Latest Patents
Yeuk Lung Ho holds a patent for "Bis-azo dyes for thin film polarizers and synthesis method." This patent describes a dichroic bis-azo biphenyl dye, where the substituents R, R, R, and R are alkyl or alkenyl groups with n ranging from 1 to 18. Notably, at least one substituent among R, R, R, and R is different from the others. The patent outlines a benzidine-free method for synthesizing this dye, utilizing a cross-coupling reaction, which may include a Suzuki reaction. The resulting polarizer, formed from a photoaligned layer of the bis-azo biphenyl dye on a substrate, exhibits a dichroic ratio of at least 40. Furthermore, chemical modification of the photoaligned dye layer results in a broad-band thin film polarizer characterized by low light scattering and high thermal and photo tolerances.
