Abstract
Novel triphenodioxazines have been synthesized and evaluated. The dyes were not only highly dichroic in guest-host liquid crystal mixtures but also vi vid because of a sharp peak in absorption spectra. Mesogenic substituents t o the 2,9-position of the chromophore improve the order parameter in the mi xture. Moreover. the mixtures also showed significant polarized photolumine scence. These results would reveal a few advantages of the novel dyes for s ome possible applications.
