    摘要： Anthraquinone dyes are of the general formula:
    wherein R is a trans-4-alkylcyclohexyl, trans-4-cyclohexyl- cyclohexyl, trans-4-alkylcyclohexylcyclohexyl, p-(trans-4--alkylcyclohexyl)phenyl or alkyl, aralkyl or aryl group each of which may be substituted with specified organic groups; and R 2 is an alkyl, cycloalkyl, aralkyl or aryl group each of which may be substituted with specified organic groups; with provisos as to the values of R 1 and R 2 together.
    The dyes have a cyan color and excellent order parameter, solubility and stability.
    In an electro-optic cell, a liquid crystal composition (9) containing the dye is interposed between two facing electrode plates (8) and permits the realization of good color displays utilizing the guest-host effect of a liquid crystal.
