Fluorinated smectic liquid crystals each with a biphenyl benzoate rigid core are investigated. Molecular structures of the studied compounds have difference only in fl uorine position and the length of the carbon chain. Dielectric relax-ation study and electro-optical measurements are carried out with the classical SSF LC geometry. The field-induced phase transitions are studied and the (E , T ) phase diagram is established.
