GRAPHICAL ABSTRACT ABSTRACT Two nonlinear hockey stick shaped homologous series based on three linking groups have been synthesized and characterized by elemental analyses and spectroscopic techniques. The mesomorphic properties of these compounds were observed by polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). In this present investigation, we have synthesized two
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。
