“…They can be easily prepared by diazotization and azo coupling reactions. This economic factor has led to the synthesis of many dyes in the past . Generally, azo disperse dyes containing aromatic heterocyclic moiety have been investigated because of their superior properties, and the use of heterocyclic diazo or coupling components in particular has made possible the production of colorants with brilliant color and chromophoric strength, high level‐dying property, and excellent fastness properties .…”

Ten novel fluorescent azo disperse dyes 2a–e (open forms) and 3a–e (closed forms) were obtained by the coupling reaction of carbocyclic amine based diazonium chloride with compounds 2 and 3. The synthesized dyes were characterized by elemental analysis, high‐resolution mass spectrometry, Fourier transform infrared, and NMR spectral techniques. Moreover, we investigated the substituent effect and solvatochromic properties of the dyes on absorption and fluorescence spectra. At the same time, the absorption and emission spectral data of the closed form dyes 3a–e were compared with the open form dyes 2a–e due to more planarity of the closed form dyes that lead to the extension of the π–electron conjugation.

“…Moreover, pigment-dispersed CFs have high brightness, transparency, and good colour reproducibility with a wide process margin [8]. Yellow azo dyes are widely used in colour filters as additives to blue, green, and red pigments to suppress 'parasitic' transmission in the blue range [11]. This problem can be overcome by reducing the particle size and improving the dispersion stability.…”

“…To resolve this problem, colour filters based on dyes or dye–pigment hybrid systems have been researched in order to improve colorant dispersibility . Yellow azo dyes are widely used in colour filters as additives to blue, green, and red pigments to suppress ‘parasitic’ transmission in the blue range . Pyridone derivatives used as coupling components are important colorants for yellow and orange dyes in industrial applications.…”

Nine yellow azo dyes were designed and synthesised by using different diazo components and pyridonyl coupling components for application in dye-pigment hybrid colour filters for liquid crystal displays. The synthesised dyes were characterised by proton nuclear magnetic resonance and elemental analysis. The thermal stability was examined by thermogravimetric analysis, and solubility was estimated in industrial solvents such as N-methyl-2-pyrrolidone and propylene glycol methyl ether acetate. The dyes, which exhibited suitable physical properties for use in a dye-pigment hybrid colour filter, were fabricated into colour filters, and their optical properties were measured.
