Three thermally-stable red dyes of azo, quinacridone and perylene derivatives were synthesized and dye-based color filters were manufactured for use in liquid crystal displays. The aggregation behavior of the dyes and their spectral properties in film state were investigated using field emission scanning electron microscopy and concentration-dependent spectroscopy. Aggregate size was related to the...
A series of structurally isomeric water-soluble azo naphthalene dyes were synthesized, and their thermal properties were examined by thermogravimetric analysis and differential scanning calorimetry. Dye-based color filters were also fabricated using the synthesized dyes. Transmittance (98.9%) at 650 nm and a wide color gamut (62.8%) were achieved using one of the color filters. All the prepared dyes...
