  Synthesis and Mesomorphic Investigations of Liquid Crystalline Compounds Having a Benzothiazole Ring

  摘要：

  Two homologous series of calamitic liquid crystals containing a benzothiazole ring and two different linkages have been prepared, and their liquid crystalline properties are studied and compared with each other and those of similar structure. The mesogens with only the cinnamate linking group showed better thermal properties than those with an ester. Nematic and smectic phases were observed. All the compounds of both the series were characterized by elemental analysis, FT-IR, mass spectrometry, H-1-NMR, and C-13-NMR. Phase transition temperatures and the thermal parameters were obtained from differential scanning calorimetery (DSC). The textural observations were performed using hot-stage Polarizing Optical Microscopy (POM).

  查耳酮连接的双肉桂酸酯基液晶的合成与表征：结构-性质关系

  摘要：

  摘要 设计并合成了基于查尔酮和肉桂酸酯基团的棒状材料，用于研究液晶特性。在本研究中，通过改变烷氧基侧链合成了七种同系物，并通过 POM、DSC 和 XRD 研究初步研究了液晶性质。较低的烷氧基链显示向列中间相，而较高的链显示近晶 C 和向列介晶行为。此外，还通过改变末端烷氧基链研究了结构-性能关系。采用红外光谱、1H NMR、13C NMR等分析方法对化合物的分子结构进行了确证。

  Two new mesogenic homologous series of Schiff base esters, 2-[4-(4'-n-Alkoxy benzoyloxy) benzylidenamino] 3-cyno thiophine (Series-A) and Schiff base cinnamates, 2-[4(4'-n-alkoxy cinnamoyloxy) benzylidenamino] 3-cyano thiophene (Series-B), comprising a thiophene moiety were synthesized. Structural elucidation was carried out using elemental analysis and spectroscopic techniques such as FT-IR, H-1-NMR and C-13-NMR, and mass spectrometry. The mesomorphic properties and thermal stabilities of the title compounds were studied by using differential scanning calorimetry and optical polarizing microscopy. All the derivatives are mesomorphic in nature showing the nematic phase, and the higher members of Series-A show a smectic C phase whereas Series-B exhibits only the nematic mesophase. The mesomorphic properties of the present series are compared with other structurally related compounds.
