Alcohol derivatives

摘要

A novel compound usable as a component constituting liquid crystal materials having a positive dielectric anisotropy value and a liquid crystal composition containing the same are provided, which compound is an alcohol derivative expressed by the general formula <IMAGE> (I) wherein R1 represents a hydroxyalkyl group of 1 to 10 carbon atoms having hydroxyl group at the end or an intermediate position thereof; R2 represents an alkyl group or an alkoxy group each of 1 to 10 carbon atoms or -C 3BOND N; and <IMAGE> represents <IMAGE> and when R2 represents -C 3BOND N, <IMAGE> represents <IMAGE>
