Dielectric spectroscopy of the SmQ* phase

Original language description

Liquid crystalline (LC) material possessing two biphenyl moieties in the molecular core and lateral chlorine substitution far from the chiral chain has been studied by the broadband dielectric spectroscopy within frequency range 100 Hz-2 MHz. On coolingfrom the isotropic phase, the material possesses the frustrated smectic Q* (SmQ*) and the antiferroelectric smectic (SmCA*) phases within a broad temperature range. It has been confirmed by dielectric spectroscopy that the SmQ phase is closely related toSmCA* antiferroelectric phase. Only one relaxation process has been observed in the SmQ* phase, while in the SmCA* phase two relaxation are clearly detectable. It seems that mode found in the SmQ is connected with high frequency anti-phase mode observedin the SmCA* phase; this mode is weaker and faster than that in the SmCA* phase.
