneous polarization.
