摘要：

Complexes of the composition L(LH)(2)Ln(NO3)(2) (Ln La, Dy, Gd, Er, Eu, or Tb) were obtained by the reaction of beta-aminovinyl ketone (LH) with rare earth metal nitrates. All the compounds synthesized are thermotropic liquid crystals having the smectic S-A phase. The values of magnetic anisotropy of these complexes measured by magnetic birefringence are fairly high.
