摘要
通过SiCl4 的Si—Cl键与偶氮苯类液晶基元末端OH的有效联接 ,合成了三种新的星型液晶 ,利用红外光谱 (IR)、核磁共振 ( 1HNMR)对其分子结构进行了鉴定 ,利用偏光显微镜 (POM)和示差扫描量热法 (DSC)对其液晶相行为进行了表征 ,并对其在毛细管气相色谱分析中的应用进行了初步探讨 .
Using Si-Cl bond linking with rear OH of azobenzene mesogenic units, three types of novel star-shaped liquid crystals were synthesized from SiCl4. The structures of these molecules were established by infrared absorption spectroscopy (IR) and nuclear magnatic resonance spectroscopy (NMR). Their liquid crystalline phase behaviors were characterized by polarized microscopy (POM) and differential scanning calorimeter (DSC). The applications of these compounds as stationary phases for capillary column gas chromatography are also discussed briefly.
