摘要
以 4 -(4′-烷氧基苯甲酰氧基 )苯甲酸作为液晶中间体 ,合成了在分子中部含齐聚氧化乙烯的系列酯 -醚液晶化合物 .对其化学结构和液晶性能进行了表征 ,除个别化合物外 ,其余样品均具有热致液晶性 .
A new series of ester ether liquid crystal compounds with oligo(oxyethylene) middle units has been synthesized by using 4 (4′ alkoxybenzoyloxy)benzoic acids as a liquid crystal intermediate. Chemical structures and liquid crystal behavior of the compounds were characterized by elemental analysis, 1H NMR spectroscopy, DSC and polarizing microscopy. All the compounds, except Ⅰf, exhibit thermotropic liquid crystalline properties.
