mesomorphism in four binary systems comprising two azo-ester mesogens, viz. 4-(4′-n-alkoxybenzoyloxy)3-methylphenyl azo-2″ and 4″-dimethylbenzenes (where n-alkoxy is n-butoxy or n-hexyloxy), and two ester nonmesogenic and mesogenic components, viz. 4-nitrophenyl-4′-n-alkoxybenzoates (where n-alkoxy is n-butoxy or n-hexyloxy). All the four binary systems are mesogenic in nature, showing nematic phase with threaded/marble
我们研究了包含两个偶氮酯介晶的四个二元系统中的混合介晶现象,即。4-(4'-n-烷氧基苯甲酰氧基)3-甲基苯基偶氮-2”和4”-二甲基苯(其中n-烷氧基是正丁氧基或正己氧基),以及两种酯非介晶和介晶组分,即。4-硝基苯基-4'-n-烷氧基苯甲酸酯(其中n-烷氧基是正丁氧基或正己氧基)。所有四个二元系统本质上都是介晶的,显示出具有螺纹/大理石纹理的向列相。绘制了二元系统的相图,并确定了所有系统中向列中间相的共晶转变温度和最大中间相范围。
