  具有查耳酮酯和侧氟取代基的棒状分子的合成和介晶性质

  摘要：

  图形摘要 在本研究中，我们合成了一类新的化合物，其中包含查耳酮和侧向取代的氟基团。合成了一系列具有五个芳环的新型查耳酮，并通过元素分析和光谱技术，如傅里叶变换红外 [FT-IR] 和质子磁共振磁共振 [1H NMR] 光谱进行表征。这些化合物的介晶性质通过光学偏光显微镜 (POM) 观察并通过差示扫描量热法 (DSC) 确认。发现除了本系列中的前三个同系物外，所有制备的材料都显示出对映性 LCs 相。较低的同系物（n = 4 至 12）显示 SmC 和向列相，而在较高的同系物（n = 14 至 18）中，仅在加热和冷却条件下看到 SmC 相。

  New chalcone based liquid crystals with allylidene amino linking unit: Synthesis and characterization

  摘要：

  In this study, the synthesis, structural characterization and mesomorphic properties of newly thirteen calamitic shaped compounds derived from allylidene amino chalcone and 4-n-alkoxy benzoyloxy benzoic acid. Comp.H-1 to H-3 exhibited nonliquid crystalline nature, while comp.H-4 to comp.H-18 displayed enantiotropical smectic C phase. Phase transition temperatures of present synthesised compounds were determined by optical polarising microscopy (POM), differential scanning calorimetric (DSC) and powder X-ray diffraction (PXRD) techniques. Thermal stabilities of smectic to isotropic phase are 150.0 degrees C and temperature range of mesophase is in decreasing order from comp.H-3 to comp.H-18 respectively. The presences of SmC phase are the type of broken fan and needle type in present synthesized series. It is also shown that presence of chalcone amino allylidene central linking group favors a calamitic liquid crystalline behaviour in molecules with lower member to higher member aliphatic side chain in alkoxy group (-OR).
