以 4,4′- ( α,ω-癸二酰氧 )二苯甲酰氯 ,2 ,4-二羟基 - 4′-烷氧基偶氮苯为单体 ,通过溶液缩聚反应 ,合成了一类新的含 T-型二维液晶基元的液晶高分子配体 ,它们的液晶行为用 DSC、偏光显微镜和 X射线衍射进行了表征。发现高分子配体均为向列型热致液晶高分子 ,液晶态温度范围较宽。液晶高分子配体的熔点 ( Tm)和液晶态的清亮点( Ti)随分子中末端烷氧基增大呈规律性变化。 A series of compounds were synthesized by solution polycondensation reaction using 4,4’- (α, ω-decanedioxy) dibenzoyl chloride and 2,4-dihydroxy-4’-alkyloxyazobenzene as monomers The new liquid crystal polymer ligands containing T-type two-dimensional liquid crystal motifs, whose liquid crystal behavior was characterized by DSC, polarized light microscopy and X-ray diffraction. It is found that the polymer ligands are nematic thermotropic liquid crystal polymers, the liquid crystal temperature range is wide. The melting point (Tm) and the clearing point (Ti) of the liquid crystal polymer ligand change regularly with the increase of the terminal alkoxy groups in the molecule.
