摘要
以4-(反式-4’-n-烷基环己基)苯甲酸和S(+)-(2-甲基丁基)4-羟基苯甲酸酯为原料,合成了一个新系列光活性苯基环己烷液晶。其结构用核磁共振氢谱、红外光谱确定。并对该系列液晶的相变温度和显微织构进行了研究。
In this paper, a new series of optically active phenylcyclohexyl liquid crystals were synthesized using 4- (trans-4'-n-alkylcyclohexyl) benzoic acids and (2-methyl butyl) 4'-hydroxybenzoate as starting materials. Their structures were determined by using NMR-H1 and IR. The transition temperatures and the phase sequence were also investigated.
