摘要
合成了4-(丙烯酸乙氧基酯)苯甲酸,4-(丙烯酸乙氧基酯)苯甲酰氧基苯甲酸等系列液晶中间体。首次合成了4-(丙烯酸乙氧基酯)苯甲酰氧基苯甲酸基元的含氟侧链高分子液晶,采用IR,1HNMR和19FNMR表征了其分子结构。通过DSC分析和偏光显微镜研究了含氟侧链高分子液晶的织构形态。结果表明,4-(丙烯酸乙氧基酯)苯甲酰氧基苯甲酸基元含氟侧链高分子液晶具有向列型液晶的织构形态。4-(丙烯酸乙氧基酯)苯甲酰氧基苯甲酸基元含氟侧链高分子液晶,其液晶温度范围较宽,随着液晶基元成分的降低,含氟侧链成分的增加,高分子液晶玻璃化温度略有降低。
Some liquid crystal monomers were synthesized: 4-(acrylic ethoxy ester) benzoic acid, 4-(acrylic ethoxy ester) benzoyloxy benzoic acid. The fluoride has been introduced to the liquid crystal polymer according to bond polymerization reaction. 4-(acrylic ethoxy ester) benzolyloxy benzoic acid with the fluoride SLCP was synthesized. Their molecular structures were characterized through IR, 1HNMR, 19FNMR. The results show that 4-(acrylic ethoxy ester) benzolyloxy benzoic acid with the fluoride SLCP is the nematic liquid crystal texture patterns.
