In order to obtain low-temperature mesomorphic materials, thirty-two p-alkyl-p′-alkoxy-azo- and -azoxybenzenes have been synthesized. The former have been made by the condensation of p-n-alkylnitrosobenzenes and p-n-alkoxyanilines, and the latter, by the oxidation of the former. Twenty-nine of the compounds show nematic behavior. In the majority of cases, the nematic temperature range of the azoxy compounds, which have been considered to consist of two isomers synthesized simultaneously, is appreciably wide.
为了获得低温介形材料,我们合成了 32 种对烷基对烷氧基偶氮苯和偶氮氧苯。前者是由对-烷基亚硝基苯和对-烷氧基苯胺缩合而成,后者是由前者氧化而成。其中 29 种化合物显示出向列行为。在大多数情况下,偶氮氧基化合物的向列温度范围都很宽,它们被认为是由两种异构体同时合成的。
