We report herein a triphenodioxazine dye, which is highly dichroic and luminescent in liquid crystal (LC). The dye shows remarkable polarization dependence resulting from its high orientational order up to 0.88: the dichroic ratios from its absorption and that from the emission reach 22.1 and 67.7, respectively. Such high order has never been reported for luminescent dyes in LC, thus showing appreciable potential advantage for some applications.
