ABSTRACT A novel homologous series of N-[4-[4′-n-alkoxy)benzoyloxy-2-hydroxybenzylidene)-4-carbethoxy anilines, H2n+1CnOC6H4C(O)OC6H3(OH)C(H)˭NC6H4COOC2H5 (n = 6, 8, 10, 12, 14, 16) and their copper(II) complexes have been synthesized. All these compounds have been characterized by suitable spectroscopic techniques. The mesomorphic properties of these compounds were investigated by differential scanning calorimetry
摘要 N-[4-[4'-n-烷氧基)苯甲酰氧基-2-羟基亚苄基)-4-甲氧基苯胺,H2n+1CnOC6H4C(O)OC6H3(OH)C(H)˭NC6H4COOC2H5 (n = 6, 8, 10, 12, 14, 16) 及其铜 (II) 络合物已被合成。所有这些化合物均已通过合适的光谱技术表征。通过差示扫描量热法 (DSC) 和偏光显微镜 (POM) 研究了这些化合物的介晶性质。这些配体表现出广泛的对映性近晶 A 和向列相,这由它们在偏光显微镜下的典型光学结构所证实。配体的方形平面铜 (II) 配合物在较高温度下仅显示各向同性相,未观察到介晶性质。
