一种含有环戊烷并噻吩类液晶分子的液晶组合物
摘要：
本发明公开了一种含有环戊烷并噻吩类液晶分子的液晶组合物，其特征在于包含一种或多种的结构通式(1)的化合物：其中，R1为碳数1～9的直链烷基、烯基；n，m分别为＝0、1；A1、A2、A3为氢原子或氟原子；环B为苯环或反式-环己烷；R2为F原子(F)、氯原子(Cl)、氰基(CN)、异硫氰基(NCS)、三氟甲氧基(OCF3)、三氟甲基(CF3)、碳数1～9的直链烷基。本发明的液晶组合物，具有低温相容性好、液晶相区宽泛、双折射率较高等特点，适用于多种显示模式的液晶显示装置中去，尤其适用于TN、STN、FFS等模式的液晶显示器。此外，本发明的液晶组合物还可应用于使用高双折射率液晶材料的其它光学器件。
摘要（英）：

The invention discloses a liquid crystal composition containing cyclopentane bithiophene liquid crystal molecules. The liquid crystal composition is characterized by containing one or more compounds with the structural general formula (1) (please see the specification for the formula), wherein R1 is linear-chain alkyl and alkenyl with the carbon number of 1~9; n and m are respectively equal to 0 and 1; A1, A2 and A3 are hydrogen atoms or fluorine atoms; the ring B is a benzene ring or trans-cyclohexane; and R2 is F atoms (F), chlorine atoms (Cl), cyan (CN), isothiocyanato (NCS), trifluoromethoxy (OCF3), trifluoromethyl (CF3) and a linear-chain alkyl with the carbon number of 1~9. The liquid crystal composition has the characteristics of good low temperature compatibility, wide liquid crystal phase area and high birefringence index, is applicable to liquid crystal display devices of various display modes, and especially to liquid crystal display devices of TN, STN, FFS and other modes.In addition, the liquid crystal composition can also be applied to other optical devices using high birefringence liquid crystal materials.
