摘要/Abstract

摘要：

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

关键词: smectic liquid crystal, dielectric relaxation, electro-optical properties, phase transition, (E,T) phase diagram
