New ferroelectric liquid crystalline substances with lateral groups in the core

Article abstract of DOI:10.1080/10587250108023995

New series of ferroelectric liquid crystalline materials containing methyl and methoxy lateral groups on the aromatic ring of the core unit, as well as non-substituted materials have been synthesised. All compounds exhibit a wide temperature range of the ferroelectric chiral SmC* phase. A low temperature ferroelectric phase was detected for some of the investigated compounds probably composed of the SmC* phase and a crystalline phase. Measurements of spontaneous polarisation and tilt angle, helical pitch and dielectric permittivity has been performed.
