PBa02 フェロセンを含む液晶性物質の合成と物性(XVIII) : [4-[ω-(cholesteryloxycarbonyl)nonyloxycarbonyl]phenyl]ferroceneの動的粘弾性に関する研究

抄録

A series of monosubstituted ferrocene derivatives, [4-[ω-(cholesteryloxycarbonyl) alkoxycarbonyl]phenyllferrocene (abbreviated hereafter CAPF-n, where n is the carbon number of the flexible methylene chain), have been synthesized. Phase trasition phenomena of these compounds have been studied by differential scanning calorimeter, polarizing microscope, and so on. In this study, the dynamic viscoelasticity of CAPF-9 was measured as a function of temperature. In the heating process, an abrupt drop of the storage modulus of clasticity (G') was not observed around the clearing temperature. In the liquid state, G' decreased gradually with increasing temperature. Such behavior is different from the feature of the other low molecular weigh liquid crystals.
