| Abstract: | ![]()
The reaction of Schiff"s base L with lanthanide alkylsulfates affords liquid crystalline complexes with the general formula L3Ln(CnH2n+1OSO3)3. The liquid crystalline structure and magnetic properties are studied by polarization thermal microscopy, differential scanning calorimetry, X-ray diffraction, and measurement of magnetic susceptibility. The temperatures of the existence of the mesophase and magnetic anisotropy of the complexes with the same lanthanide depend on the chain length of the alkyl fragment in the sulfate anion. |
