  摘要：

  图形摘要 摘要 基于三个连接基团的两个非线性曲棍球棒形同源系列已被合成并通过元素分析和光谱技术表征。通过偏光显微镜（POM）和差示扫描量热法（DSC）观察这些化合物的介晶性质。在本次调查中，我们合成了两个同源系列，即。2-((3-苯基亚丙基)氨基)苯基4-((4-n-烷氧基亚苄基)氨基)苯甲酸酯(series-1)和4-((2-((3-苯基亚丙基)氨基)苯氧基)羰基) 苯基-4-n-烷氧基苯甲酸酯（系列 2）。这两个系列在第一连接基团方面是不同的。在系列 1 中，comp.C4-C18 显示向列相和近晶相，而在系列 2 中，comp.C10-C16 显示近晶相和向列相，而 comp.C4-C18 仅显示向列相。

  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).
