【摘要】 本文详细讨论分子中共轭π电子对液晶材料介电各向异性的影响。分析了3种典型液晶(CB-7,PCH-7,CCH-7)分子的π电子的分布情况,得出3种液晶的介电各向异性的关系,并与实验结果相符合。本文为正确选择电光锐度良好的液晶材料提供了可靠的依据。更多还原

【Abstract】 This paper has discussed the effect of the moleculer conjugate π-electrons on the dielectric anisotropy of liquid crystal materials. It has analysed the a-electron distribution states of the typical liquid crystals (CB-7, PCH-7, CCH-7), whose dielectric anisotropy relations were obtained and correspond to the experimental results.更多还原
