Photoalignment Properties of Brilliant Yellow Dye

• Photoalignment properties of commercially available Brilliant Yellow (BY) diazo dye are investigated. By using ozone pre-cleaning procedure we succeeded in deposition of highly uniform BY films on different kinds of inorganic and organic substrates used in LCD manufacturing. Excellent photoalignment of nematic, smectic ferroelectric and reactive liquid crystals (LC) on BY films is observed. This alignment shows extraordinary high photo-and thermal stability. The distinguished alignment properties of this dye extend the field of the sulfuric azo dyes effective for photoalignment.
