Rod-shaped molecules based on 2-(2-hydroxyphenyl)benzothiazole (HBT) were synthesized and their liquid crystalline (LC) behavior as well as luminescent property were investigated. The synthesized molecules show a large Stokes shift, avoiding the self-absorption and resulting in the transparency in the visible range. These compounds are extremely miscible to a conventional room-temperature nematic LC up to 14 wt%, and the resultant mixtures exhibit a sufficiently large photoluminescent quantum yield up to 0.32. The key for the large quantum yield in LC is the introduction of conjugated groups into HBT that suppresses the nonradiative decay pathways in the dispersed state.
