1,1?-Disubstituted Ferrocene-Containing Thermotropic Liquid Crystals of structure [Fe{(?5-C5H4)COOC6H4XC6H4OCnH2n+1}2] (X ? OOC or COO). Influence of the orientation of the central ester function on the mesogenic properties

The two series I and II of 1,1′ -disubstituted ferrocenes which differ by the direction of the esterfunction included in the rigid organic part were synthesized and their liquidcrystalproperties examined. These latter were found to be strongly dependent on the orientation of the connecting ester group and on the alkyl chain length.

The synthesis and mesomorphic properties of the title compounds, prepared by free-radical polymerization (or copolymerization) of a ferrocene-containing methacrylate monomer (with methylmethacrylate), are reported.
