Abstract

Preliminary results of the dielectric studies of seven members of the nBT (4-alkyl-4'-isothiocyanatobiphenyl, n equals 4 divided by 10) homologous series are presented. The dependence of the static permittivity (epsilon) _S, the longitudinal relaxation time (tau) _(parallel) and (Delta) H_(parallel)) indicate a hardening of this solid-like smectic phase with shortening of the alkyl chain.
