More Information
Summary: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 A1 to A12: H, F, etc.; B1, B2: H, CH3; p, q, r, s , t: 0 or 1, provided that when q=0, at least one of A2 and A4 to A10 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-.
