Abstract A study is presented of the optical order parameters and spectroscopic properties of 3′-hydroxyquinophthalone and 3,9-disubstituted perylene dyes in nematic liquid crystalline mixtures. The results of this study are discussed in terms of the effects of the dye structure on the order parameters. From the systematic variation in structure, it is found that a thioester group and a short flexible chain such as an n-butyl group play a significant role in increasing the order parameters. In addition, preliminary data on the solubility and photostahility of the dyes are reported.
