Abstract

The bent-core nematic liquid crystals discovered in recent years is a new kind of liquid crystals with special electro-optical property.The molecules have the unique bent shape,performing great characteristics which are different from rod-like liquid crystals.However,these molecules with bent-core nematic commonly have high melting point and wide temperature range of smetic phases.This paper overviews the current state of research in the field of bent-core nematic liquid crystals of molecular structures,properties and the research situation of bent-core molecules with nematic phases based on the substituted resorcinol,naphthalene,oxadiazole etc as the central units and ester group,C=N(N=N) etc as the bridge bonds,and the influence of lateral substitution on the liquid crystal behavior was given.
