Abstract
A study is presented of the optical order parameters and spectroscopic properties of 1,4-diaminoanthraquinone derivatives containing various substituents in the 2-position in a nematic liquid crystalline mixture composed of cyanophenylcyclohexane derivatives. The results are discussed in terms of the effects of the dye structure on the order parameters. By introducing a trans-4′-alkylcyclohexyloxycar-bonyl or aryloxycarbonyl group into the 2-position, blue dyes have been obtained which show high order parameters and solubilities.Keywords
