Lanthanide complexes L"3Ln(ROSO3)3 are synthesized with Ln(III)=Eu, Tb, Dy, Ho, Er, Tm, Yb; L"=4-tetradecyloxy-N-octadecyl-2-hydroxybenzaldimine and perfluoro-substituted alkylsulfate anion as counterion (where R=CF3(CF2)(8)CH2). Their IR spectra are described. The synthesized compounds are studied by the polythermal polarizing microscopy and differential scanning calorimetry. The title complexes are thermotropic liquid crystals that exhibit smectic a SmA mesophase.
