  摘要：

  一个新的同源系列由 12 种化合物组成。较短链的同系物不显示液晶相，但从六个碳开始，向列相呈现对映性，一些成员还显示近晶相。该系列的过渡曲线的相行为显示出通常的趋势。向列相的织构为螺纹或纹影型，近晶相的织构为近晶 A。对于近晶-向列和向列-各向同性转变曲线观察到奇偶效应。分析数据证实了分子结构。转变温度由光学偏光显微镜确定。将新系列的介晶特性与结构相似的同源系列进行比较。平均近晶-向列和向列-各向同性热稳定性分别为 133.4°C 和 159.8°C，

  One chalcone-ester homologous series of mesogens -4-[4(/)-n-alkoxybenzoyloxy phenyl -4(//)methoxy benzoyl ethylenes (A) and one azo-ester homologous series of mesogens p-(p(/)-n-alkoxybenzoyloxy) phenyl azo-p(//)-methoxy benzene (B) being structurally similar are discussed. Both series (A) and (B) differ in respect of central bridges linking two phenyl rings. Mesomorphic properties start from 6th and 1st member of series (A) and (B) respectively. In series (A), 6th to 12th members show both smectogenic and nematogenic properties, and the 14th and 16th members show only nematogenic property. While in series (B), 1st to 10th members show nematogenic properties, 11th member shows both smectogenic and nematogenic properties, while 12th member shows only smectogenic property. Thermal stability of series (A) is relatively high as compared to series (B). Transition temperatures are observed through hot stage polarizing microscope by the miscibility method. Analytical data support the structure of molecules. Textures of series (A) in nematic are threaded and Schlieren in SmecticSmectic A type, while that of series (B) in nematic are threaded in SmecticSmectic A and smectic C.
