  Several compounds belonging to three new series of five-ring banana-shaped esters, which are unsymmetrically substituted with respect to the central phenyl ring, have been synthesised. One of the arms of these bent-core molecules has been terminally substituted with a highly polar cyano group while the other end contains an alkoxy chain. The mesophases exhibited by these compounds have been characterised using a combination of optical polarising microscopy, differential scanning calorimetry and X-ray diffraction studies. These studies indicate that most of the compounds show two smectic A mesophases which have a partial bilayer ordering. Conoscopic experiments clearly reveal that the lower temperature smectic A phase is biaxial in nature. A structural model has been proposed for the lower temperature biaxial smectic A phase. It is argued that quartets of molecules, which are conducive to the formation of the biaxial phase, can form in the layers. The in-layer birefringence of the biaxial smectic A phase has also been measured as a function of temperature for one of the compounds.

  我们合成了属于三个新的五环香蕉形酯系列的几种化合物，这些化合物的中心苯基环被非对称取代。这些弯曲核心分子的一个臂末端被高极性氰基取代，而另一端则含有烷氧基链。通过结合使用光学偏振显微镜、差示扫描量热法和 X 射线衍射研究，对这些化合物的介相进行了表征。这些研究表明，大多数化合物显示出两种具有部分双层有序性的 A 介相。显微镜实验清楚地表明，温度较低的共晶 A 相具有双轴性质。为低温双轴共晶 A 相提出了一个结构模型。该模型认为，有利于形成双轴相的分子四元组可以在层中形成。还测量了其中一种化合物的双轴共晶 A 相的层内双折射随温度变化的情况。

  The synthesis and characterisation is reported of a low molecular weight organic compound to exhibit the biaxial smectic A (SmA(b)) phase, which shows a transition from the partial bilayer uniaxial SmA(d) phase to the SmA(db) phase as the temperature is lowered.

  The synthesis and characterization of twenty seven new compounds belonging to three homologous series of compounds derived from 3-hydroxybenzoic acid are reported. One of the terminal positions of the constituent molecules of these compounds is substituted with a strongly polar cyano group while the other end contains an n-alkyl chain attached to a biphenyl moiety. Twenty two of these compounds show the polar partial bilayer biaxial smectic A phase which is antiferroelectric in nature. In addition, a direct transition from the nematic phase to the polar partial bilayer biaxial smectic A phase which has not been seen before is also reported. The mesophases have been characterized using polarized light optical microscopy, differential scanning calorimetry, X-ray diffraction studies and electro-optical experiments.
