【摘要】 二芳基取代乙炔类化合物是一类应用广泛的液晶材料,主要用于改善混合液晶的双折射率。依据近似加法规则,着重考察了分子结构中环己基的引入对液晶光电性能的影响规律,实验结果显示,引入环己基有利于增大液晶的双折射率和阈值电压。更多还原

【Abstract】 As one of widely used liquid crystals, tolans are mainly used for improving birefringence of liquid crystal composition. Effects of cyclohexyl group introduced into molecule on the electro-optical pro-perties of tolan were investigated. The results show that the threshold voltage and birefringence of the composition can be increased by introducing cyclohexyl group into molecule.更多还原
