The monosubstituted ferrocene derivatives, -[4-(4-methoxyphenoxycarbonyl) phenoxy]alkoxycarbonyl ferrocene, were synthesized in order to compare the liquid crystallinity to that of disubstituted ferrocene derivatives, 1,1'-bis[-[4-(4-methoxy-phenoxycarbonyl)phenoxy]alkoxycarbonyl]ferrocene. Some of the monosubstituted ferrocene derivatives containing relatively longer flexible spacer showed the liquid crystalline phase, nematic and/or smectic phases. The crystal structure of 2-[4-(4-methoxyphenoxycarbonyl)phenoxy] ethoxycarbonyl ferrocene was determined by X-ray diffraction method using a single crystal. The molecular structure revealed a bent structure that is almost a half of "Z" shaped molecular structure of 1,1'-bis[2-[4-(4- methoxyphenoxycarbonyl)phenoxy]ethoxycarbonyl]ferrocene.
Synthesis and physical properties of ferrocene derivatives (XXV) liquid crystallinity of 1,3-disubstituted ferrocene derivatives

, p. 150 - 159 (2012/01/03)
Liquid crystallinity of 1,3-disubstituted ferrocene derivatives was studied by DSC and polarizing microscope. The name of the derivatives is 1,3-bis[-[4-(4-methoxyphenoxycarbonyl)phenoxy]alkyloxycarbonyl]ferrocene. Nine members from n = 2 to 10 were synthesized (n is carbon number of alkyl chain in the sample). All samples except n = 2 and 4 exhibited monotropic nematic liquid crystalline phase. In addition, smectic X (not yet completely identified) was also observed in n = 8 and 10. Liquid crystalline phase transition phenomena were discussed from a viewpoint of molecular shape.
