  摘要：

  Liquid crystalline lanthanide complexes with N-aryl-substituted beta-aminovinyl ketones were synthesized for the first time. The complexes give rise to smectic A mesophase and are stable only in the solid state; in going to solution, they dissociate with formation of the initial ligand.

  Three new series of compounds 1a–c containing multiple heterocyclic 2,5-pyrazoles, 1,3,4-oxadiazole and thiophene exhibiting mesophases were reported. Crystallographic data showed that the crystal 1a (n=8) is a linear-shaped molecule with a molecular length of ca. 40.57 Å. However, three heterocyclic rings were not coplanar. All compounds 1a formed smectic A/C phases, and all compounds 1c exhibited columnar

  of bis-(boron difluoride) complexes 1a–c derived from substituted tetraketonates 2a–c are reported, and their mesomorphic and optical properties have been investigated. Two single crystals of mesogenic ligand 2a (n = 6) and nonmesogenic diboron complex 1a (n = 14) were obtained, and their single crystal and molecular structures were resolved. Results show that all 2a ligands (n = 6, 8, 10, 12, 14) formed
