NOVEL COMPOUND HAVING CYCLIC STRUCTURE WITH NEGATIVE DIELECTRIC ANISOTROPY, METHOD FOR PRODUCING SAID COMPOUND, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL ELECTROOPTICAL ELEMENT

摘要

The purpose of the present invention is to provide: a novel compound which contains a cyclic structure capable of developing a function and has a negative &Dgr;&egr; value, which has a negatively large &Dgr;&egr; value and can be used for the development of a liquid crystalline compound that is chemically stable, has excellent compatibility with other liquid-crystalline materials or non-liquid-crystalline materials and can have properties including high-speed response, a low viscosity, a broad liquid crystal temperature range and a high clear point depending on the ways of designing of a binding group to a linking group; a method for producing the compound; a liquid crystal composition containing the compound; and a liquid crystal electrooptical element. The present invention provides a compound represented by formula (1).
