Two homologous series of unsymmetrical alkylated chalcones and 3,5-diaryl isoxazoles, consisting of 20 members, with various n-alkyl bromides (n=2−7, 10, 12, 14, 16) have been synthesized and studied for their liquid crystalline property. Simple strategy was employed to achieve the target materials. Flexibility in the synthesized molecules is provided by attaching straight alkoxy chains, where one
合成了两个同源系列的不对称烷基化查耳酮和3,5-二芳基异恶唑(由20个成员组成)和各种正烷基溴化物(n = 2-7、10、12、14、16),并研究了它们的液晶属性。采用简单的策略来实现目标材料。通过连接直的烷氧基链来提供合成分子的柔韧性,其中一个末端基团是固定的,而另一个末端基团是变化的。基于质谱,IR和NMR光谱对合成的化合物进行表征。中间相的稳定性和范围随异恶唑上链长的增加而增加。熔点 合成了两个同源系列的不对称烷基硫族元素和3,5-二芳基异恶唑,并通过偏光显微镜(POM)和差示扫描量热法(DSC)进行了表征。
