Abstract In present study, we have synthesized two homologous series of some new Schiff base of 4-n-alkoxy-2-hydroxy benzaldehyde (n = 2–8, 10, 12, 14, 16, 18) with 4-amino acetanilide and their corresponding Cu(II) complexes. A series of new Schiff base containing two aromatic rings have been synthesized and characterized by various spectroanalytical techniques including FT-IR and 1H NMR. The mesomorphic properties of these compounds were observed by optical polarized light microscopy (POM) and confirmed by differential scanning calorimetry (DSC) study. It has been observed that all the newly synthesized compounds exhibit wide range SmA phase.

一些新的席夫碱同系物及其Cu(II)配合物的合成、表征和介晶性质

摘要 在本研究中,我们合成了 4-n-烷氧基-2-羟基苯甲醛(n = 2–8, 10, 12, 14, 16, 18)与 4-氨基乙酰苯胺和它们相应的 Cu(II) 配合物。合成了一系列含有两个芳环的新型席夫碱,并通过包括 FT-IR 和 1H NMR 在内的各种光谱分析技术进行了表征。这些化合物的介晶性质通过偏振光显微镜 (POM) 观察并通过差示扫描量热法 (DSC) 研究证实。已经观察到所有新合成的化合物都表现出宽范围的 SmA 相。
