摘要：
The molecular structure and physical properties of the rare earth metal complexes differ from the structure and properties of known calamitic liquid crystals. In this connection, great interest is the behavior of metallomesogenic complexes in the area near the phase transition mesophase - isotropic phase. Therefore, in the present study we examined the pretransitional properties of the newly obtained metallomesogen - tris(beta-diketonate) ytterbium adduct. The electric birefringence of the isotropic melt and the temperature dependences of the dielectric and optic anisotropies in the mesomorphic state were investigated. The properties above and below the transition temperature nematic - isotropic phase were compared with the use of the Landau - de Gennes theoretical model.
