【Abstract】 The Schiff_base_type liquid crystal containing terminal olefinic bond (Schiff_C 11 C 10 ) and its Pd(II) complex (Schiff_C 11 C 10 _Pd) containing chlorine_bridged groups were synthesized and characterized by means of elemental analyses, molar conductivity, IR, UV and 1H NMR. The complex is non_electrolyte. The molar ratio of the ligand to Pd(II) is 1∶1.The liquid crystalline properties of the ligand and the complex were determined by polarizing microscopic observation. Both the ligand and the complex are all thermotropic liquid crystals. The texture of the ligand is tentatively supposed to be a pattern of mosaic and that of the complex is a pattern of broken_fan.更多还原
