摘　　要：我们曾研究了以季铵盐作为相转移催化剂，通过二茂铁的芳基化反应，合成了一系列带活泼官能团的二茂铁衍生物［１］。这些衍生物可作为合成二茂铁非线性光学材料、液晶材料的良好中间体［２－４］。为了探索分子几何结构与介晶性能之间的关系和制备结构新颖、稳定性能好、...Through the arylation of ferrocene the m nitrobenenylferrocene m Fe C 6H 4 NO 2 was prepared which was reduced by Sn to 3 ferrocenylaniline m Fe C 6H 4NH 2.Seven new complexes 1～7(Fe-C 6H 4-N=CH-C 6H 4O C nH 2n+1 ,n=4,6,8,10,12,14,16) were prepared by the condensation of ferrocenylaniline with corresponding p alkyloxybenzaldehyde (C nH 2n+1 O-C 6H 4-CHO).The structures of the complexes were characterized by IR, 1H NMR and elemental analysis.The study of DSC and optical microscopy shows that the complexes have high thermal stability and appear mesogenic properies in 50～120℃.The transition temperature of complexes more depends on the molecular geometrical shape(meta substituted) than on the chain length(n).
