| titleOfInvention | Anthraquinone compounds and liquid-crystal composition containing them |
| abstract | Anthraquinone compounds represented by general formula (I) and having a hue of yellow to yellowish orange, and compositions for liquid-crystal display elements obtained by dissolving said compounds in a liquid crystal, wherein X1 and X2 each represents a sulfur atom or a selenium atom, and R1 and R2 each represents a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted pyridil group, or a substituted or unsubstituted pyrimidyl or tetrahydronaphthyl group, provided that the following cases are exluded: (1) X1 = X2 = S and R1 = R2 = substituted or unsubstituted phenyl group; (2) X1 and X2 = S, R1 = substituted or unsubstituted naphtyl group and R2 = a phenyl or naphtyl group; and (3) X1 = X2 = Se and R1 = R2 = tetrahydronaphthyl group. |
