  Biphenyl esters of the formula ##STR1## wherein X is --CO--O-- or --O--CO-- and R.sub.1 and R.sub.2 each are alkyl or alkoxy of 1 - 8 carbon atoms, enlarge significantly the temperature range of the nematic phase of liquid-crystalline compositions without adversely affecting other properties.

  Series II results from the ionic junction of the dendrimers to 1,2,4-oxadiazole-containing acids. The liquid crystalline behavior has been investigated by means of differential scanning calorimetry (DSC), polarizing optical microscopy (POM), and X-ray diffractometry (XRD). The liquid crystal properties are significantly improved in the dendrimers compared to the mesogenic precursors. The structural

  通过离子接枝聚（丙烯亚胺）PPI-（NH 2）x（x = 4，8，16，16，32，64）和聚（酰氨基胺）PAMAM-（NH 2）x（x＝ 64）已经合成了带有带有恶二唑环的羧酸，并且已经研究了它们的液晶性质。系列I是通过树枝状聚合物与含1,3,4-恶二唑的酸之间的离子附着而产生的。系列II由树枝状聚合物与含1,2,4-恶二唑酸的离子连接产生。已经通过差示扫描量热法（DSC），偏振光学显微镜（POM）和X射线衍射法（XRD）研究了液晶行为。与介晶前体相比，树枝状聚合物的液晶性质得到了显着改善。通过X射线衍射确定的结构参数反映了每种引入的含恶二唑酸所建立的不同的超分子组织。根据这些实验结果，提出了一种基于微观偏析现象和介晶单元之间相互交错程度可变的堆积模型。还研究了化合物的吸收和发射性质。据我们所知，这些是迄今为止结合恶二唑单元和液晶性质的第一批树枝状大分子。

  10 new rod-like azo benzoic acid liquid crystals belonged to three series have been prepared, in which trans-cyclohexyl benzene, biphenyl or bi-trans-cyclohexyl carboxylic acid mesogenic cores with ethyl, n-propyl, n-butyl or n-pentyl substituents were connected with azo benzoic acid. Meantime, a simple method was developed in synthesizing compounds bearing both ester and carboxyl groups in one-step reaction. All these compounds have been characterized on the basis of their spectral data, differential scanning calorimeter (DSC) and hot stage polarizing optical microscope (HS-POM). All these compounds have higher thermo-stability. 8 of these compounds have liquid crystalline properties. Their temperature ranges of mesophase have not been obtained, resulting from all the compounds decomposed before their clearing points. Although these compounds are photosensitive in solution under illumination of UV light (365nm), they can't do trans-cis isomerization in their mesophses, indicating the super stabilities of the trans isomer in mesophase.

  Ten new rod-like aromatic aldehyde liquid crystalline molecules with azo linkage were synthesized, in which bi(trans-cyclohexyl), cyclohexyl phenyl, and biphenyl carboxylic acid mesogenic cores with terminal ethyl, n-propyl, n-butyl, and n-pentyl substituents were esterified with azo benzoic aldehyde. These molecules were designed in an attempt to construct a series of new azo liquid crystalline molecules to investigate the influence of ultraviolet (UV) light on their mesophase. All compounds have been characterized on the basis of their spectral data, differential scanning calorimeter (DSC), and hot stage polarizing optical microscope (HS-POM). All these compounds exhibited liquid crystalline phase that belonged to nematic and photosensitive properties. Their temperature ranges of mesophase are from 101 degrees C to 150 degrees C. Under irradiated 365 nm UV light, they showed photosensitivity in the solvent of methanol. Observed under HS-POM, the UV light also did change the textures of these compounds. The result showed that terminal ethyl is enough for these molecules to exhibit wider temperature range of mesophase, and these new molecules have photosensitivities observed under illumination of UV light not only in solution but also in mesophase due to the change of their structures from trans isomer to cis one.
