  液晶基团中含有联苯基的液晶苯并恶嗪的合成

  摘要：

  在这项工作中，我们描述了一种从液晶苯酚中合成新型液晶（LC）苯并恶嗪的方法，该苯酚在介晶部分，各种烷基胺和甲醛中含有联苯，酯和甲亚胺基团。通过差示扫描量热法和偏振光学显微镜研究了含联苯的苯并恶嗪的LC行为，并将其与介晶部分中包含苯基，酯和偶氮甲胺基团的类似的含苯基的LC苯并恶嗪进行了比较。含有苯基的LC苯并恶嗪在加热时仅表现出向列相，而含有联苯基的LC苯并恶嗪具有近晶相和向列相。此外，LC各向同性转变温度比含苯基LC苯并恶嗪的转变温度高100℃以上。通过将含联苯的LC苯并恶嗪在180°C下固化1小时获得的膜表现出双折射。最后，还研究了固化的LC苯并恶嗪的热扩散率。

In this study, both (R) and (S) forms of novel chiral dopants were synthesized, showed extremely high helical twisting power values in nematic LC compounds, and induced stable BPs with a small amount of our chiral dopants (3–5 mol %).

  This article reports new results on synthesis and mesomorphic properties of the homologous series of (S)-1-methylheptyl-4-(4'-alkyloxybiphenylthiocarboxy)-benzoates, referred to as (S)-MHPSBOn, where Ovaries from 7 to 10 and denotes the number of carbon atoms in the alkyl chain. These compounds are sulphur analogous to a liquid crystal known as MHPOBC, where the central ester bridge was replaced with the -COS- connecting group. The (S)-MHPSBOn homologous series possesses enantiotropic SmA*, SmC*, SmCA* and monotropic Sml(*) phases for n = 7-10. The (S)-MHPSBO7 compound has also smectic chiral subphases: SmC alpha*, and SmC gamma*. Their mesomorphic properties were investigated by means of polarizing optical microscopy (ROM), differential scanning calorimetry (DSC). transmittance light intensity (TLI). X-ray diffraction and electro-optic (DO) measurements. (C) 2010 Elsevier B.V. All rights reserved.
