N-substituted anthraquinones in which the substituent group is at least partially cyclic, either cyclohexyl or aromatic, and including anils of 1,4- and 1,8-diaminoanthraquinone with p-alkyl- and p-alkoxybenzaldehyde, are pleochroic and form guest-host combinations with dielectrically positive anisotropic nematic liquid crystals. These combinations are of value in electro-optical display devices.
