摘要

苯并呋喃类液晶的合成是以烷基苯酚为原料

经氯仿甲酰化

得到取代水杨醛

由此可合成出取代的苯并呋喃

进而可合成出一系列苯并呋喃类液晶。目标化合物经H

NMR、MS和元素分析

确认了分子结构。液晶的相变温度通过差热扫描仪测定

测量结果为熔点

=83.66 ℃;清亮点

=145.42 ℃。

Abstract

Benzofuran liquid crystals were synthesized in the base of alkylphenels by formylating chloroform. The intermediate compound which called substitute salicylie aldehyde would be produced. In this way

substitute benzofuran could be obtained.Thereby a series of benzofuran liquid crystals would be synthesized.The structures of liquid crystal compounds were confirmed by H

NMR and MS

the phase transition temperature was measured by DSC.Transition temperatures are

=83.66 ℃;

=145.42 ℃.
