DIELECTRIC-RELAXATION INVESTIGATIONS OF NEW SYNTHESIZED ORGANOMETALLIC LIQUID-CRYSTAL

An impedance spectroscopy experimental characterization of a new synth etized Palladium complex organo-metallic liquid crystal is reported. I t has been found that although organo-metallic complexes modify some o f the physical properties of the liquid crystals, namely transition te mperatures, values of the relaxation times and conductivity, they stil l have, in the nematic phase, the general behaviour of the usual liqui d crystals. In particular the low frequency conductivity is very small , so one can conclude that the considered organo-metallic liquid cryst al behaves like a good insulator. The temperature dependence of the st atic parallel and perpendicular components of the dielectric tensor ar e reported.
