摘　　要：本文简述了含氟液晶的研究进展。根据小分子含氟液晶中氟原子或含氟基团的位置不同,将其分为3类:末端是氟原子或含氟基团的液晶、苯环上氢原子被氟原子取代的液晶、中心桥键上的氢原子被氟原子取代的液晶。根据小分子含氟液晶特点,归纳了氟原子或含氟基团对液晶分子物理性质的影响。对高分子含氟液晶的研究进展也做了介绍。The progress in study of the fluorinated liquid crystals is reviewed. Based on the different positions of fluorine atoms or fluorinated groups on low molecular mass liquid crystals, they are classified in three species： liquid crystals bearing fluorine atom or fluorinated groups as terminal groups, liquid crystals containing benzene ring with hydrogen atoms substituted by fluorine atoms, and liquid crystals with central bridge bond having hydrogen atoms substituted by fluorine atoms. The effects of fluorine atoms and fluorinated groups on physical properties of liquid crystals are discussed according to characteristics of low molecular mass liquid crystals. The progress of fluorinated liquid crystalline polymers is also reviewed in brief.
