Title:
NOVEL COMPOUND HAVING CYCLIC STRUCTURE WITH NEGATIVE DIELECTRIC ANISOTROPY, METHOD FOR PRODUCING SAID COMPOUND, LIQUID CRYSTAL COMPOSITION, AND LIQUID CRYSTAL ELECTROOPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/125924
Kind Code:
A1
Abstract:
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 Δε value, which has a negatively large Δε 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).
