Monosubstituted ferrocene derivatives, [4-ω-[4-(4-methoxyphenoxycarbonyl)phenoxycarbonyl] alkoxycarbonyl] phenyl]ferrocene (MAPF-n)(n is the number of carbon atoms in the methylene chain, n = 1〜7, 10 and 11) have been synthesized in our laboratory. The liquid crystallinity of these compounds was investigated by dufferential scanning calorimetry and polarizing microscopy observations. The result suggested that four kinds of MAPF-n (n = 4, 6, 10 and 11) exhibit liquid crystallinity. In this study, dielectric measurements were carried out in order to discuss molecular motions. These compounds showed two clearly separated relaxation processes above glass transition. Phenomenological analyses of these relaxation were made to establish activation energies of relaxation processes and parameters characterizing the broadness of the relaxation time distribution.
