报道了两个系列二茂铁衍生物,FcC_6H_4N=CHC_6H_4OC_nH_(2n+1)(系列I) 和FcC_6H_4N=CHC_6H_4O_2CC_6H_4OC_nH_(2n+1)(系列II)(Fc:ferrocenyl;n = 2,4,6,8,10,12,14,16),并通过DSC和热台偏光显微镜对其介晶性进行 了研究。系列I不具有介晶性,系列II呈较窄的液晶温度范围。其结果显示分子的 刚性部分长度对介晶性有重要影响。

Two series of ferrocene compounds with structure of Fc-C_6H_4-N=CH- C_6H_4-OC_nH_(2n+1) (series I) and Fc-C_6H_4-N=CH-C_6H_4-O_2C-C_6H_4- OC_nH_(2n+1) (series II) (Fc:ferrocenyl; n = 2, 4, 6, 8, 10, 12, 14, 16) were prepared. Their mesogenic behaviors were studied with DSC and polarized optical microscopy. The results show that series I compounds do not possess liquid crystalline properties, while series II compounds have narrow liquid crystal temperature range. These results prove that the length of the rigid core in the molecule has an important effect on the mesogenic properties.
