所合成化合物的结构由红外光谱分析(IR)和核磁共振(

H NMR)测试确定。示差扫描量热(DSC)测试及偏光显微镜(POM)观察显示

产物ZO2未表现出液晶性

ZO3显双向液晶性

呈近晶相;ZO4、ZO5、ZO6呈单向液晶性

为向列相。它们的织构随

ZO6的偏光织构最完善。

Abstract

Azobenzene and its derivatives are widely used mesogenic groups. In this paper

1-bromo-

-(4-methoxyazobenzene-4'-oxy)alkanes(ZO

) have been synthesized in which the number of methylene unit varies from 2 to 6. The structures of the synthesized compounds were confirmed by IR and

H NMR spectroscopy. The differential scanning calorimetry (DSC) measurement and polarizing optical macroscope (POM) observation showed that the resulting compounds exhibited thermotropic liquid crystalline mesomophism except for ZO2. ZO3 displayed semectic phase

and ZO4

ZO5 and ZO6 showed nematic phase. The texts pattern became more perfect with the increase of methylene number.
