  摘要：

  A new series of achiral banana-shaped compounds ("S-n'') has been synthesised and studied by the classical techniques (optical microscopy, differential scanning calorimetry, X-ray diffraction and electro-optic investigations). The short homologues (S-6,S-7) present an intercalated smectic B6 and a two-dimensional B1 phase. The intermediate S-8-S-10 compounds only form a B1 phase while the mesophase of long homologues (S-11-S-16) is identified as a switchable smectic B2 mesophase.

• Biaxial smectic A phase in homologous series of compounds composed of highly polar unsymmetrically substituted bent-core molecules

  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, Mesomorphic Behaviour and the Uniaxial Nature of 1,2,4,5-Tetra-(4-Alkoxybenzoyloxy) Benzenes

  A homologous series of 1,2,4,5-tetra-(4-alkoxybenzoyloxy)benzenes (2, R = C4H9, C6H13 to C16H33 and C18H37) has been synthesised. Optical microscopy revealed that the compounds with R = C4H9, C6H13 to C10H21 have a nematic phase, compounds with R = C11H23 to C14H29 have nematic and smectic C phases and compounds with R = C15H31, C16H33 and C18H37 have only a smectic C phase. The T-N-I values show an 'odd-even' alternation which is typical of calamitic systems. The refractive indices for aligned samples of compound 2h (R = C10H21) demonstrate that the nematic phase is uniaxial.
