| 摘 要： | 通过重氮化反应合成了末端为磺酸基的刚性基元,再经过取代、加成、酯化反应最终合成了偶氮苯类聚硅氧烷液晶。通过UV表明其具有类似小分子的光致变性。并用POM、DSC对其液晶行为进行了表征,结果表明该化合物属于近晶A型液晶,相变区间为191.04—274.95℃,液晶范围较宽,有望作为光控开关和新型信息存储材料。 |

| Abstract: | The rigid mesogenic unit with extremity sulfonic acid was synthesized by diazotization,then azo benzene micro-powder assorts liquid crystal was synthetized through substitution,addition and esterification reactions.The photochromism of similar micromolecule was obtained by UV,and the liquid crystalline behavior was characterized by polarizing microscopic observations and differential scanning calorimeter,and the compound was smectic A with phase transition range from 191.04℃ to 274.95℃,that had wide liquid crystal,and will become a new type light-operated switch and information storage material. |
