Phenylacetylene compounds are disclosed which are expected to exhibit high refractive index anisotropy, easy to mix with other liquid crystal compounds, has advantageous stability against light, and may be used as a material for producing various films and the like. The compounds are represented by the formula (1):wherein A<1 >to A<12>: H, F, etc.; B<1>, B<2>: H, CH3; p, q, r, s , t: 0 or 1, provided that when q=0, at least one of A<2 >and A<4 >to A<10 >stands for a C1 to C10 alkyl or alkoxy group optionally substituted with at least one F; m, n: an integer of 0 to 14, provided that when s=1, n is not 0, and when t=1, m is not 0; W: -CH2CH2-, -C=C-. |
