    摘要: Provided are novel acetylene compounds which are useful as a component for a liquid crystal composition used for a liquid crystal element, a liquid crystal composition containing said compounds and a liquid crystal element using said liquid crystal composition. The acetylene compound is represented by Formula (1):

            n-C m H 2m+1 -C≡C-A-Z 1 -B-Y 1 -R 1      (1)

    wherein m represents an integer of 2 to 24; R 1 represents a linear or branched alkyl group, a linear or branched alkoxyalkyl group, a linear or branched alkenyl group, or a linear or branched alkenyloxyalkyl group each of which may be substituted with a halogen atom; R 1 may have an asymmetric carbon atom, and the asymmetric carbon atom may be optically active; A and B represents a cyclic group such as a phenylene group, a biphenylene group, a naphthylene group and the like each of which may be substituted with a halogen atom.
