Dielectric properties of several recently synthesized compounds with various LC phases

Abstract

Results of dielectric studies (static and dynamic) carried out on several new synthesized substances (in most cases the tolane derivatives) are presented. Apart from pure substances the mixtures of two or more components were also studied. The dielectric properties: tensor components of the permittivity, the dielectric anisotropy, low and high frequency relaxation times are analyzed in view of dipole structures of molecules and the liquid crystalline phases occurred.
