差示扫描量热法(DSC)研究芳羧酸酯类冠醚的液晶性质

DSC Study On liquid Crystalline Properties of Aromotic Carboxylic Esters' Crown Ether

本文用差示扫描量热法(DSC)研究了芳羧酸酯类冠醚在升温和降温过程中的相转变情况,发现有的化合物是液晶,而有的却不是。液晶性质的差异是由分子结构所决定的。

The phase transitions of Aromatic Carboxylic Esters' Crown Ether in heating and cooling were studied by DSC. The results showed that some compounds were liquid crystal, but others were not. The liquid crystalline properties depends on the molecular structure.
