摘　　要：通过相转移催化剂作用下的二茂铁芳基化反应，合成了ｐ－硝基苯基二茂铁（Ⅰ）。用Ｓｎ还原Ⅰ得到４－二茂铁基苯胺（Ⅱ），Ⅱ与ｐ－烷氧基苯甲醛缩合，合成了二茂铁Ｓｃｈｉｆ碱型配合物Ⅲ１～Ⅲ７。配合物结构经ＩＲ，１ＨＮＭＲ和元素分析确证。ＤＳＣ和偏光显微镜研究结果显示，该类配合物具有较好的稳定性，并在较低的温度出现介晶相。相转变温度随末端Ｃ原子数的增加而呈稳定下降趋势。Through the arylation of ferrocene was offen the p nitrobenene ferrocenee(Ⅰ) was reduced by Sn to get 4 ferrocenylaniline(Ⅱ). Seven new complexes Ⅲ 1～Ⅲ 7 (Fc C 6H 4 N=CH C 6H 4OC nH 2n+1 ,n=4,6,8,10,12,14,16) were prepared by the condensation of Ⅱ with corresponding p alkyloxybenzaldehyde (C nH 2n+1 O C 6H 4 CHO). The structure of the complexes was characterized by IR, 1H NMR and elemental analysis. The study of DSC and optical microscopy shows that the complexes have high stability and appear mesogenic properies in low temperature. The transition temperature steadly lowers as the number(n) of carbon increases.
