The synthesis and mesomorphic properties of the first family of unsymmetrically-1,3-disubstituted ferrocene-containing thermotropic liquid crystals are presented. The title compounds exhibited enantiotropic liquid crystalline phases (nematic and/or smectic A and smectic C phases) associated with large anisotropic domains.
