  席夫碱与三（β-二酮）镧系元素（III）配合物的加合物：结构和液晶行为

  摘要：

  描述了席夫碱 2-羟基-N-十八烷氧基-4-十四烷氧基苯甲亚胺与三 (β-二苯甲酰基甲烷) 镧系元素 (III) 配合物的加合物。配合物的化学计量为 [Ln(dbM)(3)Lx]，其中 Ln 是三价镧系离子（除 Ce 和 Pm 外的所有镧系元素），Hdbm 是二苯甲酰甲烷，L 是席夫碱；对于 Ln = La-Er，x = 2，对于 Ln = Tm-Lu，x = 1。席夫碱配体呈两性离子形式，仅通过酚氧配位。描述了 [La(dbm)(3)L'(2)] 的 X 射线单晶结构，其中 L' = N-丁基-2-羟基-4-甲氧基苯甲亚胺。镧 (III) 配合物的溶液结构已通过一维和二维 H-1 核磁共振技术进行了研究。尽管长链席夫碱配体和三（β-二苯甲酰甲烷）镧系元素（III）配合物是非介晶的，一些加合物表现出单向性近晶 A 相。介晶行为取决于镧系元素离子，从某种意义上说，对于系列 Ln = La-Eu

  Rare-earth-containing metallomesogens with 4-alkoxy-N-alkyl-2-hydroxybenzaldimine ligands are reported. The stoichiometry of the complexes is [Ln(LH)(3)(NO3)(3)], where Ln is the trivalent rare-earth ion;(Y, La, and Pr to Lu, except Pm) and LH is the Schiff base. The Schiff base ligands are in the zwitterionic form and coordinate through the phenolic oxygen only. The three nitrate groups coordinate in a bidentate fashion. The X-ray single-crystal structures of the nonmesogenic homologous complexes [Ln(LH)(3)(NO3)(3)]where Ln = Nd(III), Tb(III), and Dy(III) and LH = CH3OC6H3(2-OH)CH=NC4H9, are described. Although the Schiff base Ligands do not exhibit a mesophase, the metal complexes do (SmA phase). The mesogenic rare-earth complexes were studied by NMR, IR, EPR, magnetic susceptibility measurements, X-ray diffraction,and molecular modeling. The metal complexes in the mesophase have a very large magnetic anisotropy, so that these magnetic liquid crystals can easily be aligned by an external magnetic field.

  The synthesis and mesophase behaviour of lanthanide complexes with azomethine (Schiff base) ligands is described. The ligands are 4-tetradecyloxy-N-alkyl-2-hydroxybenzaldimines, where the alkyl chain on the imine nitrogen is C8H17, C12H25 or C18K37. The stoichiometry of the complexes formed by the reaction of the hydrated nitrates of the lanthanides with the azomethines is [Ln(LH)(3)(NO3)(3)]. All these coordination compounds exhibit liquid-crystalline properties. A viscous smectic A (SmA) mesophase is formed. The mesophase of these metallomesogens can be supercooled to a glassy state.
