A series of ferrocene-based rod-like mesogens has been synthesized in which the oxadiazole unit is in a terminal position. The length of the terminal S-alkyl chain, alkyl spacer length, and substitution on lateral position have been varied. All the synthesized compounds are thermally stable and exhibit mesomorphism. Most of them display two enantiotropic mesophases nematic-smectic C. Only one compound exhibits enantiotropic smectic C phase.
