The two homologous series of monosubustituted(HPF-n, n is the number of carbon atoms in the alkyl group) and disubstituted ferrocene derivatives(bHPF n), which are shown in Figure 1, have been prepared. The phase transition of these compounds has been studied by the differential scanning calorimeter(DSC) and the polarizing microscope. All of the HPF-n have exhibited no liquid crystal phase. On the other hand, all of the bHPF-n have displayed the liquid crystal phase. These liquid crystal phases were identified to be a smectic C phase. This suggests that the S-conformation of ferrocenyl compounds may be favoured for an interdigitated layer packing arrangement. On the heating process, all of the ferrocene derivatives have exhibited crystal-crystal phase transitions.
